Spark Plugs

Refine Results

Faulty spark plugs are something that can cause it to be difficult to get your Subaru started. While starting issues can stem from a range of ignition system parts, it's worth checking out the spark plugs. They might be small parts of the system, but they have the responsibility of delivering the spark that is needed for your engine to be able to rev. There is a mix of air and fuel in your car's combustion chamber that relies on a spark for the process to take place. Spark plugs are also responsible fro helping get rid of the heat that is produced in these spaces. Your spark plugs are built to handle large amounts of heat and frequent use, but they are parts that can wear out just like any other component in your vehicle. Failing spark plugs might not produce the right amount of electricity for your car to be able to start properly. If your car is taking more of an effort to start, your spark plugs could be failing. You could also notice things like a drop in fuel economy. Make sure that you invest in high quality spark plugs when you need to make replacements. We sell OEM spark plugs here on our site.
