Spark Plugs

Refine Results

For your engine to start efficiently, having your spark plugs in good health is where you should start. They create the ignition necessary for your car to start by sending electricity to spark the air-fuel mixture. Spark plugs last between 60,000 to 80,000 miles, but they can wear out sooner, so it's crucial to know the warning signs. Things like rough idling, difficulty turning over, reduced horsepower or lower fuel economy, are some of the primary indicators. There are four types of spark plugs, copper, iridium, platinum, and double platinum. Iridium, platinum, and double platinum last the longest, sometimes over 100,000 miles. Spark plugs are a maintenance item and are usually involved in a scheduled tune-up. Ignoring your spark plugs can quickly leave you stranded on the side of the road, which is never fun. Don't wait for problems to escalate. Instead, do your engine a favor and replace them with genuine factory parts at the first signs of an issue. At GM Outlet Parts, we take pride in providing exceptional customer service, one of the reasons many consider us their top choice for all things automotive. Complete your order online today and have your items sent directly to your door, anywhere nationwide.
