I have a piece of metal dryer vent tube lying around; I figure I'll probably stick it in there somewhere to just dump cold air up into the engine compartment and keep the whole under-hood environment a bit cooler. This wouldn't dump air directly at the filter because it would be on the other side of the heat shield -- it would just cool down the pipe and other stuff.

96 GL Zetec ATX, white with pinstripe, nickname " Sam Smooth "
mods so far: CTA intake with homemade heat shield, KVR drilled front rotors & carbon pads w/ 500° fluid
planned mods: exhaust (want to keep it quiet), e-ram (awaiting installation), diablo chip
involuntary mods: compression increased after head gasket failure
