Description

The Boomba Racing Aluminum Coolant Overflow Reservoir Cap is a direct replacement for your Subaru WRX or WRX STI. It enhances the engine bay with a striking blue finish, upgrading from the standard yellow plastic unit. This cap is designed specifically for 2002-2024 WRX and 2004-2021 WRX STI models.

Crafted 100% in-house in the USA from aluminum, this cap offers durability and reliability. Installation is straightforward, requiring only the removal of the factory cap. Its robust construction is more resistant to wear and heat than the OEM plastic cap.
