Introducing GoldenWrench’s BMW S63 and S68 Engine BLACKLINE Performance Cap Set. Meticulously designed and produced in house to the same high precision and quality found across GoldenWrench’s lineup, this set gives the factory caps a cleaner, upgraded form factor and expands the BLACKLINE product family for the next generation of M vehicles.

Upgrade the plain plastic factory oil and coolant caps with the BLACKLINE Performance Engine Cap Set. Each cap cover is CNC formed from T6 aluminum and anodized in your choice of three colors: Anthracite Grey, Blue, or Red to complement the factory engine bay. Logos and detailing are completed using GoldenWrench’s precision 3D milling process, machined directly into each piece for a crisp, premium finish.

Fitment is for vehicles equipped with an S63 or S68 engine. Each set includes a Billet Oil Cap Cover and Coolant Tank Cap Cover or covers, depending on application. These are not full cap replacements. The billet covers mount to the top of the factory caps and install in minutes.
