For Jeep Grand Cherokee owners with the 3.0L EcoDiesel (2014-2018 models), installing an EGR and DPF delete kit can unlock significant performance gains while reducing maintenance headaches. This comprehensive guide covers everything you need to know about EcoDiesel delete kits, including professional installation tips and answers to common questions.
Why Install an EcoDiesel Delete Kit?
Removing the restrictive emissions equipment on your 3.0L EcoDiesel provides multiple benefits:
20-30HP increase from improved exhaust flow
2-3MPG fuel economy improvement from reduced backpressure
Eliminates DPF regeneration cycles that waste fuel
Prevents EGR cooler failures (common $1,500+ repair)
Reduces engine bay temperatures for better reliability
Removes DEF system maintenance and associated costs
⚠ Important Note: Emissions modifications may not be legal for street use in your area. This information is for off-road use only.
