ZEX™ Add-A-Stage Nitrous System –Add 50-250 Hp To Your Existing Shot*!

The ZEX™ Add-A-Stage Nitrous System upgrades any single stage EFI nitrous kit to a two stage system. A two stage system runs faster than a single stage system because it gradually adds the nitrous power in two separately controlled stages instead of one big, tire spinning hit. The Add-A-Stage Nitrous System is operated by a push button switch for ease of control, and jets are included for adding an extra 50-250 horsepower. The Add-A-Stage Nitrous System incorporates the same great nitrous technology breakthroughs as the other ZEX™ nitrous systems –ensuring that your nitrous/fuel mixture stays precisely balanced throughout your run.

*Note bottle valve in a single-bottle ZEX™ nitrous system can support up to 300 HP only.
