Features:

• Large Five Layer Performance Air Filter:

  This 9" 360-degree radial flow air filter features a 5" flange and our pre-oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance. It provides your engine with the largest amount of high-flowing air and delivers the highest power gains in most cases. This media is perfect for street and/or track use. Its inverted top makes for more filter surface area, resulting in longer service intervals.

• Unique One-Piece Housing:

  The included massive air filter is surrounded by an open-element XLPE (Cross-linked Polyethylene) polymer housing that minimizes warm engine air for maximum performance. Its open design allows for easy viewing of the air filter and delivers an aggressive Air Intake sound. The system utilizes the vehicle's OE air inlet with no additional hardware.

• 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 and hardware are included. Its revolutionary design, featuring our patent pending filter-to-housing interface, uses half the number of parts of a traditional cold air intake system.
