Description
Gain Up to 125HP. ZEX Wet Injected Nitrous Systems include 75, 100, and 125 shot jets that will get your Pony flying down the track faster than you ever thought possible for less money than you'd believe. It doesn't get cheaper to add that much power to your Mustang.

Advanced Electronic Control. ZEX's Wet Injected Nitrous system uses patented "Active Fuel Control" that automatically adjusts nitrous fuel enrichment with bottle pressure. The result is that your engine never runs too rich or too lean, preventing engine damage. Unlike other less expensive systems, the ZEX "Wet" nitrous systems activate at wide-open throttle using advanced electronics that monitor your engine's throttle position sensor voltage to ensure activation at precisely the right time. This makes using your nitrous system very easy and reliable.

Better Nitrous Delivery. Unlike "dry" nitrous systems which inject nitrous directly, ZEX Wet Nitrous Systems connect to your fuel system and controls the amounts of fuel and nitrous using their management unit. The result is better control, complete fuel atomization, and more power.

Application. This Zex Wet Injected Nitrous is designed for use on the 1986-2004 5.0 and 4.6 V8 Mustangs with the stock fuel rails. System requires a minimum fuel pressure of 40 PSI.

Technical Notes. Professional Installation recommended. Requires fuel pressure of 40 PSI.

  • you will need to have the bottle filled up, they come empty when you order them. to be on the safe side, buy a window switch (AM has one for cheap), this will allow you to set a certain RPM range for the nitrous to be allowed into the engine (no detonation). bottle heater is very helpful. you can also buy a purge kit, which will deplete all the 'air bubbles' trapped in the lines, giving you a more controlled nitrous boost. hope this helps.

    Easy, clean, fantastic installation

    This kit is extremely well done. A major highlight is the flexibility of installation. Everything you need to install the kit is included and then some. It has various fittings, adapters, and hardware to meet any type of fuel supply needs, it also includes all electrical connectors and enough wire to allow different arming switch mounting options. The different nozzles are easy to install making it simple to adjust the size of the shot. The kit includes a tap for threading the nozzle into a metal intake, OR a grommet for installing into plastic intake pipes. This kit is much more complete and much simpler to install than many comparable set ups. The control unit itself is compact, easy to hide or mount, and much cleaner in appearance and installation than other kits. Other kits using mechanical wide open throttle switches are no comparison for the accuracy and ease of the unit that relies on the throttle position sensor signal. The kit did not skimp on braided line, so there is plenty of flexibility with bottle mounting and line routing. My only complaint would be that american muscle did not stress the importance of tuning the vehicle as much as they should. No where in the product description does it mention the need for timing adjustments and proper fuel selection. These are requirements that would taken into consideration by a professional but maybe not by the general public, so please note, even on a modern electronically controlled engine, it is safer to run this kit with a professional tune that delays ignition timing to prevent detonation, it is also necessary to use premium 91 octane or better fuel when running nitrous. Once those requirments are met, this kit offers an easy, clean installation, and exceptional performance. **please note, i could not use the proper language for "timing delay" because it flags the "r" word as inappropriate language.....

    zex wet kit

    I have done a lot of research and found that a 2v 4.6l will only hold upto 100 shot. I is amazing when it comes into play. I wired My kit through tration control because zex said if tration control came on while spraying your motor is done. I wish that would add something to watch that also. otherwise its a great kit.

    Best Way For Power

    Have zero complaints with this kit and was easy to install. I made 310 hp and 410 tq at the wheels with a custom tune on only the 75 shot. Also ran a 13.8 sec 1/4 at altitude in Denver this past summer. Next is the 100 shot/ tune and cheater slicks to plant the power to the ground. Great product!
