Expert's advice:
“The Mishimoto BMW N20/N26 Baffled Oil Catch Can is designed and engineered to reduce carbon buildup, a common issue with the direct fuel injection N20 and N26 engines. This baffled oil catch can will defend your intercooler, intake system, and VANOS system from oil-blowby 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 not only is extremely easy to install but also mounts the can in a serviceable location! Two aluminum, 3/4in barb fittings connect the hoses to the can.”
