YESHMA Oil Catch Can Kit with Silicone Hose — BMW N20/N26

The catch can itself is machined from anodized black aluminum, giving it the durability to handle constant exposure to heat and vibration in the engine bay without corroding or degrading. Inside, a double-baffle oil separator design forces blow-by vapors through two separation stages, pulling out oil mist and moisture efficiently while maintaining free, unrestricted airflow through the system. This means no negative impact on crankcase pressure or engine breathing — just cleaner air heading back into the intake.

YESHMA includes a silicone hose specifically engineered for this application, with strong resistance to mineral oil, liquid fuel, and elevated temperatures. That matters in a tight, heat-saturated engine bay — cheaper rubber hoses crack and degrade, defeating the purpose of the whole setup. With everything included in the kit, you're not hunting down compatible fittings or hose lengths before you can get started.

For N20 and N26 owners, this catch can is one of the most cost-effective preventive maintenance upgrades available. Extending the interval between walnut blasting services alone can save you hundreds over the life of the engine, and keeping intake valves cleaner means more consistent combustion, better throttle response, and fewer misfires down the road.
