New advanced system safely adds 75-125 hp to popular 2005 & newer Hemi engine applications

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 a 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 kit's fuel enrichment so you are never too rich or too lean.

ZEX engineers always keep safety in mind when designing their products; the ZEX-patented electronic TPS switch is a case in point. Another ZEX exclusive, the throttle position sensor feature ensures that the nitrous oxide system activates only at wide open throttle, making sure that the nitrous shot is introduced only at the best possible moment.
