Cold Air Intake
Manufactured by Skunk2, this cold air intake is now available in our shop for just $346.99. This is the best-performing, best-fitting intake system available for the ’12-15 Civic Si. This system 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. Uniquely designed, 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). Compared to competitors’ designs, Skunk2’s design positions the air filter downward-facing for approximately two inches of additional ground clearance to reduce the possibility of submerging the air filter during wet conditions.

Just recently purchased a 2015 Honda civic SI and i love it . I live in the Richmond VA area and was wondering if you could recommend a good place to get the additions for better performance added ?
Hello,
We sell parts all over the country. So we usually do not have recommendations as those places then tend to “steal” our sales 🙂
