Add a premium finishing touch to your BMW M engine bay with the GoldenWrench BLACKLINE Performance Heritage Motorsport Billet Oil Cap in Silver. Designed specifically for iconic naturally aspirated BMW M engines including the S54, S65 and S85, this precision-engineered oil cap replaces the factory plastic component with a durable billet aluminium alternative inspired by BMW's rich motorsport heritage.

Developed entirely in-house by BLACKLINE Performance, this full replacement oil cap has been engineered from the ground up to deliver superior aesthetics, durability and craftsmanship. CNC-machined from high-grade T6 aluminium and finished in a striking Frozen Silver anodised coating, it provides a premium OEM+ appearance while offering significantly greater resistance to heat and ageing than the factory plastic cap.
