???? not familiar with these. More info please.

It is the silver thing you see tucked in the hacked up air dam of your average import tuner car. Kinda looks like a radiator, but smaller.

Basiclly, you push intake-bound air through the cooler and the air moving through the grill cools it. Cooler air, denser charge, more power. It is like your radiator (which is an air/water exchanger) without the water in it.
