This Stage-2 intake system produces up to 18HP and 20lbs. x ft. of torque over stock, while outflowing the factory intake by 49%. Included in this system is a washable/reusable "oiled" conical air filter that uses five layers of progressive weave media for maximum air flow. This intake system uses a 16 gauge steel heat shield that is positioned under the factory hood scoop to supply the air filter with cool, dense air for maximum performance.
- 360 Degree Air Filter: A huge inverted cone 360 degree round air filter is used for maximum air flow and filtration (98.6% efficient). The PRO 5R performance air filter features 5-layers of progressively finer mesh cotton gauze media and is constructed with 100% polyurethane for long life and multiple cleaning cycles.
- Top Mounted Heat Shield Design: aFe developed this heat shield to attach onto the top of the lower half of the factory air box to provide a hassle-free installation utilizing factory mounting locations.
- Bump Lock Filter Mounting Design: The air filter uses a unique bump lock flange design that allows the air filter to securely mount to the heat shield with no hardware.
- Simple Installation: The intake tube was engineered to fit the MAF sensor perfectly, without the use of a coupler. This eliminates hardware which allows for a simple, quick installation.
