is the nismo radiator car only for boosted cars or can it work for naturally aspriated cars also...case in point will it fit on my naturally aspriated 2003 G sedan..thanks for the help

 

will it fit? sure, boosted or not, most likely you are going to use the same radiator. even if your replace the radiator most import caps are just about the same size. Its almost like a one size fit all things, as i've only seen 2 sizes, a really big one about the size of a pop cap top and then the normal one now which is the sizeof a golden dollar coin.

a nismo one i believe only increases pressure, not 100% on ratings. But in many cases its not a performance modification at all. So if you were hoping to gain something from it look somewhere else. nismo t-stat and caps are mainly bling mods first and function last.
