Unique One-Piece High Quality Housing:
A custom CAD designed roto-molded one-piece housing made from heat soak resistant material eliminates the use of multiple components and ensures the coolest air intake charge available. The roto-molded housing is made out of black cross-linked polyethylene. A urethane plug is also included if you wish to completely seal the auxiliary air scoop.

Hiqh 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.  Mounting tabs are molded in for easy installation.

Large 5-Layer Performance Air Filter:
This sealed intake system utilizes a pre-oiled, large 6-1/2" tall oval 360 degree radial flow performance air filter with 5-layers of progressive finer mesh cotton media providing  maximum airflow and performance. The unique air filter-to-housing interface allows for maximum filter size which increases the available air volume while simplifying the installation process.

Premium Hardware:
Premium stainless steel hardware and clamp are used to securely mount the high flow air filter and the intake tube. This sealed intake system is designed with fewer parts for a quick and simple installation.
