2004.5 - 2010 GM/CHEVROLET 6.6L DURAMAX PCV REROUTE WITH PORT AND RESONATOR PLUG
Take control of your crankcase ventilation system with this billet aluminum PCV reroute kit for 2004.5–2010 GM/Chevrolet 6.6L Duramax engines. Designed to reduce oil vapor contamination inside the intake system, this kit replaces the factory PCV connection points with high-quality billet plugs and reroute fittings.
Factory PCV systems on Duramax engines vent crankcase gases directly into the intake tract, where oil mist can build up in the intercooler, intake runners, and valves—leading to reduced efficiency over time. This kit allows users to reroute the PCV system externally (hose not included), helping to minimize intake soot buildup and maintain a cleaner, more efficient engine.
