Spark plugs have a big job to do. Small but mighty, they power up your vehicle, keep it powered up and produce a smooth burn of the compressed air-fuel mixture. Spark plugs fire constantly and wear down over driving time, reducing their efficiency. Replacing them can greatly improve your engine’s performance and can be done at home with basic hand tools.

In our new video, Greg will show you how exactly you can perform this installation. He is using Motorcraft spark plugs for the 2010 Ford Expedition equipped with the 5.4l V8 engine. Learn how to replace the spark plugs at home with CARiD!
