Was going to get a Mishimoto but they were on backorder and I have to get my car fixed so I spent the extra cash and got the Koyo. The radiator is in and it fit perfectly. I had to trim the upper radiator hose and thats about it. My problem is the two cap setup and the additional hoses. I found one thread on this but it didnt really answer all of my questions. First question is what cap do I need to get from Subaru? Does it need to be for an 04+ WRX or Sti or one for an 02? Also do I have to get this different hoses or can I just use the stock ones? Any feedback is appreciated.
