This air intake system produces up to 20 horsepower, 25 lbs. x ft. torque and out-flows the factory intake by up to 80%. Included in this system is a washable/reusable "oil free" conical air filter that uses three layers of progressive weave synthetic media for maximum convenience. The filter is constructed with 100% polyurethane for a long life and multiple cleaning cycles. This intake system also features a rotomolded tube that replaces the stock intake tract and directs increased air flow with improved volumetric efficiency for maximum performance. This intake system incorporates a unique coupling that smoothens the air transition into the intake tract, and also allows this kit to fit on both US and EURO Mass Air Flow Sensors. A one-piece black powder-coated heat shield requires little to no assembly for a hassle free installation.

5 IN Tall Conical Pro DRY S Air Filter: This intake utilizes a huge, 5 IN tall conical Pro DRY S performance air filter for increased performance. This 3-layer progressive, synthetic material air filter requires no oils and cleans with soap and water for maximum convenience.

One-Piece Filter Housing: The air filter is housed in a one-piece, black powder coated 16-gauge heat shield that keeps warm engine air out for maximum performance. This one-piece heat shield uses factory mounting locations and comes with all hardware for a hassle-free installation.

Compatible w/ Aftermarket HIDs: This system was designed to clear larger style HID headlight housings.

Fitment with EURO MAFs on US Specs cars:
On US specs cars converted to use the EURO MAF, this intake requires Tube Upgrade 54-12399 (sold separately) to fit correctly.
