There are several brands out there when it comes to aftermarket air intake systems, but Injen leads the way in innovation, efficiency, and power gains. Injen Cold Air Intake Systems are more than just a high flow air filter on a less restrictive tube.

At the end of the Injen Intake is the Injen High Flow Air Filter Element, which is relocated to an area behind your bumper and inner wheel well fender. This strategic placement allows you to obtain colder air while still having the air filter protected from the elements. The Injen air filter that can be cleaned and reused for as long as you own the vehicle. An incorporated velocity stack smooths out airflow to help maximize power gains.

Everything you need to install this air intake is included and the intake comes with a lifetime warranty.
