IAG Revolve Washer Fluid Reservoir Cap w/ Anodized Color Accent for 02-21 WRX, 04-21 STI, 05-09 LGT, 04-08 FXT

Ditch the unsightly yellow factory cap and transform your engine bay with the IAG Revolve Washer Fluid Reservoir Cap. Designed to fit 2002-2021 WRX, 2004-2021 STI, 2005-2009 LGT and 2004-2008 FXT Subaru Models, this attractive aluminum cap offers a perfect fit to the OEM washer fluid reservoir while enhancing the appearance of your engine bay with a clean, custom look.

The IAG Revolve Washer Fluid Cap outperforms Subaru’s factory plastic cap, which is prone to wear and failure due to extreme temperatures under the hood. This cap is precision CNC-machined at our facility in Maryland from 6061 billet aluminum, offering superior strength and durability. It features a sleek black anodized finish that is resistant to corrosion while giving your engine bay a high-end look.

The IAG Revolve Washer Fluid Cap stands out with a vibrant anodized aluminum insert in the center, available in your choice of silver, red, blue, black, gold, or purple. The insert is laser-etched to reveal a universal washer fluid symbol, but can be flipped to show the solid color. The inserts are easy to swap in seconds, thanks to the accessible design inside the cap—just use a small tool to pop the insert out and choose your preferred side.

For a more cohesive look under the hood, upgrade to an IAG Revolve Engine Bay Dress-Up Cap Kit. This complete set includes the Oil Fill, Brake Fluid, Coolant Reservoir, Washer Fluid, and Power Steering Reservoir Caps in your preferred color. If you want a custom touch, each cap is also available individually, allowing you to mix and match for a unique style.
