ZEX LSXnitrous systems are complete, easy-to-install kits that make big power for LSX ~~LS1, LS2, LS3, LS6, LS7 engines. Why not take your LS engines to the next horsepower level and add one of these ZEX LS systems? These kits add 75 to 300 hp and use a patent-pending injector nozzle that delivers optimum nitrous and fuel atomization. The kits also use advanced, patented electronics to activate at wide-open throttle. ZEX LSX nitrous systems use patented technology that monitors bottle pressure and adds or subtracts enrichment fuel for optimum performance. They come with custom-length distribution flex lines, so no cutting or bending of hard lines is required. These kits come complete with everything needed for installation.

100, 150 and 175 HP Jets Are included.

Also included is a purge kit and a billet aluminum bottle mount.

Plug and Play Nitrous Performance: All major components are contained in the ZEX NMU, which means you wont have any unsightly solenoids or wiring.

Worlds Only Smart Nitrous System: Uses actual bottle pressure to regulate the nitrous to fuel ratio, always optimizing the mix. Never too rich, never too lean.

With the power switch on, our nitrous kit only activates when you hit full throttle: This means you can sit at the line with the system armed and your hands on the steering wheel. When you hit full throttle, the nitrous automatically kicks in, you dont have to fumble with switches and steering at the same time. When you let off the throttle, the nitrous shuts off. Our difference in approach results in more horsepower per nitrous used through all bottle pressures.
