COBB Coolant Overflow Tank (800660)
Upgrade the look and reliability of your 2015-2021 Subaru WRX or STI engine bay with the COBB TIG-welded Aluminum Coolant Overflow Tank. The factory plastic tank is prone to cracking from extreme heat cycles and creates clearance headaches if you're installing an aftermarket front mount intercooler (FMIC). This upgraded tank matches the stock 1L capacity while featuring internal and external anodizing for long-lasting durability. Designed for easy service with a single-fastener removal setup, it also streamlines charge pipe routing, cleans up engine bay aesthetics, and includes a heat-resistant Delrin cap, silicone adapter hose, and a matching injection-molded washer fluid reservoir cap.
Emissions Note: This part is not an emissions-related part and therefore can be used on emission-controlled vehicles.
