I was thinking of getting a aftermarket radiator. Is it worth it on a N/A car. I live in San Diego incase you are wondering about the weather conditions I live in.
I would say spend the dollars on other items. I have a Fluidyne Radiator (not cheap) but I only added it after I was supercharged and had bad over heating issues during the hot Texas Summer while driving up long hills. You live in one of the nicest climates in the USA, are you having overheating issues?
