Unique One-Piece High Quality Housing w/ Auxiliary Scoop:
The smooth one-piece high quality 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 large, clear sight window is used for a hassle-free filter inspection and an aggressive style. A urethane plug is also included if you wish to completely seal the airbox.

The air filter is wrapped in reinforced metal providing maximum strength to prevent filter collapse.
