Get rid of the unattractive OEM yellow cap and upgrade your engine bay with the IAG Revolve Coolant Reservoir Cap. Designed to fit 2002-2024 WRX, 2004-2021 STI, 2005-2009 LGT, 2004-2008 FXT and 2013-2024 BRZ Subaru models, this stylish aluminum cap provides an exact fit for the factory reservoir while enhancing the appearance of your engine bay with a refined custom appearance.
BETTER THAN OEM
IAG’s Revolve Coolant Reservoir Cap is a major upgrade over Subaru’s factory plastic cap, which is prone to wear and failure due to the extreme temperatures under the hood. CNC-machined at our facility in Maryland from 6061 billet aluminum, this cap is lightweight, durable and strong. It features a sleek black anodized finish that is resistant to corrosion while giving your engine bay a high-end appearance.
CUSTOMIZE YOUR CAP
The IAG Revolve Coolant Reservoir features an anodized aluminum insert, available in your choice of silver, red, blue, black, gold, or purple. The insert is laser-etched to reveal a universal coolant 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.
COMPLETE THE LOOK
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.
