I have for sale an intercooler water spray kit would suit wrx or forester. I bought it from a guy that had it in a GT forester and i was going to install in my GT but now have decreased the boost and no longer need it. Has all wiring needed including relay, 18 pound hoobs pressure switch with vacum line, resovoir and pump and lines to run to bonnet scoop. spray tip and anti back flow valve i think is from and STI. everything needed to install in car including wiring diagram for forester which is pretty much the same for a rex i think. $100.

cheers.
