I just went to a junkyard today and pulled an intake off of an explorer. I'm confused.
The explorer had the typical egr system you see on most late model fords, but the upper and lower intake manifold still have that little egr port that goes through the middle. Is it possible for the car to have the egr ports but it simply doesn't use it?
Now as far as performance gains with the cast upper intake will I see benefits over the stock upper on my mustang? Someone told me only the lower intake will give me gains and the throttle body.
