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 â€“ where most performance drivers need it. The P-Flo Air Intake Kit 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. VW Golf VI 2.0L TDI 140HP 2010-2015, Jetta V & VI 2.0L TDI 140HP 2009-2015 with engine code CBEA and CJAA only.
