The Skunk2 cold air intake for 2012–2013 Honda Civic Si is a molded polymer system designed to retain the OEM battery and reduce intake air temperatures compared with aluminum tubing. The kit includes both upper and lower intake tubes, a serviceable air filter, and relocation hardware so the intake fits without cutting factory fender liners. Skunk2’s design prioritizes lower intake temperatures and straightforward direct-fit installation.
