BMW M Car G8X Series Blackline Performance Washer Fluid Cap

Introducing GoldenWrench’s full replacement Billet Washer Fluid Cap for BMW G8X M Series vehicles. Built with their no-spill seal technology, it’s designed to help prevent washer fluid leakage from the factory reservoir. This is one of GoldenWrench’s most complex components to date, meticulously engineered and produced in-house to the same high standard as the rest of their lineup, replacing the factory unit with an all-new form factor. It’s the newest addition to the BLACKLINE Performance product line for BMW G8X Series vehicles.

Upgrade the plain plastic factory cap with the BLACKLINE Performance Washer Fluid Cap. Each cap is CNC-machined from T6 aluminum and anodized in GoldenWrench’s signature finishes. Logos and detailing are completed using a precision 3D milling process, machined directly into each cap for a premium, OEM+ look. The BLACKLINE Performance Billet Washer Fluid Cap fits most BMW G8X Series models. Each kit includes the Billet Washer Fluid Cap and an installation instruction card. This is a full replacement that installs in minutes and eliminates the factory cap entirely.
