How Often to Change Your Spark Plugs

Spark Plug Black Background

Knowing how often to change your spark plugs will help your Mercedes-Benz car or SUV perform exactly as its makers intended. Your spark plugs, after all, are responsible for moving current from the ignition coil to the combustion chamber, and that means they’re responsible for everything from engine start-up to acceleration! In general, a replacement interval of roughly 30,000 miles will be more than sufficient to keep you moving forward.

When Do I Change Spark Plugs?

If your spark plugs are working properly, you probably won’t give them much thought as you drive around Mayfield and Cleveland. However, once they start to go bad, the effects are hard to miss. If you’ve experienced any of the following, there’s a good chance it’s time to schedule service:

  • Slow engine start-up, or failure to ignite
  • A misfiring engine, or an engine that’s running loud
  • Rough, noisy idling or unsatisfying acceleration
  • Higher-than-average fuel consumption

Since no two vehicles are exactly alike, you’ll want to check your owner’s manual to get a precise answer to the question, “When do I change spark plugs?”

Benefits of Changing Your Spark Plugs

Newer spark plugs work better than those that are reaching the ends of their lives, and choosing OEM parts over aftermarket alternatives is always a good idea. That’s another way of saying that you’ll experience many different benefits when you know how often to change your spark plugs and get the job done at Mercedes-Benz of Bedford:

  • Improved Fuel Economy – Replacing old, worn-down spark plugs with fresh ones can improve your fuel economy by up to 30%, back to original factory-fresh levels.
  • Instant Start-Ups – Your time behind the wheel of a Mercedes-Benz should be satisfying from start to finish. With fresh spark plugs, start-ups are effortlessly smooth.
  • Cleaner Emissions – Improving your vehicle’s performance really can go hand-in-hand with care for the environment! New spark plugs burn fuel more cleanly and completely.
  • Responsive Acceleration – Pressing on the gas pedal should generate an instantaneous response! Replacing your spark plugs can instantly improve your vehicle’s acceleration on Beachwood-area highways.
