This air shifter kit is complete in all respects. It contains EVERYTHING you need to add "button" shifting to your ZX-14. Incorporating a high pressure gas bottle you have up to 800 shifts between fills. Unlike other kits there is nothing else needed to install or use. All wiring is contained in an OEM quality plug-in loom and all components are of the highest quality.
Your horn button becomes a selectable shift button that easily turns the system on or off and shift kill time is adjustable via the MUZZYS Digi-Kill 3® Power Interrupt.
The Digi-Kill 3® matches the kill time to coincide with the actual movement of the shift linkage. Momentarily stopping fuel delivery instead of killing the ignition results in smoother power interruption and less backfiring. Double shifting due to “button bounce” is eliminated and repeats the same sequence regardless of how long the button is held.
MUZZYS Air Shifter Kit with Digi-Kill 3® requires no drilling or machining. The mounting brackets are machined from billet aluminum and all necessary hardware is included.
It's upgradeable too! Add the Muzzy Nitrous upgrade kit at any time for a simple plug and play addition to the Air Shifter Kit.

Want the Muzzy Dry Nitrous Kit too? Muzzys has two options available. Purchase the Dual Air/Nitrous Kit and save $290! Or buy the Air Shifter Kit now and purchase the Nitrous upgrade later. The wiring harnesses are 100% compatible. When the Dual kit, is installed, the horn button activates the Air Shifter while the starter button activates the Nitrous. It couldn't be simpler. Just remember to hang on!

*Air shifter and dry nitrous kits are not compatible with the stock ZX-14 exhaust.
