what the heck does "FWI, PEM, AND EGR DELETE" MEAN?

**SD GTP** · 01-03-2008

Most delete the EGR system when installing headers. ZZPerformance sells small plates with block off the holes in the Intake Manifold and on the Rear Header.

I believe I have some pictures around from after my header install that I can post up soon

Made my own EGR block off plates from some scrap 1/4" thick aluminum.

Many make their own with a penny and the left over clamps/mounting ends of the OEM EGR unit.

You don't really notice that much of a gas mileage drop. Your intake stays cleaner, and cooler is the main gain. But if you have state inspections...this is a no-no-go mod to do.
