Those with a T4 what intercooler kit are you running? I'm between the 2 Row V and R spec. According to Greddy the difference with the R spec is mainly for use with there turbo kit as well, along with fin design. Would the R spec have larger piping turbo side? I can't remember the outlet of my compressor. I want to say 2.5, but, I've heard the vspec is only 2.25. Someone please shed some light for me. THanks
