...you don't really ever race; are never going to the track; drive the car as a weekend toy and have no major engine mods? You can see what mods I have in my signature. CAI, exhaust and a Predator are it in terms of performance. Would I stand to gain anything by installing the cooler temp thermostat? I'm sorry if this subject has been beaten to death but this seems like a very common mod and I need to know if I'd just be wasting money with it.
