Unique One-Piece Housing W/ Sight Window: 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 roto-molded housing is made out of cross-linked polyethylene red. It accommodates the "Hellcat" headlight air inlet for 2015 Dodge Challenger models only (Requires scoop P/N: 54-72203-S). Roto-mold Tube: This system uses a CAD designed, dyno-tuned, roto-molded red intake tube to achieve maximum power gains while maintaining a perfect fit. A billet aluminum fitting is mounted on the tube to provide a perfect connection for the temperature sensor. Large 3-Layer Performance Air Filter: This Momentum GT intake system was designed around the largest filter possible to allow maximum performance and filtration. This cone filter has a massive oval flange and is 9" tall inverted top Pro DRY S filter media. The Pro DRY S performance air filter features 3-layers of progressive finer porosity synthetic media providing maximum convenience with 100% polyurethane frame for long life and multiple cleaning cycles. Premium Hardware: Premium stainless steel T-bolt clamps and a reinforced silicone hump coupler are used for strength and durability while also providing the most secure installation available. Momentum intakes are designed with fewer parts for a quick and simple installation. 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 Department of Motor Vehicles.
