This product was designed to create more space in the engine compartment. Combining two reservoirs (windshield washer fluid and coolant overflow) into a single component frees up space for intercooler tube placement, easier maintenance, access to the engine, and durability. A sight glass tube allows you to monitor the coolant level.
TIG-welded aluminum construction. Black powder-coat finish.
Fits all 2002+ Subaru WRX and WRX STI, including 2015 WRX+ and STI.
