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. The Mishimoto BMW N54 catch can kit uses the proven engineering from the patent pending Mishimoto 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 engineers at Mishimoto designed a CNC-machined lid which 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 aluminum, 3/4” barb fittings connect the hoses to the can. And, like every Mishimoto oil catch can, this baffled catch can kit comes with the Mishimoto Lifetime Warranty!

Our catch cans are different from most air-oil-separator (AOS) systems on a few levels. First, our catch cans are not heated. This means that all of the blow-by is able to condense in the can, including low-octane oil vapors and contaminated fuel vapors. Most AOS systems also drain the blow-by back into the oil pan, while our catch cans trap the blow-by and keep it out of the engine permanently. If you’ve seen what we’ve seen in the bottom of our catch cans, you won’t want that draining back into your oil either.
