Heyy everyone this topic has prob been talked about befor i dont want to start any arguments or anything, everyone has there own believes. but just want to know some of the Gains use have gotten with replacing a factory r32 gtr cooler to a after market one. such as greedy, HKS, ARC ect.
Also if the engine is high comp (9,1) dos this play a role in how thick the cooler should be ect.
cheers Anz
