Cold Air Intake

Unlock your engine's hidden power potential by replacing your restrictive stock intake with Injen's advanced SP Series Cold Air Intake. By reaching down behind your front bumper, it draws in colder, denser, fresher air for stronger, more efficient combustion.

More than just a cold air conduit, the SP Series Cold Air Intake is a high-tech, fine-tuned oxygen delivery system. The aerospace-grade T-6061 aluminum tubing is CNC mandrel bent, and the TIG welded brackets are perfectly positioned for a balanced fit inside your exact year, make and model. Plus, everything from the composite flanges to the urethane air filter is meticulously tested and tuned on Injen's in-house Dynojet.

Your SP Series Cold Air Intake is completely 50-state street legal. And, its unique rubber "vibra-mounts," stainless steel clamps and silicone hoses ensure a secure, shift-free installation.

Best of all, Injen backs your SP Series Cold Air Intake with a Lifetime Warranty.
