Goldenwrench BMW M Blackline Oil Cap Heritage Motorsport
The Goldenwrench BMW M Blackline Oil Cap – Heritage Motorsport Edition is engineered to elevate the engine bay of early 2000s BMW M vehicles with a refined OEM+ aesthetic and motorsport-inspired detailing. Designed in-house from the ground up, this full replacement oil cap reimagines the factory component with improved materials, precision machining, and a more purposeful visual presence.
Manufactured from CNC machined T6 billet aluminum, each oil cap is finished in Goldenwrench’s signature Frozen Silver anodized coating for a clean, high-contrast appearance. The surface features the BLACKLINE Performance logo in a black infill process, complemented by subtle ghosted “G” logos that are 3D post-milled into the cap for a premium layered effect. This combination of materials and finishing ensures improved durability, resistance to heat, and long-term reliability compared to the factory plastic cap.
Designed as a direct replacement, installation is straightforward and can be completed in minutes using the factory mounting location. This upgrade provides a simple yet highly effective way to enhance the visual quality of the engine bay while maintaining OEM fitment standards.
