OE Performance Replacement
Barbed Connection Points For Hose
What's in the Box
(1) PCV Valve
(3) Plastic Elbow Fittings
The PCV (positive crankcase ventilation) valve is part of the positive crankcase ventilation system, which reroutes crankcase blow-by to the intake manifold and back to the engine, where it's re-burned in the cylinders as part of the fuel/air mixture. This cuts emission pollution and increases fuel economy because unburned fuel in the blow-by is consumed the second time around. It also keeps the blow-by and water vapor from fouling the oil in the crankcase, thus reducing the formation of engine sludge.
