New M52/S52 Performance Oil Separator Kit
Due to weak plastic construction, the factory plastic crankcase ventilation breather hose is known to fail. After years of exposure to piping-hot engine bay temperatures and chemical-laden oil vapors, the corrugated plastic tubing can crack, crumble, or fail altogether
Upgrade your M52/S52 CCV system with this durable silicone breather hose, designed to provide a comprehensive upgrade and permanent replacement for the factory plastic hose. By replacing the flimsy, heat-hardened OEM plastic hose with a four-ply fluorosilicone hose from Turner Motorsport, you'll experience peace of mind knowing your M5X- is free from the inevitable return of oil leaks, vacuum leaks, and drivability concerns that would have been.
This breather hose is found at the front of the engine, and is used to connect the cyclone separator to the valve cover. It replaces OEM part number 11151703775.
