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 as one big "hit", to give you a faster quarter mile ET. 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. It also includes jets for adding an extra 50-300 horsepower and is a complete kit, right down to the wire ties.
