What Are the Benefits of Replacing Spark Plugs?

Before we can discuss the various benefits of swapping out your old spark plugs for new ones, you should probably know what spark plugs do. Spark plugs are little metal pieces that allow the spark of electricity to ignite the combustion process needed to start your vehicle. Your spark plugs keep your car powered while providing a smooth and balanced air-fuel mixture by putting the engine's pistons to work. Because spark plug health is directly correlated to engine performance, you can imagine that you can't go anywhere without them, at least not efficiently.


If your spark plugs are due for a replacement, please do not neglect them. The primary benefit of getting this service is knowing your car will start without a hitch. Needless to say, that's not all that you can get out of a spark plug replacement. New and fresh spark plugs provide other advantages as well.

  • Consistent production of optimal combustion. Fully functioning spark plugs will yield a fully functioning combustion process. Once you achieve this process with your new pieces, you can say goodbye to all the performance issues you were experiencing before.
  • Smooth starts. The first time you switch the ignition on with a new spark plug can be an eye-opening experience. You won't have to deal with jerky or difficult starts anymore.
  • Boost in fuel economy. The National Institute for Automotive Service Excellence claims that misfiring spark plugs can lessen fuel efficiency by 30 percent. When replaced at the correct intervals, new plugs can maximize your fuel economy and save you some coin in the long run.
  • Less harmful emissions. The Environmental Protection Agency states that regular vehicle tune-ups, especially regarding spark plug replacement, also reduce air pollution. That's a win-win for you, your car, and the environment.
