Gain Up to 175HP. ZEX Wet Injected Nitrous Systems include 75, 100, 125, 150, and 175 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 2011 to 2014 Mustang GT, equipped with the Four Valve 5.0L V8 Coyote engine.

Technical Notes. Professional Installation recommended.

      Does this require a tune?

      • According to the instructions (and everything else I've heard) yes you should get a tune. 75 hp shot is fine without one (according to the instructions... although I would still get it tuned) anything above 75hp DEFINITELY NEEDS A TUNE or you could have "detonation" occur which can do some SERIOUS damage... hope this helps.

      Can this also be used on the s550s?

      • Unfortunately, this ZEX Wet Injected Nitrous System will only work with the 11-14 Mustang GTs, and would not work with a 2015+.

      fitment/ safety? im assuming this will fit the 2013 as well? also how safe is this system on the 5.0, i no the rods and crank are good for the hit but im not so sure about the pistons... thanks for the help

      • Zex Systems are SUPER SAFE compared to other systems. They have the technology that precisely meters exactly the correct amounts of Nitrous and Fuel and are considered by most to be the safest systems out there. I wouldn't think twice about adding this system to my car. Personally I am a supercharger fan, but for the money, you can't be a Zex shot for performance!
