u can see clearly in the link below that in 2012 370z models they changed the cooling system abit to make similar to the gtr which uses 0 pressure cap next to the engine and uses pressurized cap on the reservoir cap , in older models it was the other way around since older models had a plastic cap on the reservoir so in my case i will just reuse the 0 pressure cap next to the engine and leave the upgraded cap on the reservoir since stock suck ,
keeps u thinking why they did that ? hmmmm
