The one-piece sealed housing is used to eliminate the use of multiple components and ensure the coolest air intake charge available. A large, clear sight window allows for filter inspection without removal of the air box. The housing mounts directly into the factory location on the fender well to capture the coolest air available from the factory intake tract. This system uses a CAD designed, dyno-tuned, roto-molded intake tube to achieve maximum power gains while maintaining a perfect fit. This tube has a built-in resonance chamber to catch un-wanted air intake noises. This intake system was designed around the largest filter possible to allow maximum performance and filtration. The Pro 5R air filter features 5-layers of progressively finer mesh cotton gauze oiled media and is constructed with 100% polyurethane frame for long life and multiple cleaning cycles NOTE: 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 DMV.
