How Often to Change Your Spark Plugs

Eventually, diligent Apex car owners will need to ask, “When do I change spark plugs?” Auto experts generally recommend spark plug replacement every 30,000 miles, but the figure may vary depending on your particular vehicle. For an exact number, check your owner’s manual. In the meantime, you can find more information about how often to change spark plugs with the Hendrick Dodge Cary service pros!

When Do I Change Spark Plugs?

First things first: what do spark plugs do? As an essential component of your transmission, the spark plugs work by moving the high voltage current from the ignition coil to the combustion chamber each time you start your car up in Carrboro. How will you know when to change spark plugs? Here are some common warning signs to watch out for:

  • Slow or no start when you turn on the ignition
  • Engine misfire
  • The engine is running rough
  • Rough idling
  • Poor acceleration
  • Poor gas mileage

Why Do You Need to Change the Spark Plugs?

If you’re experiencing one or more of the issues we listed above, replacing the spark plugs will fix them and give you an efficient, comfortable ride once more. Changing your spark plugs at regular, on-time intervals provides the following benefits:

  • Smooth Start – Replacing spark plugs ensures a smooth start every time you turn the ignition in Chapel Hill, so there’s no more frustration when you’re running late for work.
  • Better Fuel-Efficiency – All drivers want their car to reach its full potential for fuel-efficiency, and replacing your spark plugs regularly can help achieve this. Worn spark plugs can actually reduce your fuel economy by up to 30%! Not to mention, your emissions are cleaner when you have new spark plugs.
  • Dependable Combustion System – Spark plugs enable the continuous production of combustion, helping to prevent backfiring and rattling.
