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.
