The follow up to GoldenWrench’s highly anticipated summer release, the Billet Oil Cap Cover, is here: the all new BMW M Car Series Charge Cooler Coolant Tank Cap Cover. This is one of GoldenWrench’s most complex components to date, meticulously designed and produced in house to the same high precision and quality seen across their lineup, giving the factory unit an all new form factor. It is the newest addition to the BLACKLINE Performance product line for BMW M vehicles.

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

Fitment includes most BMW vehicles equipped with the S55 and S63 engines that use the charge cooler reservoir tank and matching cap shape shown in the product photos, including F87 M2 Competition, F80 M3, F82 M4, F10 and F90 M5, and more. Please verify your cap shape matches the product photos before ordering.

Each kit includes a Billet Charge Cooler Tank Cap Cover and an installation instruction card. This is not a full cap replacement. The billet cover mounts to the top of the factory cap and installs in minutes.
