ZEX Nitrous offers both Wet and Dry Nitrous Nozzles that can be used for any custom installation; great for direct-port or single nozzle nitrous installations. Wet Nozzles use patent pending Fuel Shear technology that creates complete atomization by placing enrichment fuel directly inside the nitrous plume exiting the nozzle. Dry Nozzles are designed to perfectly disperse nitrous into the air inlet of the engine, eliminating lean cylinders for maximum safety and performance.
