Just out of curiosity, what is the non-Nismo 370Z radiator cap rated at? The Nismo one is rated at 137kPa or 0.137Mpa. The Nismo cap (aftermarket) is rated at 0.13Mpa....or roughly 130kPa. So wouldnt the aftermarket Nismo one be at a lower rating than the OEM Nismo 370Z version?

I would assume that changing out the radiator cap to a lower Mpa rating would then lower the boiling point correct?

Just wondering. Figured that I would leave the OEM cap alone and not change it for a "nicer"..."prettier" shiny Nismo badged one.
