COBB Coolant Overflow Tank w/ Washer Reservoir Relocation Kit 2004-2007 STI

Declutter your engine bay and make space for upgraded intercooler piping with the COBB Coolant Overflow Tank and Washer Reservoir Relocation Kit. Originally included in COBB’s Front Mount Intercooler Kits for 2004–2007 WRX/STI models, this setup is now available as a stand-alone upgrade.

The aluminum overflow tank is powder-coated in wrinkle black for a clean, durable finish and mounts lower in the bay for a more streamlined look. The washer reservoir filler includes a Delrin base, cap, and tubing extension—designed specifically for 2006–2007 WRX/STI models with a bumper-mounted reservoir.
