GM Spark Plugs
There are many different parts in your vehicle that make up the ignition system, and your spark plugs are one of them. The spark plugs might be on the smaller side, but that doesn't mean they aren't important! Spark plugs are devices that produce electric sparks to ignite the compressed fuel/air mixture in the combustion chamber and start the vehicle. They are necessary for the combustion process to take place. Faulty spark plugs can cause several issues when it comes to the performance of your GM vehicle. These things can include trouble starting the car, poor fuel economy, slow acceleration, uneven idling, and engine misfiring. If the check engine light comes on, it may indicate that a spark plug is faulty. Even just one spark plug being worn out can cause issues with the performance of your vehicle. When a spark plug needs to be replaced, never settle for aftermarket parts. Always choose genuine OEM spark plugs to get the best value for your money. OEM spark plugs have quality guarantees and are manufactured consistently with high quality materials. Find replacement spark plugs for your GM here on our site and keep it running smoothly.
