For ford for Fiat,Material:plastic+Metal The injector has better atomization function, which can achieve precise injection, fuel saving and environmental protection. Stable performance, high reliability.a perfect replacement for your old ones. Optimized fuel atomization improves combustion efficiency, reduces hydrocarbon and carbon monoxide emissions, and aids in vehicle emissions testing without requiring major overhauls. Low-pressure atomization can prevent the air-fuel mixture from being too rich during low-speed traffic jams and effectively reduce carbon deposits in the cylinders during frequent start-stop driving., Manufacturer: NMJLQW
