BMW OEM F8X CS Water Drain

A subtle but purposeful detail, the F8X M3/M4 CS engine bay water drain adds a clean OEM touch that sets it apart from standard models. Originally designed to channel water away from the cowl area, this factory-installed component not only enhances engine bay cleanliness but also serves as a clever integration point for catch can setups—making it a smart choice for enthusiasts pursuing OEM+ modifications.
