Expert's advice:
The Mishimoto BMW N54 Baffled Oil Catch Can is designed and engineered to reduce carbon buildup, a common issue with the direct fuel injection N54 engines. It uses the proven engineering from 2-Port Compact Baffled Oil Catch Can with a 50-micron bronze filter and an internal baffle to better separate the oil from the crankcase vapors.
The CNC-machined lid features large inlet/outlets to match the inner dimension of the CCV hose. This baffled oil catch can defends your intercooler, intake system, and VANOS system from oil blow-by and help maintain proper octane levels to reduce potential detonation.
The kit comes with two direct-fit hoses, which require no modification to the engine cover, and one direct-fit mounting bracket that is extremely easy to install and mounts the can in a serviceable location! Two aluminium, 3/4" barb fittings connect the hoses to the can.
