Spark Plugs

So how often should spark plugs be replaced? A common question for many vehicle owners is “When should I change my spark plugs?” Well, not all spark plugs are rated for 100,000 miles. In fact, some carmakers recommend replacement at 30,000-mile intervals. So always follow the spark plug service intervals shown in your owner’s manual to figure out when to replace spark plugs. But if you can’t remember when you last changed your spark plugs, you can pull them and check the gap and their condition. Once you’ve put in the labor to begin checking spark plugs, however, you may as well change them and establish a new baseline for the future. Learn how to buy spark plugs so you get the job done right.
