• Dual-stage jet technology gives separate tune-ups for both speed-density and mass-air equipped vehicles.
Other kits on the market ignore the differences in these two engine operating systems.
• Unique nozzle design has “Active Fuel Control” built in. This feature monitors bottle pressure and when the
nitrous system is engaged, it adds or subtracts enrichment fuel so the engine never runs too rich or too lean.
Quick Start Reference Guide
How the ZEX 4 Cyl. Direct Port Nitrous System works: The ZEX 82030 nitrous system begins with
a connection to a supply cylinder containing pressurized liquid nitrous oxide and a connection to the engine’s
fuel system. These connections go to the system's nitrous and fuel solenoids, respectively. These solenoids are
normally closed, but are opened when the nitrous system is armed, and the throttle switch is activated by going
to wide-open throttle. Once these solenoids open, the nitrous and fuel are delivered to the nozzles, via braided
stainless steel delivery lines. The amount of nitrous and fuel that is injected is adjustable by means of metering
jets installed in the distribution blocks and the nozzles. These metering jets allow for easy changes in
horsepower settings.
Work Safely: Always wear eye protection and gloves when working with lines or hoses that contain
pressurized nitrous oxide or fuel. Never transport nitrous cylinders loose in a trunk or the back of a pick-up truck
and especially NOT within a vehicle's interior whether the cylinder is full OR empty. Always disconnect the
GROUND side of the battery when working on any electrical components.
Nitrous Oxide won't fix problems you already have: Before you install your nitrous system, be sure
your engine is in good mechanical condition. Intermittent wiring problems, etc., can lead to erratic system
performance and possible engine damage.
Never defeat operation of the safety relief disc in the nitrous cylinder's valve: It's required by
law and is there for your safety. Never drill, machine, weld, deform, scratch, drop, or modify a nitrous oxide tank
in ANY way whatsoever!
Never overfill nitrous cylinders: That little bit extra will put you and others at risk of injury. More often
than not, when the cylinder warms up, the pressure goes above the limit of the safety relief disc and you lose all
the nitrous you just paid for.
