WI is to spray fine water mist into the charged air prior to the intake manifold to reduced temperature of charged air and to prevent detonation. More useful for turbo setup than SC setup. Requires tuning. Does not increase hp/torque but rather maintain hp/torque numbers under heat soak condition. I'd suggest you don't worry about this mod unless you're tracking the car.

Good memory!

Yes, we did tap it from the washer tank. The idea is to minimize plumbing and extra equipment. With the nozzle I am using, one tank is good for 3 track sessions of 25mins each. Then again, it depends how hard I drive.
