Goldenwrench Blackline Performance BMW M Car (S63 / S68) Engine Cap Cover Set – Edition Red

The Goldenwrench Blackline Performance S63/S68 Edition Red Engine Cap Set brings a precision-machined billet upgrade to the engine bays of BMW’s most powerful M vehicles. Designed specifically for models equipped with the S63 or S68 engine, this cap set replaces the factory plastic oil and coolant caps with CNC-formed T6 aluminum billet covers finished in a race-inspired Edition Red anodized coating.

Each cap is machined from high-grade T6 aluminum and anodized in Edition Red to complement the factory engine cover’s visual presence. All Blackline Performance logos and decorative markings are finalized through a precision 3D milling process, machined directly into each cap for a permanent, premium finish that requires no maintenance. The cap covers attach directly to the top of the factory caps, preserving OEM functionality while adding a significant visual upgrade with minimal installation effort.

No tools are required for installation. Each billet cover clips or affixes over the factory cap in minutes, making this one of the most accessible engine bay upgrades available for S63 and S68 platform vehicles.
