LBZ EGR Delete Kit: Benefits, Installation, and What to Know Before Buying

LBZ EGR Delete Kit – Benefits, Installation & Legal Guide

What is an EGR Delete & Why Do LBZ Owners Do It?

The Exhaust Gas Recirculation (EGR) system in the 2006-2007 6.6L Duramax LBZ engines recirculates exhaust gases back into the intake to reduce emissions. However, this can lead to:

  • Carbon buildup in the intake manifold

  • Reduced airflow and engine efficiency

  • Increased heat soak, hurting performance

An LBZ EGR delete kit removes this system, improving airflow and engine reliability while preventing future maintenance issues.

Top Benefits of an LBZ EGR Delete Kit

Installing an EGR delete kit on your Chevy Duramax offers several advantages:

✔ Improved Fuel Economy – Better airflow means more efficient combustion.
✔ Reduced Engine Heat – Less heat soak extends turbo and engine life.
✔ Cleaner Intake System – Prevents carbon buildup in the intake manifold.
✔ Enhanced Throttle Response – Smoother power delivery and better boost performance.
✔ Long-Term Reliability – Fewer EGR-related failures (cooler leaks, clogged valves).

For maximum airflow, pair your Duramax EGR delete with a high-flow intake elbow for unrestricted performance.

Installation Guide: DIY or Professional?

DIY Installation (Moderate Difficulty)

Most LBZ EGR delete kits come with detailed instructions. Key steps include:

  1. Disconnect the battery for safety.

  2. Remove the EGR valve & cooler (may require some wrenching).

  3. Install the delete kit & block-off plates to seal the system.

  4. Upgrade to a high-flow intake elbow (optional but recommended).

  5. Reconnect everything & clear any engine codes (tuner may be needed).

🔧 Pro Tip: If you're not comfortable with engine work, professional installation ensures proper fitment and avoids leaks.*

Legal & Emissions Compliance: What You Should Know

⚠️ Important: EGR deletes are not emissions-compliant in all states. The EPA prohibits tampering with emissions systems, and some areas require inspections.

  • Off-Road Use Only: Many kits are labeled for "competition use."

  • Check Local Laws: Some states (like California) enforce strict emissions testing.

  • Tuning Required: Removing the EGR may trigger a check engine light without a proper tune.

Always research regulations before modifying your 6.6L Duramax.
