Zex Add-A-Stage Nitrous System

The ZEX™ Add-A-Stage Nitrous System upgrades any manufacturer's single stage EFI nitrous kit to a two stage system. A two stage system is faster than a single stage system because it gradually adds the nitrous power in two separately controlled stages instead of one big, tire-spinning hit. The Add-A-Stage Nitrous System is operated by a push button switch for ease of control, and jets are included for adding an extra 50-250 horsepower.

The Add-A-Stage Nitrous System incorporates several nitrous technology breakthroughs, making it the perfect choice for serious nitrous users. One such patent-worthy advancement is ZEX™ Fuel Shear™ technology, which injects the enrichment fuel directly into the center of the nitrous plume, yielding total and even fuel atomization. Active Fuel Control™ is a patented ZEX™ technology breakthrough that automatically adjusts fuel enrichment in accordance with bottle pressure so your system is never too rich or too lean, despite bottle pressure fluctuation.
