Unique One-Piece High Quality Housing W/ Auxiliary Inlet:
The smooth one-piece (Patent Pending) high quality sealed housing with auxiliary air inlet is used to eliminate the use of multiple-piece housings and ensure the coolest air intake charge available. A large, clear sight window is used for a hassle-free filter inspection and an aggressive style.

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.

Large 3-Layer Performance Air Filter:
The Momentum GT intake is designed around an oil-free, large 8-3/4" 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.

Custom High Temp. Silicone Coupling:
A custom high temperature reinforced silicone elbow coupling is included for easy install to the factory breather line.

Premium Hardware:
Premium stainless steel clamps are used for strength and durability while also providing the most secure installation available. Momentum GT intakes are designed with fewer parts for a quick and simple installation.
