ZEX wet nitrous systems rely on advanced fuel-shear technology that places the enrichment fuel inside of the high-velocity nitrous spray cone via a special transfer tube. This ensures complete fuel atomization and maximum power. In addition, ZEX's exclusive throttle-position sensor switch "learns" the voltage curve of the engine's throttle-position sensor to activate the system consistently at full throttle. ZEX systems come pre-assembled and tested, for easy installation. There are no brackets to install or microswitches to adjust, and jet changes are easy, too.
