Goldenwrench Supply BLACKLINE Performance Washer Fluid Cap - 2023+ Toyota GR Corolla

At Driven.Media, we’re proud to offer the latest from Goldenwrench Supply’s BLACKLINE Performance Series—the Billet Washer Fluid Cap for the Toyota GR Corolla (E210) and 2019+ Corolla Hatchback. This isn't just a cosmetic upgrade—it's a complete replacement designed to elevate your engine bay with precision, durability, and a race-inspired aesthetic.

Crafted in-house by Goldenwrench, this cap is CNC-machined from T6 aluminum, anodized in a striking race red finish to match the GR Corolla’s iconic engine cover accents. Built with no-spill seal technology, it combines form and function—keeping your washer system clean while enhancing the visual appeal of your bay.

Every detail has been obsessively refined. The 3D-machined BLACKLINE logos are milled directly into the billet, offering a premium tactile finish far superior to plastic factory caps. This is one of Goldenwrench’s most complex designs to date—engineered not just as an accessory, but as a statement.

Each kit includes:

• 1x BLACKLINE Billet Washer Fluid Cap (full factory replacement)
• 1x Installation Instruction Card

Compatible with:

• 2023+ Toyota GR Corolla (E210)
• 2019+ Toyota Corolla Hatchback (E210)

Upgrade your engine bay with one of the cleanest billet dress-up options available—trusted by Driven.Media, crafted by Goldenwrench.
