Heat tranfer reduces the benefit of a CAI, and plastic/poly offer better resistance than metal. What if a CAI was made of plastic and had a outer
layer of insulation on it as well as the exterior of the air box that faces the engine compartment or was lined with a insulated interior?
A supplier on here had some numbers that claimed even a few degrees cooler in the intake temp. made several more hp.
