Spark Plugs
Keeping your Ford’s ignition system in top shape is essential for smooth and reliable performance. This system is responsible for starting your vehicle and keeping it powered while you’re on the road. It’s made up of several critical components, including the starter motor, ignition coils, and spark plugs.
Though small in size, spark plugs play a major role in your ignition system. They generate the necessary spark to ignite the air-fuel mixture in your engine’s combustion chamber, ensuring efficient engine performance. Over time, spark plugs can become worn out or damaged, which may lead to engine misfires, rough idling, or trouble starting your car.
If you notice any of these issues, it’s crucial to inspect your spark plugs and replace them if needed. Using OEM spark plugs ensures a perfect fit and optimal performance for your Ford vehicle. OEM parts are designed specifically for your model, providing the reliability and durability you need.
