I was reading a magazine and I saw the word "NOS " as listed for a modification. And I started to thinking. If you use the word as an acrynom it would be technically correct, Nitrous Oxide System, even though you dont have the Holley brand. But if you out right just said NOS as in, " I have NAWZ," it would be rice, right? I guess the question is, is it rice to just say NOS even if you dont have the Holley brand?
