Billetworkz Wiper Fluid Reservoir Cap - 2013-2021 Scion FR-S / Toyota 86 / Subaru BRZ / 15-21 WRX / STI

Refresh your engine bay with a subtle but high-impact upgrade. The Billetworkz Wiper Fluid Reservoir Cap replaces the faded OEM plastic cap with a precision-machined billet piece that brings clean, cohesive styling to your FR-S, 86, BRZ, WRX, or STI. It is a direct-fit replacement designed to deliver OEM-level function with premium under-hood aesthetics.

Key Features

• Precision Engineering: CNC-machined from high-quality 6061-T6 billet aluminum for durability and a perfect fit.
• Premium Finish: Available in multiple vibrant colors with anodized or powder coated finishes (depending on selection) for long-lasting corrosion resistance.
• Direct OEM Replacement: Installs in place of the factory wiper fluid reservoir cap with no modifications required.
• Enhanced Aesthetics: Minimalist design that instantly cleans up the engine bay and pairs well with other Billetworkz caps.

Why We Like It

This is an easy win for under-hood presentation. The wiper cap is one of those small details that can date an engine bay fast. Swap it to billet and the entire area looks sharper and more intentional.
