This hose directs the oil & combustion vapors from the valve cover and directs them to the intake manifold where they are put through combustion again in order to reduce emissions. When installing one of our N54 Oil Catch Cans the connections on this hose will often break. We recommend replacing this hose at the same time as your catch can. When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

Your engine's air fuel ratio needs to be dead on. Worn out factory pre-cat oxygen sensors delay vital data to the DME, leading to sub optimal fueling, lost horsepower, and dangerous hesitation under load.

This is the secondary air pump valve for E9x M3 with the S65 V8 engine. Over time carbon builds up inside the secondary air pump valve causing it not to close properly. This failure to close properly can allow exhaust and moisture to get past the valve and enter the secondary air pump, leading to premature pump failure.
