We replaced a bent intercooler from a minor accident and I pieced back together cracked bumper parts and stuff with zip ties and epoxy. We installed a the oversized ebay intercooler and it fit just fine and according to the owning his iat is on avg 10degrees colder . I have a modded r53 and we did a run to just over 100mph and I'm sorry to say but my r53 beat it by around 5 mini lengths but all the r56 had was rear cat delete and exhaust and the larger intercooler.
