Crankcase Pressure Oil Cap

By replacing the factory oil cap, this unit allows for efficient pressure relief, which helps reduce crankcase pressure and improve turbo oil drainage. This breather is a serviceable component that requires periodic cleaning to maintain proper functionality. It can be used in conjunction with the stock PCV system or paired with aftermarket oil catch can setups for increased pressure relief. Please note that fitment can vary based on valve cover design and surrounding engine components. Compatibility is specific: do not use this on S63, S63TU, or S68 platforms, such as the F90 or G90 M5, as installation on these non-recommended applications is at the user's risk and voids return eligibility. If installing on any engine other than the N54, you must close the hood carefully and verify clearance before operation. If the part does not fit, it must be returned in unused condition.
