Greddy Oil Coolers for FD3S

[yank]

I\'ve been wanting to order a GREX Oil Cooler Kit for my FD3S from //www.takakaira.com but they have four different types listed with no discription as to what the differences are.  I\'m guessing it is the amonut of rows but would like to know for sure before i part with the cash.  I\'ve emailed the guys at TK but have had no response and i need to order ASAP!  

Does anyone know???  Would be much appreciated.
