The Goldenwrench Blackline Performance BMW E and F-Chassis M Car Series Oil Cap Cover is a precision-machined upgrade designed to elevate the engine bay of BMW M vehicles with a true OEM+ finish. Engineered from high-grade billet T6 aluminum, this oil cap cover replaces the factory plastic appearance with a motorsport-inspired component that delivers both visual impact and long-term durability.
Each Blackline oil cap cover is CNC-formed and anodized to achieve a deep, consistent finish in Edition Red, Motorsport Blue, or Anthracite Grey. For customers looking to match specific factory or Individual paint finishes, IND Exclusive color-matched options are also available, allowing seamless integration with your vehicle’s exterior and engine bay accents. The signature Blackline Performance Drip G logo and “use synthetic oil only” marking are precisely machined into the surface, reinforcing both authenticity and attention to detail.
Unlike full replacement caps, this billet cover installs directly over the factory oil cap using pre-trimmed automotive-grade 3M adhesive, making installation quick, secure, and completely reversible. This approach ensures compatibility while maintaining factory functionality and sealing integrity.
