Momentum ST Cold Air Intake System w/ Pro DRY S Media DiscontinuedUnique One-Piece Housing: A custom CAD designed roto-molded housing made from heat soak resistant material eliminates the use of multiple components and ensures the coolest air intake charge available. The roto-molded housing is made out of black cross-linked polyethylene. It accommodates the "Hellcat" headlight air inlet for 2015-2016 Dodge Challenger models only (requires scoop p/n 54-72203-S). Roto-mold Tube: This system uses a CAD designed, dyno-tuned, roto-molded 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 5-Layer Performance Air Filter: This Momentum ST 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. The Pro 5R performance 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. Premium Hardware: Premium stainless steel worm-gear 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.
