Smart Nitrous Oxide Kits
For your performance car, Zex™ has designed the ultimate "Smart" Nitrous System. Depending on the application, the additional 55-125 horsepower it provides will have you tearing up your competition. The ZEX™ Nitrous System, using our patented technology, uses bottle pressure to regulate the nitrous to fuel ratio. This ensures the greatest level of engine safety.

Once armed, the kit is activated at wide-open throttle by an electronic sensor that "learns" the voltage curve of your TPS sensor. This design ensures your nitrous is engaged at the perfect throttle point, every time. The design of the ZEX™ Nitrous System makes it the simplest, safest, and easiest to install kit on the market.
We now have new application kits for the Chevrolet LT1, Ford EFI 5.0, and VW EFI applications.

Be on the look out for the new Zex Wet Kit.  Available in a few weeks.

Plug & Play Nitrous Performance:
All major components are contained in the ZEX™ "NMU", which means you won't 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!

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 don't 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.

Will the ZEX™ N2O kit work on my car?

• Our nitrous kit is very universal by design. It works on most late model, direct port fuel injection kits.
• ZEX™ Nitrous Compatibility Checklist
  
  • Engine must have a vacuum ported fuel pressure regulator
  • Throttle position sensor voltage must pass the following test:
    • Locate the T.P.S. (usually directly across from throttle linkage)
    • Turn ignition to on position (do not start engine)
    • Using a digital voltmeter, check each wire for a low voltage reading of approximately 1 volt.
    • Only one wire should have this low voltage with the throttle closed
    • While on that same wire, open the throttle completely and check the voltage reading
    • If your voltage reads 4.2 volts or higher, you are ready to install your ZEX nitrous kit

How much time can I expect installation to take?

• A person familiar with common hand tools should be able to complete the installation in three to four hours. If you can get out of bed by 8, it should be in before lunchtime.

Where can I get the nitrous bottle filled?

• Quality speed shops will be able to fill the bottle. Alternatively, most welding gas suppliers can fill the bottles.

Will your kit work on my car if it does not have a vacuum operated fuel pressure regulator?

• No, our nitrous kit is not compatible in your application due to the absence of a vacuum ported fuel pressure regulator. The required fuel enrichment comes by way of this style of fuel pressure regulator.

My car has high mileage, is it safe to run nitrous on it?

• High mileage is not necessarily an indicator of a car's mechanical condition. The better mechanical condition your car is in, the safer it is to use any high performance product. If you are not sure on the condition of your vehicle, take it to a qualified mechanic in your area for a complete inspection.

How much horsepower does the ZEX™ kit add?

• The ZEX™ kit is adjustable in three horsepower increments. Jets are provided that will give anywhere from 55hp to 125hp, depending on which kit you purchase.

Do I need to upgrade my fuel kit to use your kit?

• Our kit was designed and tested for use with stock fuel kits. It will perform properly on stock and mildly modified engines, i.e. header, K&N filter, exhaust, etc. If major modifications have been performed, i.e. camshafts, heads, porting work, intake manifolds, etc. It is strongly recommended that a fuel pump and injector upgrade be performed on your engine before using your ZEX nitrous kit.

Do I need to use different spark plugs when using the ZEX nitrous kit?

• It is highly recommended that you install non-projected nose style spark plugs that are 2 heat ranges cooler than stock plugs. For best results, use our Hyperformance™ triple electrode spark plugs. These spark plugs were designed specifically for nitrous, turbo, and supercharged applications.

How long will one bottle of nitrous last?

• This totally depends on which jetting is used. The 55hp shot will last around 3 minutes of continuous use. The 125hp shot will last just under 1.5 minutes of continuous use. Generally, since each race lasts less than fifteen seconds, many races can be run from a single bottle.

What makes your ZEX™ kit better than other brands?

• Our kit is self regulating and adjusts fuel pressure according to bottle pressure.
  
• It is TPS activated, which means no throttle switch brackets to rig up.
  
• The control box houses the solenoid for a cleaner installation.
  
• We include a one year warranty on our Zex kits.
  
• The convenience of toll-free support.
• Finally, we are confident that our kit is the easiest on the market to install.
