The Dodge 5.7L and 6.1L EFI Hemi engines are the perfect platform for nitrous injection upgrades. The ZEX™ Blackout 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.

Systems feature all-new black powder-coated bottles, carbon-fiber look hoses, plates and fittings that are perfect for street/strip and all-out drag racing applications. The perfect combination of great looks and serious adjustable boost from 75 to 125 horsepower, this ZEX™ Blackout Nitrous System™ contains patented ZEX™ features, including Active Fuel Control™ and a throttle-by-wire compatible electronic TPS switch.
