Why You Should Delete Your EGR On Your Diesel

31457

Since the EPA began requiring diesel manufacturers to include an EGR (exhaust gas recirculationthey have proven to do more damage than good. The EGR was an attempt to decrease the amount of pollution the engine creates.

While the EGR decreases the pollution entering the atmosphere by a minimal amount, they decrease the engines ability to breathe and can decrease the fuel economy as well. EGRs, take the black soot, exhaust gasses, and channels them directly back into the cylinders.

This takes space in the combustion chamber where there could be air, as well as clog up and cover all of the parts with soot. The problem compounds itself to the point that the engines are starving for air and running poorly.

One of a diesel’s biggest performance factors is air volume. The engine needs as much air as possible so that it will perform to its full potential. It is in your best interest to delete this system as soon as possible which will require a tuner to modify the computer so it will function properly.

Although it is best to delete the system entirely with a full delete kit, in states that require annual vehicle inspections if you do not have the EGR, your vehicle will not pass. There are a few alternatives to a full delete such as a blocker plate to stop the EGR valve from opening, or on some models you can simply have a tuner disable it from the computer.

Deleting your EGR will ultimately help ensure the longevity of your diesel engine, improve fuel economy, and you may even notice some performance improvements. Have you deleted your EGR? Tell us in the comments below!
