NOS

Term used for nitrous oxide. Somewhat incorrect since NOS is a company that produces nitrous oxide, also the company is pronounced as spelled...N, O, S; opposed to the common pronounciation similar to the word "gnaw" except with an "s" sound at the end. This term was put into play mainly by the movie series of "The Fast and The Furious". Most people that say the "gnaws" pronounciation of this have no clue what they are talking about with cars and are what you would consider "wanna be's"

Im going to go say NOS (gnaws pronounciation) cause it was in a movie.

NOS

term used for a nitrous oxide setup in a rice rocket, which is ironic seeing as how laughing gas is being used in a joke of a car.

NOS

NOS is the term commonly used for Nitrous Oxide, though NOS really stands for a company that distributes Nitrous Oxide for use on cars. There are various companies that Distribute Nitrous Oxide for cars, including NOS and NX(Nitrous Xpress). Though the movie "The Fast and Furious" features the NOS brand and glorifies it's usage, NOS is not the best brand for usage. Nitrous Oxide, in fact, is and should be the last ressort for a modified car. It may be considered "cheap" for use in the streets.
