Unique One-Piece Housing with Sight Window:A custom computer designed housing eliminates the use of multiple components. It's roto-molded and made from heat soak resistant cross-linked polyethylene, ensuring the coolest air intake charge possible. A clear sight window allows for filter inspection without removal of the airbox. The housing is designed to retain the same stock mounting points as the OE intake system for a hassle-free installation. Large 5-Layer Performance Air Filter:This Momentum XP intake system was designed around the largest filter possible to allow maximum performance and filtration. Its unique filter-to-housing interface (US PAT 9440175) not only makes for a simple installation, but also allows for a large inverted 3.8x 9 air filter. The filter's Pro 5R media features five progressively finer porosity cotton gauze layers that provide maximum airflow and performance. Mandrel-Bent Tubing:A one piece 3.5 mandrel-bent brushed aluminum intake tube directs unrestricted airflow from the filter to the throttle body for more horsepower and torque. Premium Hardware:Premium stainless-steel t-bolt clamps provide the best corrosion resistance possible. Momentum XP intakes are designed with fewer parts for a quick and simple installation. Product Features:Dyno-proven power gains of up to +15 HP and +21 lbs. x ft.
