NOS has spent a significant amount of time and R and 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(R) 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.
