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.
