Nitrous Oxide Systems (NOS) was founded in 1978 by well-known drag racers Mike Thermos and Dale Vaznaian to market products utilizing N20. Through introducing precisely metered amounts of nitrous and petrol into an engine, tremendous gains in power were obtained essentially as a result of increasing combustion pressure. This underscored the need to improve the potency of available pump petrol, and the net result is NOS Octane Booster. It is formulated to eliminate the preignition (pinging) common to lower octane petrol and helps in all situations from towing heavy loads on steep inclines in a stock vehicle to racing with nitrous oxide at the track.
