The Injen SP Series Cold Air Intake system is engineered to eliminate intake restrictions and maximize airflow to your turbocharged 2.5L boxer engine. This flagship system features mandrel-bent 6061-T6 aluminum tubing, providing a smooth, uninterrupted path for high-velocity air.

This kit includes a custom-designed heat shield to isolate the intake from engine bay heat and an Injen SuperNano-Web dry air filter, which offers superior filtration and airflow capacity without the maintenance hassle of oiled filters. This intake system is CARB legal (EO #D-476-8) for use in emissions-controlled states and is manufactured in Pomona, California.
