Goldenwrench Blackline Performance A90 Supra Edition RED Billet Washer Fluid Cap

The Goldenwrench Blackline Performance A90 Supra Billet Washer Fluid Cap is a full replacement unit for the factory plastic washer fluid reservoir cap on the 2020+ Toyota GR Supra (A90). Among the most mechanically complex pieces in the Blackline Performance product line, this cap incorporates built-in no-spill seal technology engineered specifically to address washer fluid leakage from the factory reservoir cap during high-speed cornering and heavy braking events.

Each cap is CNC-machined from high-grade T6 aluminum and anodized in Edition Red to complement the accent stripes on the factory engine cover. All logos and design details are created using a precision 3D milling process, machined directly into the aluminum surface for a permanent, high-definition finish consistent with the wider Blackline Performance product family. This is a full replacement, not a cover it fully removes and replaces the factory cap.

Installation is straightforward, removing the factory cap entirely and threading in the Blackline billet replacement in minutes. Each kit includes the billet washer fluid cap and an installation instruction card.
