Description

Large Five Layer Performance Air Filters:
Dual 360-degree radial flow air filters feature our pre-oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance. They provide your engine with the largest amount of high-flowing air, usually resulting in the highest power gains out of all our filter media options. This media is perfect for street and/or track use. Their inverted tops make for more filter surface area, resulting in longer service intervals.

Unique Housing With Cover:
The smooth housing, constructed of cross-linked polyethylene (XLPE), is used to minimize the number of components and ensure the coolest air intake charge available. The housing utilizes the factory OE air inlets. A vacuum-formed removable cover seals the system, ensuring cool air delivery to the engine, but can also be removed for extra air flow if desired.

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:
The computer designed system utilizes factory mounting locations, minimizing the use of unnecessary hardware and ensuring a perfect fit every time. Its innovative design makes for a hassle-free, direct bolt-on installation process that requires no cutting or drilling.
