The Dodge 5.7L and 6.1L EFI Hemi engines are the perfect platform for nitrous injection upgrades. The ZEX™ nitrous system for the new Dodge Hemi Challenger was extensively engineered for a simple plug and play installation and includes custom-designed brackets and a special fuel line adapter that helps you finish the installation in only 2-3 hours.

For the ultimate in engine safety, the ZEX™ kit 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.

The ZEX™-patented electronic TPS switch is another example of safe engineering. A ZEX™ exclusive, the throttle position activation feature engages the nitrous only at wide-open throttle using your accelerator pedal. This technology not only makes it easy for you to activate the nitrous, but it is fully compatible with the Challenger’s throttle-by-wire engine.
