NOS has pushed performance to a new level with their Pro Race Fogger nitrous oxide systems. They incorporate the latest technology for producing the largest horsepower gains of any single-stage system available today; and they feature stainless fogger nozzles for the ultimate in combustion, distribution and accuracy. These systems include NOS' famous R-series bottom-discharge solenoids, which have the least restriction and most flow of any design, and are adjustable to produce from 150 to 600 plus additional HP! They are designed specifically for use on highly modified competition-only engines, and come standard with the bottle and brackets, Super Hi-Flo valve (with nitrous gauge!), Y-shaped equal-flow distribution blocks for superior performance and accuracy, high-flow Y-fittings at all unions, and all other necessary mounting hardware for a complete installation. Racing fuel, racing ignition system with timing control, and internal engine modifications are required. Also available without bottle.
