monsta coolers are crap, mate fitted 1 and like in previous replies, struggled to maintain when we raised the boost.
if you want a quality intercooler, 1 i have fitted to my 33, call GK technologies on 0401 554 476, speak to greg krusse. he sells the kits complete with piping for 400 plus 20 postage or pick up from melb.
cheers
ps. not genuine greddy. sprayed on during car re-spray
