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 designed intake tube to fit with the stock mechanical fan and achieve maximum power gains while maintaining a perfect fit. Huge Pro 10R Performance Air Filter: The Momentum HD intake is designed around a massive 1,000cfm performance 360 degree radial flow air filter with 10-layers of progressive cotton media providing 99.59% cumulative efficiency (independently tested). 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. 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. 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.
