Killer B Dual Reservoir Washer/Coolant 2002-2021 WRX/STI

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.

Installation instructions.

Fits all 2002-2021 Subaru WRX and WRX STI sedan models. Does not fit dual-pump wagon/hatch models.
