      Zex Blackout. Is the standard "Purple" Zex kit a little to flashy for your taste? Well then checkout the Zex Blackout Nitrous System available from AmericanMuscle. The Zex Blackout System delivers the same exact power as before just with a subtle new look. The kit features a black powder-coated bottle, plate, fittings and carbon fiber-style hoses for an unprecedented new look.

      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 Blackout Nitrous Kit 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.

        First nitrous kit and Im hooked! Power gains are great for the money. Install took about 6 hours including bottle heater and pillar pressure guage. Only thing I didn't like was I bought the expensive autometer guage for the bottle pressure and the nitrous kit didn't have a fitting for it. For the money spent a $10 guage adapter should be standard. Plus American muscle doesn't carry the adapter for the guage.

        Great setup

        Zex black out is the way to go for more horsepower. Starting off with the 100 shot and feel is amazing. Just make sure you swap out the fuel pump so the engine gets the fuel it's needee

        Install was pretty simple as long as you have some skill, the blackout kit looks great the only problem I had was the wet nozzle and fitting were never sent in my kit so Im not sure who to blame

      I have a 95 Gt goin with afr 165 heads custom cam for blower.d1 sc/ juice what kit would be good for my combo a wet kit like this one or a dry

      • A wet kit like the ZEX Blackout Nitrous System would be ideal. We do not typically recommend dry nitrous kits, as a wet kit adds its own fuel to accommodate for the nitrous, whereas a dry kit does not, making it very difficult to tune a car using a dry kit to run safely.

      Can this kit go beyond 125hp by ordering bigger jets, or is 125hp shot the max?

      I have a 2001 GT with a super charger on 5 pounds of boost can I use this nitrous kit with no problems?

      • We would honestly recommend checking with your tuner as it will depend on the current build for your vehicle.

      Will be adding this kit with your 262 comp cams along with my bolt ons. When I order a programmer can u write a custom time for the nitrous and also without spray? Also what fuel pump do u recommend running with this kit to ensure proper fuel pressure?

      • Our Bama department offers Custom tunes and can certainly do so for up to a 100 shot. When it comes to fuel components it is best to speak with the tuner involved with the build as the answer to that question is entirely dependent on the tunes written for your vehicle. I will lend Bama's customer service line below: 1-888-226-9764

      92 GT do I need bigger injectors or any other supporting mods besides a tune?

      • The ZEX Blackout Nitrous System is a wet system, meaning it injects its own fuel, so injectors are not required. You will need to go with spark plugs of a colder heat range when using the nitrous kit, as well as a tune.
