This is the same coolant overflow tank and washer reservoir filler combination that comes with our front-mount intercooler kits for the 2004–2007 WRX and STI. It helps to tidy up the engine compartment and tuck the overflow tank lower and out of sight when used alone. helps keep the engine bay neatly constructed of aluminum and powder coated in a wrinkle-black finish. A Delrin base, Delrincap, and tubing extension make up the Washer Reservoir. It is specific to WRX/STI models from 2006–2007, which have a reservoir hidden under the bumper cover. Use the COBB Overflow Tank and Washer Reservoir filler to clean up your engine bay and gain additional room for intercooler piping.
