On my 'new' Yellow Indy, I just pulled the EGR off of the intake, Dremeled-out the gasket just a little, and put in a penny. The car had over $7 in change under the seats, under the center-console, etc, and I dug through it until I found a 1990 penny -I'm just weird that way
. The copper of the penny crushes just a little between the EGR and the intake, sealing really well, like the copper crush-gaskets on brake-hoses. I remember we talked a bit about this on bstuff
, I was joking that I was going to develop a 'kit' for this, and charge $9.99.
I didn't bother blocking-off the exhaust-side of the mount because killing the gas-flow from the intake side is just as effective and ensures no air leakage into the intake, but dropping a coin in between the nipple on the exhaust manifold and the supply tube should work too, IIRC either a nickle or a dime fits right in. I haven't had any problems with the ECM expecting exhaust-gas flow causing the the engine to run weird at highway speeds (where the EGR would typically operate) or other low throttle-settings, and in fact the car seems to be getting better than 30MPG on the highway, despite having the three-speed TH125 auto (for now), so no performance complaints at all.

Warm-air intakes also help keep throttle-bodies from icing up, whereas a true CAI might
be more prone to that problem, but as I said, it takes a very specific condition within certain ranges of atmospheric conditions to actually cause a problem on port-fuel-injected engines (the TBIs on two of my Camaros have never
iced over either).
