The smooth one-piece sealed housing is used to eliminate the use of multiple-piece housings and ensure the coolest air intake charge available. This System uses a CAD designed, dyno-tuned, roto-mold intake tube to achieve maximum power gains while maintaining a perfect fit. The Momentum ST intake is designed around an oil-free, large 9" Tall conical flat top 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. Premium stainless steel worm gear clamps and a silicone coupler are used for strength and durability while also providing the most secure installation available.
