Spark plugs are a critical part of your vehicle's engine. Spark plugs ignite the fuel and air mixture in your engine to create combustion. Spark plugs can tell you a lot about your engines health and also need to be replaced from time to time as they do eventually wear out or can become damaged. Worn out or damaged spark plugs can cause bad fuel economy, lack of power, and engines to run rough. Generally spark plugs should be replaced every 75,000 to 100,000 miles. If your vehicle is close to 100,000, or 200,000 miles you might wanna think about getting your spark plugs replaced.
