OEM Ford Spark Plugs

Although tiny, spark plugs are mighty. They help in transmitting electric current from your car’s ignition system to its spark-ignition engine’s combustion chamber. Once there, the electric spark ignites the compressed air/fuel mixture, causing your motor vehicle to start. Many auto manufacturers and experts recommend that you replace spark plugs after every 20,000-40,000 miles. However, you can consider replacing them if you notice certain changes, including difficulty starting your car, misfiring engine, poor fuel economy, and slow acceleration, and poor vehicle performance.
