Default A.I.R. and E.G.R. delete

was just curisous as to how to remove these, thinking about getting a new set of headers that doesn't have the A.I.R and E.G.R. fittings, do i just make a block off plate for the back of the intake or what?? I know the A.I.R. pipe get taken out completley, just don't know what needs plugging and such

The big one is for the EGR valve itself on the driver side back of the intake manifold. The long one is the hole next to it on the pass side and the littlest one looks to be the hole on the exhaust manifold itself.

The AIR is electric and bottom driver side. Easiest piece to remove. The rest I can't help on since yours is different from mine. If yours is anything like mine, after removing the AIR, my car idles smooth as silk.

BTW, if you go with non-emissions headers, then you won't need that little plate. I just made some myself, however. If you go ahead and delete the AIR pump before a header swap, you'll have to plug the big AIR ports on top (a bolt will work).

Just block the back of the Intake, remove the crap on the side of it for the EGR, and cap that little connection and you are good.

Do you all pull the intakes to block it, or just weasel your hands in there to install the block off plates?

Yes (even on 94+ I still think so) and I would assume so. The computer doesn't like things unplugged.
