The multi-micro-hole swirl nozzle produces a fine and uniform spray pattern, resulting in minimal idle vibration and lower noise levels during heavy-load towing by American pickup trucks, domestic urban freight transport, and agricultural machinery operations in the fields. It fully complies with North American, China’s National III, and Euro III emissions standards.
