NOS has spent a significant amount of time and R&D evaluating the current jetting of its popular nitrous kits. With this testing, NOS has optimized the jetting of all of its plate kits and Fogger® kits. All of the nitrous kits old and new reflect this new optimized jetting. As a result, NOS has updated its jet kits and also released a few new kits so you can jet your nitrous kit to the horsepower that best suits your need.
To provide dealers with a large selection of jets for various applications, and to give racers a wide range of tuning options, NOS has assembled a number of Master Jet Packs. Also available are replacement plate jet packs, and eight packs for Fogger Direct Port kits.
