I have a cracked radiator and I am replacing it. I have just a few things done for perfomance to the engine, a chip, intake and exhaust. I plan on doing a few more things to it, but not too much. would it be a good idea for me to get an upgraded radiator, or should I just stick to stock. Another thing is, I may want to make it faster in the future.If so, what is a good radiator to throw in, for a reasonable price.
