Constructed with 100% polyurethane on all four sides, this high flow, oiled OE replacement performance filter will out flow stock paper filter for improved horsepower and torque. Five layers of progressively finer mesh cotton gauze media provide maximum airflow for best performance results.

Would you ever run a marathon breathing out of a small paper bag?  So why ask your engine to rev all the way to redline breathing through the restrictive factory airbox?  The plastic factory airbox is good at muffling intake noise and enhancing low rpm/low speed engine performance, but becomes very restrictive when the engine is operating in the higher rpm range – where most performance drivers need it.

The VF-Engineering big turbo kits took countless hours of R&D and testing. The induction pipework, especially the air intake design was critical to achieve optimal driveability under part throttle, full throttle, and deceleration.
