does it matter? i have 2 explorer intakes, i egr and one non egr. does it matter what one is used?

 

If you use the one without EGR you will have to accomidate the computer. By that I mean you will have to either have it's function turned off in the computer by a tuner or use an EGR delete circuit to make the computer think it's still there but just not moving. I have the delete circuit.

But, I would recommend using the one with EGR.

 

I am running a gt-40 non-egr lower and a tubular gt-40 upper. I have done the mass air conversion, I use the egr block off plate and un-plugged the connector and the car runs great and I haven't had any check engine lights or anything on my dash. I might have a problem if emmisions testing comes back but right now it runs good.

Probably wouldn't hurt to run the one with egr because that way if anything happened down the road with inspections you would'nt have to change much...

 

can the non egr lower be drilled for it?

 

not sure, it may be worth it at that point to just swap intakes, you know...

 

You have nothing plugged into the harness where the EGR valve plugs in? That's unusual that it runs good. Most, myself included, had problems with nothing there.

As far as drilling the intake, I don't see how that would work. The EGR passage runs all the way from the head up to the hole in the center.

 

i was running a explorer lower, and cobra upper, i run no egr, no problems yet

 

nope...maybe my check engine lamp is burned out...but it runs really nice.

 

na Stewart, I run the non egr ones when ever i can. Less hot exhaust running through the manifold.
