ZEX Nitrous System Kits for Dodge/Chrysler applications are extensively engineered for a simple plug and play installation and include custom-designed brackets and a special fuel line adapter that helps you finish the installation in only 2-3 hours. For the ultimate safety, an advanced safety technology called Active Fuel Control monitors the nitrous bottle pressure and adjusts the kit's fuel enrichment so you are never too rich or too lean. A ZEX-patented electronic TPS switch 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 throttle-by-wire engines.
