What Does an EGR Delete Do on a 6.7 Cummins?
What Does an EGR Delete Do on a 6.7 Cummins?

The 6.7L Cummins is a proven heavy-duty diesel powerplant used widely in Ram trucks for towing, hauling, and commercial service. While the factory Exhaust Gas Recirculation (EGR) system reduces nitrogen oxides (NOx) emissions, it is also associated with carbon build-up, increased service costs, and occasional reliability complaints. An EGR delete—the removal or blocking off of the EGR valve and cooler—has become a commonly discussed modification among diesel owners. This article explains what an EGR delete does on a 6.7 Cummins, the specific benefits it can deliver, whether tuning is required, and how a properly executed delete can affect the engine’s service life. How an EGR System Works (Concise Technical Background) The EGR system recirculates a portion of exhaust gas into the intake to lower peak combustion temperatures and reduce NOx formation. While effective for emissions control, EGR also returns soot, oil vapor, and hot gases to the intake tract. Over time these by-products promote carbon accumulation in the intake manifold, EGR valve, and turbo inlet, which can reduce airflow, impair turbo efficiency, and increase maintenance frequency. What an EGR Delete Actually Does？ An EGR delete physically removes or blocks the EGR valve and cooler and replaces the plumbing with block-off plates or reroute hoses. The practical effects are: Fresh air only enters the intake (no recirculated exhaust), which simplifies intake chemistry and reduces soot recirculation. The intake tract and turbocharger see less carbon contamination over time. The engine no longer relies on the EGR system to lower combustion temperatures; ECU behavior must be adjusted accordingly (see tuning section). A delete does not “magically” add horsepower by itself — the measurable benefits depend on the truck’s baseline condition, the presence of other restrictions (DPF, mufflers), and whether a proper tune is applied. What are the Benefits of an EGR Delete on a 6.7 Cummins? When executed correctly and used in the intended application, the principal benefits are: 1. Reduced Carbon Buildup Eliminating EGR flow prevents soot and oil vapors from reentering the intake, which reduces carbon accumulation on the intake manifold, valves, and turbo inlet. This lowers the frequency of intake cleaning and related repairs. 2. Improved Reliability in Heavy Use Trucks used for sustained heavy towing, off-road work, or commercial duty often suffer more from EGR-related problems. Deleting the EGR removes one common failure point and can translate to greater uptime where the truck works hard every day. 3. Cleaner Intake & Turbo Components Less soot means cleaner compressors and intercoolers, better turbo efficiency over time, and potentially fewer turbo replacements down the road. 4. Performance Consistency In many real-world cases, owners report steadier throttle response and more consistent power delivery after an EGR delete—especially when combined with a quality tune that optimizes fueling and boost control. 5. Lower Maintenance and Downtime By eliminating a recurring service item—EGR cooler and valve cleaning/replacement—owners can reduce maintenance costs and downtime. Caveat: These benefits are most pronounced for trucks that see a lot of low-speed, short-trip operation, continuous heavy loads, or off-road duty. Street-only trucks that are driven at highway speeds regularly may see smaller practical gains. Do You Need a Tune After an EGR Delete on a 6.7 Cummins? Yes. A tune is essential for safe and effective deletion. Why a tune is required: The Engine Control Unit (ECU) monitors EGR components and compensates for their presence. After removing the EGR, the ECU will detect divergence from expected sensor values and will typically log fault codes, illuminate the check engine light, or enter limp mode. A proper tune recalibrates fueling, timing, and boost control to account for the altered intake and exhaust conditions. This prevents fault codes, prevents drivability issues, and allows the engine to run efficiently and safely without EGR. A tune can be used to optimize power delivery, fuel economy, and EGTs for the new configuration. Types of tuning approaches: Pre-loaded tunes from reputable providers — convenient but less specific. Custom dyno tunes — best for maximizing performance and safety because they are tailored to the specific truck, hardware, and intended use. Handheld or cloud-based tuning devices — practical for field updates and easier installer workflows. Important: An improper or poorly calibrated tune can cause higher peak combustion temperatures, excessive EGTs, or poor fueling. That is why professional calibration (or experienced, reputable tuners) is strongly recommended. The All-in-One Off-Road Performance Kit for 6.7 Cummins Owners While an EGR delete alone can deliver noticeable performance and reliability gains, pairing it with a CCV reroute, DPF delete pipe, and a diesel tuner transforms the 6.7 Cummins into a far more efficient and powerful off-road machine. Here’s how the components work together: EGR Delete Kit – Eliminates exhaust gas recirculation, preventing carbon buildup and improving airflow.CCV Reroute – Redirects crankcase vapors away from the intake, keeping oil mist and sludge out of the charge air system.DPF Delete Pipe – Removes the restrictive diesel particulate filter, improving exhaust flow, reducing backpressure, and lowering EGTs.Tuner (e.g., EZ LYNK Auto Agent 3) – Optimizes ECU programming for the new hardware setup by: Adjusting fuel maps for efficiency and power Offering custom power levels for towing, economy, or performance Disabling related fault codes to avoid check engine lights Refining turbo boost and shift points for smoother operation The Result: With this combination, your truck benefits from cleaner airflow, improved turbo response, more power across the RPM range, and reduced maintenance demands. For off-road applications, it’s the most complete solution for unlocking the full performance potential of the 6.7 Cummins. How Long Will a Deleted 6.7 Cummins Last? There is no single guaranteed number of operating years for a deleted 6.7 Cummins—service life depends on multiple factors. However, with correct parts, installation, and tuning, a deleted engine can be at least as durable as a stock engine and, in many duty-cycle scenarios, more reliable. Key factors that determine longevity: 1. Quality of Components and Installation Use precision block-off plates, high-quality hoses, and professionally fabricated plumbing. Sloppy installation (leaks, improper fitment) raises the risk of problems. 2. Quality of Tuning A conservative, well-executed tune that manages fueling and boost will protect internal components. Aggressive or incorrect tuning can shorten engine life. 3. Supporting Modifications and Maintenance Proper oil change intervals, coolant system maintenance, turbo care, and intake inspections remain critical. Deleting EGR does not remove the need for standard diesel maintenance. 4. Operating Conditions Vehicles used for heavy towing, commercial hauling, or competition will experience more wear; however, deleting EGR can decrease soot-related wear in these contexts. Conversely, improperly tuned or improperly maintained deleted vehicles can suffer premature component stress. 5. Driver Behavior Conservative operation and attention to warning signs (boost anomalies, rising EGTs, oil consumption) will increase longevity. Realistic expectation: With a professional installation and tune, many owners report extended intervals between intake servicing and stable operation for tens of thousands of miles beyond what they experienced with an EGR-equipped truck. Conversely, if the delete is done poorly or left untuned, the risk of engine problems and shortened lifespan increases. Risks and Non-Technical Considerations Warranty and Legal: Deleting emissions equipment typically voids manufacturer warranties and is illegal on public roads in many jurisdictions. Deletes should be limited to off-road, competition, or private-property use where lawful. Emissions Impact: Removing EGR increases NOx emissions. This must be acknowledged and kept within legal and ethical boundaries. Resale and Compliance: A deleted truck may be harder to resell and will not pass emissions inspections in regulated areas. Conclusion An EGR delete on a 6.7 Cummins can yield meaningful benefits—reduced intake contamination, better reliability in heavy-duty use, and more consistent performance—provided the modification is executed professionally and paired with a correct tune. Tuning is not optional; it is an integral part of a safe, legal-compliant (off-road) delete strategy. When performed correctly with quality hardware and conservative, well-measured tuning, a deleted 6.7 Cummins can be as durable—or in many duty cycles more durable—than its stock counterpart. Poor execution, by contrast, substantially raises risk. 6.7 Cummins Delete Kit (Tuner Options Available) 2007-2023 Dodge Ram 6.7L Cummins CCV/PCV Reroute Kit $59.99 $29.99 Shop Now 2013-2018 Ram 2500/3500 6.7 Cummins EGR Delete Kit $166.99 $116.99 Shop Now 2019-2022 Ram 2500/3500 6.7 Cummins DPF Delete Downpipe Back $1070.99 $749.99 Shop Now 2013-2018 Dodge Ram 6.7L Cummins EGR/DPF Delete Kit with Muffler $699.99 $576.99 Shop Now 2010-2012 Dodge Ram 6.7L Cummins EGR/DPF Delete Kit  $417.99 Shop Now 2007-2009 Dodge Ram 6.7L Cummins EGR/DPF Delete Kit  $404.99 Shop Now FAQS About 6.7 Cummins EGR Delete Kit: 1.

What is an EGR Delete Kit? Everything You Need to Know Before Upgrading Your Diesel
What is an EGR Delete Kit? Everything You Need to Know Before Upgrading Your Diesel

As diesel truck owners seek greater power, improved fuel efficiency, and longer engine life, one modification frequently comes into focus: the EGR delete kit. The Exhaust Gas Recirculation (EGR) system, while essential for reducing emissions, often introduces carbon buildup, heat-related damage, and performance limitations. This is where an EGR delete kit becomes a compelling option—especially for those operating in off-road or race environments. But what exactly is an EGR delete kit? Is it good for your engine? Is it legal? What kind of horsepower can it add? This comprehensive guide will address all of these questions and more, helping you determine whether an EGR delete kit is right for your vehicle and your goals. What Is an EGR Delete Kit? An EGR delete kit is a set of components designed to remove the factory Exhaust Gas Recirculation system from a diesel engine. The EGR system is responsible for recirculating a portion of exhaust gases back into the intake manifold to reduce nitrogen oxide (NOx) emissions. Over time, however, this process introduces soot and carbon into the engine, leading to clogged intake passages, reduced airflow, and decreased performance. An EGR delete kit typically includes: Block-off plates or pipe replacements Gaskets and hardware Bypass components Instructions for physical removal Optional ECM tuning software or recommendations The goal of the kit is to completely eliminate the EGR system’s function, allowing the engine to run cleaner and more efficiently without recirculated exhaust gases. Is EGR Delete Good for the Engine? From a mechanical standpoint, deleting the EGR can offer significant benefits—especially for off-road applications: 1. Improved Engine Cleanliness: Without exhaust gases being routed back into the intake, there is less soot and carbon buildup. This results in cleaner intake valves and improved airflow over time. 2. Better Engine Reliability: EGR components, including valves, sensors, and coolers, are prone to failure. Removing them can reduce common problems such as coolant leaks, stuck valves, and sensor malfunctions. 3. Lower Engine Temperatures: Eliminating the EGR reduces intake temperatures and prevents the recirculation of hot exhaust gases, which helps the engine run cooler under load. 4. Enhanced Combustion Efficiency: With more oxygen-rich air entering the combustion chamber (instead of inert exhaust gas), fuel burns more efficiently, leading to better throttle response and potentially improved MPG. In summary, for diesel owners who operate in non-road-legal environments, an EGR delete is generally beneficial for engine health and performance when paired with proper tuning. Is an EGR Delete Kit Legal? No, in most jurisdictions, deleting or tampering with emissions control systems—such as the EGR—is not legal for vehicles driven on public roads. In the United States, for example, the Environmental Protection Agency (EPA) and state agencies enforce strict regulations that prohibit the modification or removal of emissions equipment. Violating these rules can result in: Fines for vehicle owners and service providers Failed emissions inspections Difficulty registering or reselling the vehicle However, EGR delete kits are legal for off-road, race, or farm-use vehicles where emissions compliance is not required. It is crucial to understand your local laws before considering an EGR delete. How Much Horsepower Does an EGR Delete Add? On its own, an EGR delete does not typically add a large amount of horsepower. However, when combined with proper tuning and supporting modifications (such as a cold air intake or exhaust system), you can expect gains of 10 to 30 horsepower, depending on the vehicle and setup. The real performance benefits come from: Improved throttle response More consistent power under load Increased combustion efficiency Reduced turbo lag For drivers seeking maximum power gains, an EGR delete is often one step in a larger performance strategy that includes a DPF delete, ECU tune, and aftermarket exhaust upgrades. What Happens If You Delete the EGR? When you delete the EGR system from your diesel engine: The intake stays cleaner, free from excessive soot buildup Engine codes and check engine lights may appear unless properly tuned The turbo system can run more efficiently, with lower exhaust backpressure The cooling system experiences less stress, as EGR coolers are eliminated Improper deletes without tuning can lead to limp mode or drivability issues Most importantly, deleting the EGR requires custom ECU tuning to disable related sensors and fault codes. Failure to do this properly may cause DTC codes and performance problems. What Happens If You Delete EGR Without Deleting DPF? Many diesel owners wonder if they can delete just the EGR and leave the DPF (Diesel Particulate Filter) in place. While it is technically possible, this approach is strongly discouraged for several reasons: 1. Increased Soot Load: Without the EGR, exhaust gas temperatures rise and produce more soot. The DPF must then trap more particulate matter, causing it to clog faster. 2. Regeneration Issues: The DPF relies on specific engine parameters, including EGR data, to perform active regenerations. A missing or disabled EGR system can interrupt this process, leading to incomplete regens and potential DPF failure. 3. ECU Conflicts: Most tuning solutions expect both EGR and DPF deletes to be performed together. A mismatch can lead to check engine lights, reduced fuel economy, and poor driveability. Therefore, if you're considering an EGR delete, it is highly recommended to pair it with a DPF delete and appropriate tuning to maintain system harmony and avoid performance issues. Is the EGR Delete Kit Worth It? The answer depends on your use case. Let’s break it down: ✅ When It’s Worth It ❌ When It’s Not Worth It The truck is used off-road, on farms, or in race applications Your vehicle is registered for public road use You want to reduce long-term maintenance costs You live in a region with strict emissions testing You’ve experienced repeated EGR-related failures You want to retain warranty coverage You plan to upgrade other performance parts and tuning You’re not ready to commit to a full delete and tuning solution You're seeking cleaner intake operation and cooler engine temps In conclusion, an EGR delete kit is worth it for off-road diesel owners looking to improve reliability and performance, provided it’s installed properly with compatible tuning and legal awareness. Other Considerations Before Deleting EGR Tuning Compatibility: Always use trusted, vehicle-specific ECU tuning when performing a delete. Generic tuners may cause poor performance or even engine damage. Coolant Rerouting: EGR delete kits often require rerouting of coolant lines. Follow instructions carefully or seek professional installation. Brand Quality: Use high-quality components from reputable manufacturers to ensure durability, proper fitment, and heat resistance. Cost vs. Savings: While an EGR delete kit may cost $300–$600 (plus labor or tuning), it can save thousands in future EGR-related repairs. Conclusion An EGR delete kit is a powerful modification tool for diesel owners seeking enhanced performance, cleaner engine operation, and long-term reliability—but it’s not a decision to take lightly. Understanding the technical benefits, legal implications, and tuning requirements is essential before proceeding. If you're operating in an environment where emissions compliance is not required, and you're prepared to delete your DPF and tune your ECM accordingly, then investing in a high-quality EGR delete kit can offer significant rewards.

Is EGR Delete Good for the Engine?
Is EGR Delete Good for the Engine?

The Exhaust Gas Recirculation (EGR) system has long been a standard component in modern diesel engines, primarily used to reduce nitrogen oxide (NOx) emissions and help vehicles meet environmental regulations. However, as emissions standards have tightened, many diesel owners have begun to question the long-term impact of these systems on engine performance, reliability, and longevity. One of the most common questions from diesel truck owners is: “Is EGR delete good for the engine?” This article explores the technical, mechanical, and legal implications of removing the EGR system, providing a balanced overview to help you make an informed decision. Understanding the Role of the EGR System The EGR system works by recirculating a portion of the exhaust gases back into the engine’s intake. This process reduces combustion temperatures, which in turn lowers the amount of nitrogen oxides (NOx) released into the atmosphere. While effective in reducing emissions, the EGR system also introduces certain drawbacks: Increased carbon buildup in the intake manifold and valves Restricted airflow and reduced engine efficiency Elevated exhaust backpressure More frequent maintenance and part failures For these reasons, many diesel enthusiasts and off-road vehicle owners consider EGR delete kits as a performance upgrade. Benefits of EGR Delete for the Engine 1. Improved Engine Cleanliness One of the most notable benefits of deleting the EGR system is the significant reduction in carbon buildup. The re-circulated exhaust gases are rich in soot and unburned fuel particles, which eventually settle in the intake manifold, EGR valve, and other components. Over time, this buildup restricts airflow and reduces combustion efficiency. By eliminating the EGR system, you stop this contamination at the source, resulting in: Cleaner intake pathways Reduced maintenance needs Longer-lasting engine components 2. Enhanced Engine Reliability EGR valves and coolers are known weak points in many diesel engines. They are prone to failure due to exposure to high heat, soot, and coolant leaks. Common issues include: EGR cooler cracking Valve sticking Sensor failure Removing the EGR system entirely eliminates these risks, improving the reliability and durability of your engine—particularly under heavy loads or towing conditions. 3. Improved Fuel Efficiency and Performance EGR systems lower combustion temperatures by introducing inert exhaust gases into the combustion chamber. However, this process also displaces fresh oxygen needed for efficient fuel combustion. By deleting the EGR system, the engine operates with a higher volume of clean air, leading to: Improved throttle response Increased horsepower and torque More efficient fuel combustion Potential fuel economy gains of 5–10%, depending on driving conditions and engine tuning Risks and Considerations of EGR Delete While the mechanical benefits are clear, it’s equally important to understand the potential downsides of an EGR delete. 1. Legal and Environmental Concerns In many countries, including the United States, removing the EGR system violates emissions laws for on-road vehicles. According to the Environmental Protection Agency (EPA), tampering with or removing emissions control devices—such as the EGR, DPF, or SCR systems—is illegal and subject to hefty fines. Therefore, EGR deletes should only be performed on vehicles used for off-road, race, or competition purposes. If your vehicle is registered for road use, you risk: Failing emissions inspections Losing factory warranty Receiving EPA or local government fines 2. Check Engine Lights and ECM Issues Modern diesel engines rely on multiple sensors and electronic systems to monitor emissions. Deleting the EGR system without proper ECU tuning will often trigger diagnostic trouble codes (DTCs), limp mode, or check engine lights. To ensure safe operation, you must: Use a compatible tuner or delete tune Reprogram the ECM to disable EGR-related functions Confirm that remaining systems (like the DPF) won’t be negatively affected 3. Impact on Other Emissions Systems The EGR system works in conjunction with other emissions components like the Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) system. Removing just the EGR while retaining the DPF can lead to increased soot production, more frequent regenerations, and eventual DPF clogging. For best results, many diesel owners opt for a complete delete kit, including EGR, DPF, and tuning, to ensure the entire system functions harmoniously. Is EGR Delete Right for Your Engine? Whether or not an EGR delete is a good idea depends on your specific goals and how you use your vehicle. Here’s a quick breakdown: Use Case EGR Delete Recommended? Why Off-Road / Race Use ✅ Yes Improved power, efficiency, and reliability Towing Heavy Loads ✅ Yes (with proper tuning) Reduces heat stress and part failure Daily Commuting ❌ No Violates emissions laws and may cause inspection issues Emissions Compliance Needed ❌ No EGR is required for legal road use Conclusion So, is EGR delete good for the engine? From a mechanical standpoint—yes. It offers substantial benefits in terms of cleanliness, reliability, and performance, particularly for diesel engines operating under high stress or heavy loads. However, it must be done responsibly, with proper tuning and within legal boundaries. If you're using your truck for off-road, farm, or race purposes, an EGR delete may significantly enhance your engine's performance and longevity. But for road-legal applications, it's crucial to stay within emissions regulations to avoid costly fines and complications. Before moving forward, always consult with a qualified diesel performance specialist to ensure the modification fits your vehicle’s setup, usage, and compliance requirements.

What is an EGR delete, and how does it work?An EGR delete involves removing or bypassing the Exhaust Gas Recirculation (EGR) system in a diesel engine. The goal is to prevent hot, carbon-laden exhaust gases from being recirculated back into the intake, which can reduce soot buildup and improve performance. 2. Is deleting the EGR system legal?EGR deletes are typically not legal for on-road use in most countries, including the United States, unless the vehicle is designated for off-road or competition use. Federal and state emissions regulations strictly prohibit tampering with emissions control systems. 3. Will an EGR delete improve my engine’s performance?Yes, removing the EGR system can result in increased horsepower, better throttle response, and improved fuel efficiency. This is especially noticeable in tuned diesel trucks designed for towing or off-road use. 4. Can EGR delete kits damage the engine in the long term?When properly installed and paired with appropriate engine tuning, an EGR delete typically does not harm the engine. In fact, it may enhance engine longevity by reducing soot and carbon buildup in the intake manifold and valves. 5. Does an EGR delete affect fuel economy?Yes, most users report a modest increase in fuel economy after performing an EGR delete, typically ranging from 1–3 MPG depending on driving conditions and engine tuning. 6. Is tuning required after deleting the EGR system?Yes, tuning is essential. A tuner is required to reprogram the engine control unit (ECU) so that it does not trigger error codes or enter limp mode due to the removal of emissions components. 7. Will I get a check engine light after deleting the EGR?Without proper tuning, the ECU will detect the missing EGR system and trigger a check engine light. A delete tuner or custom ECU tune is required to suppress these diagnostic trouble codes. 8.
