how do you fit a dump valve to an 03 sti? and where the hell is the origional on it?? sum1 please help!!

 

Loads of info if you do a search. If not circular gold coloured object to the bottom right of the intercooler on a triangular base, replace like for like with Dv fitting kit.

 

Personally I wouldnt bother. I replaced my standard recirc with a SSQV and am about to swap it back, but thats up to you. 10mins to swap em over hardest part is the large pipe which connects to the bottom of the DV with a sprung clip. I tried swapping mine back to original last weekend and after half hour trying to get the pipe back on gave up in the rain and put the SSQV back as the pipe was easier to get on lol.
