How Often to Change Your Spark Plugs

If you’re wondering how often to change your spark plugs, you’re not alone. Many experts maintain that the answer to “when do I change spark plugs?” should be every 30,000 miles, but this might not be the case for your particular make and model. The best place to start is in your owner’s manual, where you should find the manufacturer’s recommendation for how often to change spark plugs. In the meantime, the East Bay BMW service pros are here to provide helpful information regarding spark plugs.

When Do I Change Spark Plugs?

The spark plugs are a component of your vehicle’s ignition system. Their primary function is carrying high voltage current from the ignition coil to ignite the combustion chamber. This process happens every time you start your vehicle in San Francisco. Should your spark plugs need attention, you might find that the performance of your vehicle is taking a hit. Here are the warning signs to look for:

  • Struggling to start or not starting at all
  • The engine is running poorly
  • Noisy, rough idling
  • Increase in fuel consumption
  • Slow acceleration
  • Engine misfire

Why Change the Spark Plugs in Your Car?

You certainly want to avoid any of the issues listed in the aforementioned warning signs of bad spark plugs. This is reason enough to change your spark plugs when necessary, but there are some other benefits worth considering:

  • Maintaining good fuel economy – With worn-out spark plugs, your fuel economy can decrease by as much as 30%! Maintain efficiency on San Jose roads by replacing the spark plugs when you need to.
  • Reliable combustion system – Spark plugs that are in good condition will provide reliable and continuous production of combustion, so your vehicle’s system runs without a hitch.
  • Struggle-free startups – When you’re leaving for work in the morning, the last thing you want is to struggle to start your car. Maintaining the spark plugs ensures a clean start every time you turn the ignition.
  • Improved emissions – Healthy spark plugs lead to healthier vehicle emissions!
