2004.5-2010 Duramax PCV Crank Case Breather Filter Kit (114025405)
Engine runaway can be caused by oil vapor that travels through the crankcase breathers and into the intake system. Uncontrolled fueling of the engine is extremely dangerous. Upgrading the crankcase breathers and adding a PPE Filter Kit helps solve this runaway problem and stops normal oil vapor from contaminating the turbo, intercooler, and intake system. Other benefits of properly venting the crankcase are reduced internal engine pressures which will decrease the chance of seal damage and oil misting. Meets NHRA racing safety requirements.
OPTIONAL: Check Valve available separately (114025010).
