ZEX™ Dry Nitrous Systems for LT1 applications incorporate patented Active Fuel Control™ technology, which monitors the nitrous bottle pressure and automatically adjusts fuel enrichment to achieve the perfect mixture. This ensures your engine will never run too rich or too lean when you engage the nitrous system. ZEX™ nitrous activates at wide open throttle using an electronic switch that monitors your engine’s TPS sensor. The design ensures that your nitrous is engaged at the perfect wide open throttle position every time for maximum power and safety. The ZEX™ LT1 Dry Nitrous System is designed to be a simple and easy, 2 hour installation – all major components are factory pre-assembled inside the Nitrous Management Unit. This system will work safely on both stock and high performance, normally aspirated engines.
