What is the safest way to activate a nitrous system?
The safest way to activate a nitrous system is by using a wide-open throttle switch. All ZEX™ nitrous systems utilize this type of activation. Activating a nitrous system at anything less than wide-open throttle can greatly increase your chances for an intake system backfire. If you desire to use a push button (part #NS 6534) for activation, ZEX™ offers this as an accessory item. You can simply install the push button inline with the wide-open throttle switch.
