IAG Revolve Power Steering Reservoir Cap (02-07 WRX, 04-07 STI, 04-08 FXT)

TRANSFORM YOUR ENGINE BAY
Say goodbye to the dull factory cap and elevate your engine bay with the IAG Revolve Power Steering Reservoir Cap. Specifically engineered for 2002-2007 WRX, 2004-2007 STI and 2004-2008 FXT Subaru models, this premium aluminum cap seamlessly replaces the OEM power steering fluid reservoir cap. Not only does it deliver a perfect fit, but it also adds a sleek, custom aesthetic to your engine compartment.

OEM VENTING, BUILT TO LAST
The IAG Revolve Power Steering Reservoir Cap keeps Subaru’s proven venting system intact while adding a high-quality anodized aluminum surround. Since power steering fluid expands and contracts with heat, proper venting is necessary to prevent pressure buildup. The OEM cap achieves this through an expressly designed port and dipstick notches, allowing air to escape without leaks. We’ve combined these key features with our upgraded anodized aluminum exterior for a cap that’s both functional and stylish.

BETTER THAN OEM
By combining Subaru’s proven venting system with IAG’s precision-machined aluminum surround, the IAG Revolve Power Steering Reservoir Cap creates a stronger, more durable solution than the OEM cap alone. Precision CNC-machined from billet aluminum at our Westminster, Maryland facility, this cap retains factory functionality while providing an extra layer of reinforcement to the original factory part. Its corrosion-resistant black anodized finish adds both protection and a custom aesthetic to your engine bay.

CUSTOMIZE YOUR CAP
The IAG Revolve Power Steering Reservoir Cap features a vibrant anodized aluminum insert at its center, available in your choice of silver, red, blue, black, gold, or purple. The insert is laser-etched with a universal power steering fluid symbol, but you can flip it to display a solid color for a clean, minimalist look. Swapping inserts is quick and effortless—simply use a small tool to pop out the insert and choose your preferred side in seconds.

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 where applicable 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.
