Unique One-Piece Housing:
The smooth one-piece sealed housing with auxiliary air scoop is used to eliminate the use of multiple-piece housings and ensure the coolest air intake charge available. A urethane plug is also included for extreme conditions when you want to block the auxiliary air scoop. A large, stainless steel plate is used for an aggressive style.

Roto-mold Tube:
This System uses a CAD designed, dyno-tuned, roto-mold intake tube to achieve maximum power gains while maintaining a perfect fit.

Huge Pro DRY S Performance Air Filter:
This Momentum HD is designed around a massive Pro DRY S performance 360 degree radial flow air filter with 3-layers of progressive synthetic media providing 99.2% cumulative efficiency. 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:
Premium stainless steel T-bolt clamps and a reinforced silicone coupling at the turbo inlet is used for strength and durability while also providing the most secure installation available. Momentum HD intakes are designed with fewer parts for a quick and simple installation.

Proven Results:
After a rigorous design and testing phase, the results are in. The Momentum HD intake system outflowed the factory intake by 43% and resulted in 19 additional horsepower and 33 lbs. x ft. torque.
