How to replace spark plugs for your specific vehicle

Do you ever think of your spark plugs as the heart of your engine? The primary purpose of the spark plug is to ignite the air fuel mixture inside the cylinder, so your car's engine can make power. The secondary function is to transfer the heat generated by that process into the surrounding engine coolant that flows through the cylinder head. This transfer keeps the spark plugs self-cleaning and the rate at which the plugs transfer heat is called the heat range.
