Product Details

Engine crankcase ventilation depends on a sealed, properly routed breather hose to move vapors through the system and help control hydrocarbon emissions. This replacement hose is intended for BMW 325i, BMW 325is, and 1995 BMW M3 applications with the breather hose connected at the large valve cover connector. If the original hose is brittle, split, or leaking, part number 11151730507 restores the breather path and helps return the system to normal operation.

This part cross-references URO (e.g., URO-000452) for the same application.

Common Problems This Part Can Address
