Spark Plugs

The spark plugs in your Ford are a critical part of the ignition system. They work as a part of the internal combustion engine to help get your car to start. They generate a spark that ignites an air and fuel mixture inside the combustion chamber, and your car requires a particular type of spark plugs that work with the rest of the ignition parts. These are parts that like oil filters or air filters, require routine maintenance so that your car engine can run as efficiently as possible. It's important to pay attention to any signs that your spark plugs are wearing out. These can include:

- Slower acceleration. If you find that your car is taking longer to accelerate than it used to or running a big sluggish, the most common cause is something within the ignition system. When your spark plug materials wear out, the effectiveness wears out, which means the process of accelerating becomes harder for your car to complete.

- Reduced fuel economy. Spark plugs running correctly means that your car is burning fuel efficiently. Poorly performing plugs can cause a decrease in efficiency, which means it might be burning fuel faster than it used to.

These are just a few symptoms that the spark plugs in your Ford might need replacement. It's key to grab a set of OEM plugs when you need new ones so that you can get parts that fit your make and model. Find them here at Ford Genuine Auto Parts.
