EGR Delete Kits: Eliminate Carbon Build-up at the Source
The Exhaust Gas Recirculation (EGR) system routes hot exhaust gases back into your diesel engine's intake to reduce NOx emissions. While well-intentioned, EGR introduces carbon soot, heat, and moisture into the intake tract — leading to coked intake manifolds, sticking EGR valves, and reduced engine efficiency.
⚠️ IMPORTANT: EGR delete kits are intended for off-road and competition use only. Removing emissions equipment may violate federal and state laws. Please check your local regulations.
Benefits of EGR Delete
- Cleaner intake tract: Eliminates soot-and-oil sludge buildup in the intake manifold
- Lower EGTs: Reduces exhaust gas temperatures by 100-200°F under load
- Reduced coolant temps: Less heat rejected into the cooling system from the EGR cooler
- Improved throttle response: No hot, oxygen-depleted exhaust diluting the intake charge
- Prevent EGR cooler failure: Avoid coolant loss and hydrolock risk (6.0L/6.4L Powerstroke)
EGR Delete by Engine Platform
- Ford 6.0L Powerstroke (2003-2007): The most common EGR delete application. Complete kits include billet coolant bypass, intake manifold block-off plate, and up-pipe plug.
- Ford 6.4L Powerstroke (2008-2010): Dual EGR coolers require specific block-off plates for both banks.
- Ford 6.7L Powerstroke (2011+): Cooler bypass kits for the Scorpion engine.
- GM Duramax (LB7-LLY-LBZ-LMM-LML): Block-off plates and cooler delete pipes.
- Ram Cummins (5.9L & 6.7L): EGR cooler delete kits with intake horn blocker plates.
FAQ
Q: Will an EGR delete trigger a check engine light?
A: Yes, deleting the EGR system will trigger EGR-related DTCs. Proper tuning/ECM calibration is required to suppress codes and maintain driveability. This is typically done via tuner or custom tune.
Q: What's included in a complete EGR delete kit?
A: Most complete kits include: intake block-off plate(s), EGR cooler bypass pipe/hose, up-pipe block-off (if applicable), gaskets, and hardware. Some 6.0L kits also include a new intake gasket set.
