Spark Plugs

Refine Results

There are a number of different parts that make up the ignition system in your Subaru. The spark plugs are electrical parts that fit in your vehicle's cylinder heads that are located in the internal combustion engine. The spark plugs are small parts, but they are very important. They contain electrodes that are connected from a wire to your ignition coils. Electrons flow from the coil that will eventually produce an electric spark that gets the combustion process going. This helps to start your engine. It's important that you pay attention to the condition of your spark plugs. Even just one faulty spark plug can cause issues with the way your vehicle is running. Your vehicle's engine might start to experience a range of issues if your spark plugs are wearing down. The engine can have decreased performance, which can eventually cause your check engine light to come on. Weakened spark plugs can also cause your vehicle's engine to have a harder time starting in general. It can start to misfire. It might even idle roughly. If you find you need replacement spark plugs, ensure you get ones that are made for your car. Find OEM Subaru spark plugs and ignition components here on our site.
