New Engineered Nozzle Options

Available in 50 or 100 HP options, the engineered nozzles are brand new units manufactured with the highest of quality & control standards to their specified size. These are not simply stock nozzles that have been media honed! Specifically designed with a modified spray pattern and manufactured to size, these nozzles are engineered for better fuel atomization which leads to improved in-cylinder flame propagation.
