The Injen RD Series cold air intake swaps the restrictive factory airbox for a mandrel-bent 6061-T6 aluminum tube finished in wrinkle black powder coat, reaching low in the engine bay for the coolest, densest air available. Airflow passes through a fully serviceable Injen SuperNano-Web dry synthetic filter, a 2.75 in element that is washed and reused without oiling, and the tuned intake design keeps factory air/fuel ratios intact with no additional tuning. It holds CARB Executive Order D-476-8, so it is emissions legal for street use in California, and carries the Injen Technology limited lifetime warranty.
