If you look at the stock intake setup, it is indeed a cold air/ram air design. This type of aftermarket air filter system (as in the ebay ad) is actually going to cause you to loose hp, not gain it. A open element air filter in our hot engine compartment is going to ingest hot air and very little cold air.

A heat shield on the filter would help but you really need to channel cold air from the grill or bumper area directly into the end of a shielded air filter.
