Introducing GoldenWrench’s full replacement Billet Washer Fluid Cap for BMW F Series vehicles. Built with their no spill seal technology, it is designed to help prevent washer fluid leakage from the factory washer fluid reservoir. 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 other products. It replaces the factory cap with an all new form factor and is the newest addition to the BLACKLINE Performance product line for BMW F Series vehicles.

Upgrade the plain plastic factory cap with the BLACKLINE Performance Washer Fluid Cap. Each cap 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 cap for a crisp, premium finish. The BLACKLINE Performance Billet Washer Fluid Cap fits most BMW F Series models, please see the application guide below.

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.
