Uniform fuel distribution reduces vibrations caused by uneven combustion,this results in a quieter idle, less engine chatter at highway speeds, and a more refined driving exPerience overall,the reduced mechanical stress also extends the life of engine mounts and other components. By delivering fuel precisely at the optimal moment, these injectors create a stronger, more consistent explosion in each cylinder. Fuel Injector Failure Can Cause: Abnormal engine vibration, reduced power, increased fuel consumption, abnormal exhaust emissions, difficulty in starting the engine or engine stalling while the vehicle is driving. The fuel injector is designed for optimal fuel atomization oil mist, promoting smooth engine operation and balanced fuel delivery, reducing overall fuel consumption., Manufacturer: YUCHUJCGSS
