Crankcase Breather Set, Aluminum, 5/8" hose barb, GM Duramax 6.6L, 2004.5-2010

Pacific Performance Engineering crankcase breathers replace your stock plastic fittings with solid race performance. These PPE breathers allow you to route the breather hose (not included) from the turbo intake to a catch-can along the side/bottom of your engine. They're precision-crafted from billet aluminum and will aid in eliminating engine oil contamination of your intake system--while helping increase flow capacity to reduce internal engine pressures. Toss the plastic and install Pacific Performance Engineering crankcase breathers for top-quality racing performance.
