Huge 3-Layer Performance Air Filter: The Momentum GT intake is designed around an oil-free, large 9" oval 360 degree radial flow performance air filter with 3-layers of progressive finer porosity synthetic media providing maximum convenience. The unique air filter to housing interface (patent pending) allows for maximum filter size which increases the available air volume while simplifying the installation process. The air filter is wrapped in reinforced metal providing maximum strength to prevent filter collapse. 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 completely seal 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. Premium Hardware: High quality premium clamps and a silicone bellow coupling are used for durability while also providing the most secure installation available. Momentum GT intakes are designed with fewer parts for a quick and simple installation. Emissions Disclaimer: This product does not require a CARB EO# (Vehicle does not exist in U.S.)
