ZEX 50-300 HP Dual Stage Wet Nitrous System for EFI Mustangs.The ZEX Dual Stage EFI Nitrous System is more effective than a typical single stage system because it gradually adds the nitrous power in two separately controlled stages instead of one big "hit" to give you a faster quarter mile ET. It also includes jets for adding an extra 50-300 horsepower and is a complete kit right down to the wire ties.
The first nitrous stage is activated automatically when you go to wide-open-throttle via the TPS-mounted switch. The second stage activates when you press an additional activation push-button.
-Fuel Shear Technology injects enrichment fuel directly into nitrous plume for better atomization
-Active Fuel Control adjusts fuel enrichment in accordance with bottle pressure so you'll never run too rich or too lean
