The EGR is on the intake in between the throttle body and the upper intake. The valve is on the back side of the EGR plate.
Gray87GT - By cutting off EGR you will have problems. Both drivablity and a possiblity of power loss. If I've said it once I've said it a million times, "if you are getting error codes, you're not running 100%" The computer does many things to keep you from screwing up the engine while codes are shown. If you drill out the hole for EGR, you're pretty much voiding out the heat resistant spacer you just put in. What they are made to do is keep the upper intake from getting hot so that the air entering the engine is colder. Most people don't get that you should disconnect your EGR water supply and return lines when you put in a heat spacer. The water lines are too cool the EGR spacer because it gets extremely hot from exhaust gas, however since you will no longer have EGR gas in the intake, you need to disconnect the water so that it doesn't heat up the upper intake. With a spacer that blocks EGR and no water to the EGR you should be able to run the car for a while and then touch the intake and it should be warm if anything. But not blazing hot like normal. Drilling the EGR hole and running a spacer would only slightly lengthen the intake ports and might add some torque or power, but it would be so minor that you would not tell. Anyway, if you are set on putting a spacer on, I have heard of people disconnecting water and running a spacer, no EGR hole and running fine, if you can handle the Check Engine light and annoying codes everytime you try and pull codes. Anyway, it's up to you. Just my $.02
