Killer b Dual Reservoir Wash/Coolant - 2002-2005 WRX/STi

The end of an ERA. Our GD Dual Washer Reservior is going the way of the Dodo bird. The victim of evolution.

But WAIT! Our DWR2 Dual Washer Reservoir has been upgraded to fit GD models. Please check that product out here.

There may still be some of your beloved DWR1s out there for sale in the wild, so check in with our vast netork of authorized dealers.

The Dual Washer Reservoir from Killer B motorsport is designed to create more space in the engine compartment. Combining two reservoirs into a single component frees up space for intercooler tube placement, easier maintenance, access to the engine, and durability.
