Chrysler's late model Hemi engines are the perfect platform for nitrous injection upgrades. The Zex Charger/Magnum Nitrous System comes factory pre-assembled, making for simple and easy, plug and play installation (two hours from start to finish).

For the ultimate in safety, the Zex kit also uses an advanced safety technology called Active Fuel Control. This exclusive Zex technology monitors the nitrous bottle pressure and adjusts the kits fuel enrichment so you are never too rich or too lean. Zex engineers always keep safety in mind, and the Zex patentes electronic TPS switch is a case in point. This feature ensures that the system only activates at wide open throttle.
