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 NEUSPEED P-Flo allows you to uncork the intake side of your engine, drawing in a nearly unlimited supply of fresh air.  Most applications gain an honest 5-8hp at the wheels in the midrange and higher RPMs (depending on the vehicle.)   Plus, every P-Flo kit includes a high-performance, oiled multi-layer cotton gauze air filter that is washable and reusable. You also get an aggressive, deep throaty engine roar when you step on the gas pedal.
