Unique One-Piece High Quality Housing W/Sight Window: 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. A large clear sight window allows for filter inspection without removal of the air box. The roto-molded housing is made out of black cross-linked polyethylene. A urethane plug is also included if you wish to block off the auxiliary air inlet. High Quality Tube: This system uses a high quality plastic CAD designed, dyno-tuned, roto-molded intake tube to achieve maximum power gains while maintaining a perfect fit. 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 large (6-3/4" x 4-3/4") oval flange and is 9" tall with an inverted top. 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: High quality premium clamps ensures the most secure installation available. Momentum intakes are designed with fewer parts for a quick and simple installation.
