Actually, his kit is virtually identical to the STi sprayer. :lol: The STi uses a small poly tank in the trunk (much like the one in Demi's kit) plus a winshield sprayer motor (just like the one in Demi's kit).You can use the water sprayer from STI.
The water line runs along the passenger door sills and into the motor, then attaches to the hood like windshield spray lines do, but instead of popping through the hood to point at the glass, they attach to the hood scoop to point at the intercooler.
The only thing Demi is missing from the STi setup is a low-water warning light & float switch in the tank, and a momentary switch that sprays for 5 seconds after one press.
