Pros and Cons of an EGR Delete Kits

Deleting the EGR on a diesel engine creates several pros and cons.

Pros

• Elimination of harmful contaminates being reintroduced back into the engine.
• Warm exhaust gases being sent away from the engine through the vehicles exhaust system.
• Increase in the Diesel mpg. Some people experience gains of almost 5 mpg making this a very fuel efficient modification.
• Engine coolant will not be as warm because it doesn’t have to cool the exhaust like it did when the EGR was still on the vehicle.
• Increase in the longevity of the engine because it will be running cleaner and more efficiently.
• Depending on the truck one has you can experience faster turbo spool up.
• Coolant will flow faster through the engine because it will not be diverted by the EGR cooler.
• Less likely to have a blown head gasket.

Cons

• Increase in EGT because the non oxygen containing exhaust is not being readmitted back into the cylinder to keep EGT’s low.
• Some of the cons would be created by the oil cooler on the 6.0 Powerstroke but they can be prevented by regular maintenance. Other Diesel engines may differ depending on design and year model.
  • Flush coolant
  • Change coolant filter
  • Some people install new oil coolers during EGR deletes to decrease chances of having a faulty cooler creating a leak and more down time because of engine repair.
