Crafted with precision from high-quality 6061-T6 aluminum, this intake system offers a smooth airflow path that reduces restrictions and maximizes engine performance.

The included fully serviceable SuperNano-Web dry air filter provides increased surface area for greater airflow and superior filtration, ensuring your engine breathes clean and performs reliably over time. The heat shield is custom-designed to fit your vehicle precisely, protecting the intake from under-hood heat and maintaining consistent performance. The Wrinkle Black finish adds a sleek, aggressive aesthetic that complements your engine bay, with options for multiple finishes to match your style. This short ram air intake system is engineered to maintain safe air-fuel ratios across the power band, ensuring reliable and efficient operation. Built in Pomona, California, USA, the Injen SP intake is backed by a limited lifetime warranty, offering peace of mind alongside its performance benefits.
