Used ZEX Nitrous Kit. 

I purchased this unit over 10 years ago to use with a car project I had at the time. Things changed and I ended up never installing it. The unit was used when I purchased it, and did not include the bottle, which is still not included. 

What is included; ZEX control unit, all the jets for different HP shots, braided steel lines, rubber hoses with connectors, dry injection nozzle, and activation switch. 

Here is the unit description from Summit Racing for the same model number: 

Description: ZEX dry nitrous systems feature an "Active Fuel Control" that reads bottle pressure and adjusts fuel enrichment to provide optimum power safely at all bottle pressures. In addition, their exclusive throttle-position sensor switch "learns" the voltage curve of the engine's throttle position sensor to activate the system at wide-open throttle every time. ZEX systems come pre-assembled and tested, so you know that they'll work right out of the box. You can install them quickly--there are no brackets to install or microswitches to adjust--and jet changes are simple.

Add the bottle and bracket, install and go!!

As I stated I never installed the unit, and am unaware if it is functioning. I have no reason to believe it wouldn't be, it has been sitting inside my home, in the box since I received it. 

I am a private seller, not a store, and will be happy to answer any questions to the best of my ability. Thank you for looking, and happy bidding!
