Question about this product?

We're happy to help.

The Goldenwrench Blackline Performance BMW M Car S58 Engine Cap Cover Set is a precision-machined engine bay upgrade engineered for BMW M vehicles equipped with the S58 engine. CNC-formed from high-strength T6 aluminum and finished with an anodized coat and 3D-milled detailing, this cap set delivers a refined, motorsport-inspired look across both the oil cap and coolant cap positions — replacing flat factory plastic with purposeful billet components.

Available in Edition Red, Motorsport Blue, and Anthracite Grey, each cap receives its branding through advanced 3D milling rather than decals or paint — meaning the finish holds up to engine bay heat, cleaning, and long-term use. These are precision overlay covers that install directly over the factory oil and coolant caps, preserving OEM functionality and sealing integrity while transforming the underhood appearance. The design language is consistent with the broader Blackline product line, making this set a natural complement to other Blackline components already on the vehicle.

Installation requires no modification and no special tools. Covers affix over the factory caps and seat securely in place. The process takes only minutes, and the result is a clean, cohesive engine bay finish suited to both daily-driven M cars and show-level builds.
