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.
- Easy-to-install kit adds a second stage of nitrous to any manufacturer’s single stage EFI nitrous system
- Faster than single stage systems because nitrous is added in two separately controlled stages
- Operated by a push button switch for ease of control
- Jets are included for adding an extra 50-250 HP
ZEX Nitrous' Direct Port Nitrous Systems feature a unique dual stage jetting system that gives much finer cylinder-to-cylinder tuning options. One jet is used in the distribution block and one jet is used in the injector nozzle, delivering perfect nitrous and fuel distribution. These kits use patented fuel adjusting nitrous nozzles for a 50-200 HP adjustable increase. Safe enough for stock engines and ideal for fully built competition engines. Active Fuel Control monitors bottle pressure and when nitrous is engaged, it adds or subtracts enrichment fuel so the engine never runs too rich or too lean.
