Hey guys, I know that the newer TT Supra MKIV intercoolers are really good. I've also heard about the MKIII units...so I wanted to make sure that THIS is the MKIII unit. Also, how efficient is this IC and would it be good for around 350-400hp (in the future)? I don't want to spend another dime on an intercooler if I can get away with it and these seem to come up once and a while on ebay.
