yeah it is the part under the number mate with the little red dot on the right hand side, undo a couple of jubilee clips, then fit and forget
have you bought a dump valve? or a diverter valve?
if its a diverter valve then itll just be a straight swap, and should take about 10mins tops. the original is held in with strange clips i believe, which you have to cut off, so get some jubilee clips to fit that.
if its an atrmospheric dump valve, then itll need to be spliced into the front intercooler hose usually, just before the throttle body. itll also stop it running right and be generally nasty.
ok i got a pro to do it for me !!
i'll put some pics up in the next few days, along with some DIY instructions
