Skunk2 drew upon its experience and longstanding technical partnership with championship-winning Compass360 Racing when developing the Skunk2 Composite Cold Air Intake for the ’12-15 Civic Si. The results are the best performing, best fitting intake system available.

Skunk2’s Cold Air Intake is manufactured from molded polymer plastic for superior intake air insulation when compared to aluminum as well as for a smooth, continuous taper. When compared to aluminum, the thicker polymer material results in a superior thermal barrier and lower intake air temperatures. Each kit includes a 3.5-inch internal diameter lower tube and a tapered, 3.5-inch to 3.0-inch internal diameter upper tube that connects to the factory throttle body with a high-quality, silicone connector (larger diameter connector for use with Skunk2 throttle bodies or similar sold separately).

In an effort to reduce the possibility of submerging the air filter during wet conditions, Skunk2’s design positions the air filter downward-facing for approximately two inches of additional ground clearance when compared to competitors’ designs that locate the air filter from the side. That, combined with a design that doesn’t require cutting or modifying the factory fender liners, greatly reduces the chances of water entering the intake during wet conditions. Unlike other intake systems, only Skunk2’s unique design and brackets allow for the OEM battery to be retained.
