Should I run an EGR or use a block off plate?

I am setting up a 5.0 with twin turbos, should I run an EGR or use a block off plate?

Do you even have heads and intake that allow for an EGR to function? I always ran the factory spacer with the valve in it but it did not do anything.

Well, the heads are Ford Racing Y303's and the intake is a Cobra intake mildly ported and polished. The intake has the spot for the EGR so I was wondering if I should put one on or use a plate?? I read a little about what the EGR does I posed my question.

Having it on there and not functioning is not going to hurt anything, that was the point I was trying to make. So unless you just like spending money then toss it up on there. For some reason I was remembering the Cobra intakes not using an EGR spacer but I think I am mixing 93 with 94-95 intakes in my head.

OK, I get your drift. I don't have either one right now and I figure the plate would be cheaper than the EGR valve, so thats why I was asking. If I definetly don't need it the the plate is the way to go. Thanks for your input.

Who is tuning the car. The a good tuner can turn off the EGR system so you dont get any codes.

Note this is for offroar use only.

As far as performace goes I have seen very little change in performance one way or the other.

I never bothered to get them turned off via a tune, I just plugged the wires up as if it could function, never through a code or any issues I ever detected.

Anytime I have checked for boost leaks the EGR valve is one of them... Block it off.

if you have a chance and have your lowering intake off. i would block off all exhaust gas flow to the upper intake, most intake gasket sets come with the small inserts you can put in to block the EGR holes in the head.

even deleting the EGR only still lets the EGR gas into the upper intake to heat it up, keeping the EGR gassers completely out of the lower and upper intake keeps the intake cooler.

you can use the little inserts or have it welded up.
