How Often to Change Your Spark Plugs

It only takes a spark to start a fire, and in the case of internal combustion, which relies on the burning of gasoline within a controlled and pressurized environment (inside the engine’s pistons), sparks are created by spark plugs! But these critical components, like many automotive parts, eventually wear out. So, if you’re asking yourself “when do I change my spark plugs?” or how often it’s necessary to swap out your spark plugs, we have the answer! Typically, experts recommend replacing a car’s spark plugs roughly every 30,000 miles. But you can consult your owner’s manual to learn more, or contact us at Rusnak/Pasadena Porsche!



When Do I Change Spark Plugs?

The spark plugs in your car are part of the ignition system that moves high voltage current from the ignition coil to start the internal combustion process when you start your vehicle. When your car’s spark plugs need replacing, you may experience one or more of the following on your drives around Los Angeles:

  • Engine misfire
  • Slow or no start
  • Engine runs rough
  • Poor acceleration
  • Rough idling
  • High fuel consumption

Perks of Changing Your Spark Plugs Often

Changing your spark plugs regularly not only helps you avoid issues, but can also even have some inherent benefits. Here’s what you’ll enjoy when you make changing spark plugs part of your preventative maintenance routine:

  • Increased fuel economy – While worn-out spark plugs can reduce your fuel economy by as much as 30%, replacing them can get you back into the normal range again.
  • Consistent combustion – Spark plugs ensure that consistent combustion takes place, making sure your vehicle operates as smoothly as possible.
  • Smoother starts – When you replace old spark plugs, you’ll probably notice that it’s much easier to start your engine.
  • Less harmful emissions – Improving emissions is yet another advantage of replacing your car’s spark plugs.
