While your vehicle’s engine runs on gasoline, it needs electricity to run, and spark plugs create arcs of power for your engine to turn. Hence, they are vital parts of your car because they connect wires that lead to the ignition system.
Therefore, replacing your spark plugs is essential in ensuring your engine functions correctly and smoothly. Experts recommend replacing your spark plugs every 30,000 miles. You can also check your owner’s manual to find the recommended timeline from your automaker.
However, how often you replace your spark plugs depends on different factors like performance, durability, and oil leaks. For instance, copper spark plugs are less durable and need replacement after every 20,000 miles.
