Large Three Layer Performance Air Filter:
This 8” tall 360-degree radial flow air filter features our oil-free Pro DRY S media with three layers of synthetic media for maximum convenience. Its progressive layering provides great filtration efficiency and dust holding capacity, while not requiring the use of oils. This media is best suited for street and light off-road use. 

Sealed Housing:
The included air filter is surrounded by a XLPE (cross-linked polyethylene) polymer housing with a anodized aluminum top that minimizes warm engine air for maximum performance. An additional auxiliary air inlet brings in additional air.

Dyno-Tuned Intake Tube:
This system features a high quality, computer-designed, dyno-tuned intake tube to achieve maximum power gains while maintaining a perfect fit. Its XLPE material is heat soak resistant and extremely durable.

Hassle-Free Installation:
This is a direct fit intake system that utilizes factory mounting points and requires no cutting or modifications. All necessary clamps, couplings, and hardware are included.

This intake system is not CARB exempt at this time and is not legal for sale in California or use on vehicles registered with the California Department of Motor Vehicles.
