OEM 2011-2018 Infiniti M37 / Q70 PCV Breather Hose.
This hose is located on the valve cover. Gases that enter the crankcase are removed by the positive crankcase ventilation system or PCV. The PCV uses engine vacuum to draw fresh air through the crankcase. Over time this hose may wear down and crack causing the vehicle to lose power and become un-driveable. This hose is also prone to front end collisions and must be replaced.
Sold individually.
