Spark plugs provide power to your engine, making them one of the most important parts of your car.
Because of their significance in a car’s overall function, you should check your spark plugs’ condition from time to time. Ideally, your spark plugs should be replaced every 80,000 miles, or as directed in your owner’s manual.
Do not run your engine while inspecting your spark plugs. Instead, let your engine cool down first.
Clean the spark plug area first before removing them. For better results, use an air compressor to get rid of any debris or dirt around the spark plug area.
Using a socket that fits the spark plugs, loosen and unscrew the rest of the spark plugs and then take them out from the engine. Check for any burns, cracks or damages such as a cracked insulator, damaged gasket or damaged electrode.
If there’s no damage on your spark plugs, put them back in their cylinders, screw them back in by hand and seal them tight using a socket wrench. Otherwise, you should find out what spark plugs are recommended for your car.
When in doubt, have your vehicle serviced by a knowledgeable mechanic.
