IAG Revolve Clutch Fluid Reservoir Cap w/ Anodized Color Accent for 02-14 WRX, 04-14 STI, 05-09 LGT, 04-08 FXT

Ditch the unsightly yellow factory cap and transform your engine bay with the IAG Revolve Clutch Fluid Reservoir Cap. Compatible with 2002-2014 WRX, 2004-2014 STI, 2005-2009 LGT and 2004-2008 FXT Subaru models, this attractive aluminum cap offers an exact factory fit and a secure seal while giving your engine bay a refined, custom look.

OEM Subaru clutch fluid reservoir caps are designed with a breather vent to prevent airlocks, and the IAG Revolve Clutch Fluid Reservoir Cap retains that functionality while adding a more stylish and rugged anodized aluminum surround. No need to replace the factory cap—just install the lower portion of your OEM cap into the IAG housing for a secure fit. This upgrade enhances your engine bay’s appearance while ensuring the exact ventilation needed to prevent vacuum issues.

By combining Subaru’s proven venting system with IAG’s precision-machined aluminum surround, the IAG Revolve Clutch Fluid 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 anodized finish adds both protection and a custom aesthetic to your engine bay.

The IAG Revolve Clutch Fluid 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 clutch 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.
