Goldenwrench Blackline Performance Toyota GR Corolla Washer Fluid Cap - Edition Red
The Goldenwrench Blackline Performance Toyota GR Corolla Washer Fluid Cap is a full-replacement billet upgrade purpose-built for the E210 platform. Designed with integrated no-spill seal technology, this cap resolves the seepage tendency of the factory plastic reservoir unit while replacing it with a precision-machined component that complements the GR Corolla's performance character. The anodized Edition Red finish is matched to the red accent stripes found on the factory engine cover — a deliberate detail for owners who care about underhood cohesion.
Each cap is CNC-formed from T6 aluminum, with all branding and Blackline logos machined directly into the surface using 3D milling. There are no decals, no surface stickers — just permanent, precision detailing that holds up to heat cycling and engine bay washing. Produced entirely in-house, this is among the most technically complex pieces in the Blackline lineup, built to the same standard as every other component in the product family.
Installation is tool-free. The billet cap replaces the factory unit completely, threading into the existing reservoir mount and seating with the integrated no-spill seal. Each kit includes the billet washer fluid cap and an Installation Instruction Card. The entire swap takes only minutes.
