ZEX™ Ejector Air Amplifier (patent pending) is the first air induction system to harness the kinetic energy of compressed nitrous oxide. It easily installs in place of your standard cone air filter and connects to any manufacturers dry nitrous system. As the high-speed nitrous gas exits the nozzle in the end of the filter, the stream "captures" the surrounding air and induces a significant increase in airflow. Tests show increases of 50 cfm with just a 75 hp shot of nitrous. The other great benefit of the "Ejector" is that it greatly simplifies a dry nitrous kit installation. You don’t have to drill and tap your intake tube for a standard nozzle, simply slide the ZEX™ Ejector Air Amplifier in place of your standard cone filter and your ready to spray. The "Ejector" design has been incorporated into a race-quality air filter that is both washable and reusable, for years of superior performance.
