If it is a v6, it is located next to the distributor. Facing the engine it is on the right side of fuel injectors just under injector cover. You can see it from the drivers side.

Another Location in 1998 Honda preludes for the EGR (at least in mine) is at the top left of the engine block, just behind it. Here's a crude Diagram.

........................Big Silver intake valve here

EGR here

Why you would want to know is beyond me. I personally disconnected mine and plugged the hose leading out from it, bypassing it completely and making my engine run better.
