ZEX has developed an innovative wet nitrous system designed specifically for any dual throttle body EFI engine. Two nozzles, dual feed lines, all required hoses, wires and fittings have been engineered and manufactured for a perfect fit on any dual throttle body engine. You won’t find a more powerful or easy-to-install nitrous system on the market.
Active Fuel Control is a revolutionary nitrous tuning and safety feature. In your engine, a vacuum is created as nitrous gas is sprayed across the open end of the nozzle’s fuel transfer tube. As bottle pressure rises or lowers due to bottle temperature changes, the speed of the nitrous discharge varies to the same degree. This causes the level of vacuum draw in the fuel transfer tube to vary as well. This variable vacuum draw causes the ZEX nozzle to actually "pull" more or less enrichment fuel into the engine. This means your engine never runs dangerously lean or overly rich. The nitrous tune-up stays dead-on for maximum engine safety and power at all times.
Our throttle position sensor switch is truly innovative. For years, nitrous systems have been activated by use of crude push buttons and throttle arm activated micro switches. These devices were very difficult to install and were constantly failing because of the extreme temperatures found in vehicle engine bays. ZEX integrated advanced microprocessor control circuits into our nitrous systems so that they "learn" the voltage curve of an engines throttle position sensor. This enables our nitrous systems to activate at wide-open throttle, precisely and reliably, every time.
