Disconnect the electrical connector ontop of the EGR, unbolt the EGR from the engine, and block off the 2 inlet ports (one on the lower intake manifold, and one on the read exhaust manifold).

It will keep your intake manifold cleaner (no recycled exhaust gases), and your temperatures a little lower. You may notice a slight drop in fuel mileage though (some people do, some don't). I like it mainly because it cleans up my engine bay, and my EGR was leaking, and annoyed the hell out of me.
