Goldenwrench Blackline Performance S58 Frozen Black Cap Complete Set - BMW M2/M3/M4 (G8x) 2021+

The Goldenwrench Blackline Performance S58 Frozen Black Complete Cap Set is a six-piece billet aluminum engine cap set built specifically for BMW M models equipped with the S58 engine. Finished in a Frozen Black anodized coating, this set brings a stealthy, refined look to the engine bay while delivering the material quality and precision machining that define the Blackline Performance product line.

Each cap cover is CNC-machined from durable T6 aluminum and finished in the Frozen Black anodized coating for long-lasting durability and a clean, subdued visual presence. Precision 3D-milled logos and detailing are machined directly into each piece for a permanent finish that will not fade or chip. This limited release now includes a billet hood latch release handle alongside the full engine cap cover set, completing the under-hood transformation in a single kit. Note that the included hood latch handle is compatible with LHD (Left-Hand Drive) vehicles only.

Installation is straightforward — each billet cover attaches securely over the top of the factory caps with no modification to the vehicle, keeping the upgrade fully reversible and bolt-on.
