How Often to Replace Spark Plugs

Your spark plugs work by moving the high voltage current from your vehicle’s ignition coil to ignite the combustion chamber when you start your car. They are a crucial part of your vehicle’s components. If the spark plugs aren’t functioning correctly, you’ll begin to experience some problems in vehicle performance, such as: 

  • Poor acceleration
  • Slow start or won’t start at all
  • Engine misfiring
  • Engine running rough
  • Inconsistent idling
  • Poor fuel economy
  • And more

Benefits of Spark Plug Replacement

In addition to avoiding the unpleasant issues above, these are several other benefits that come from regular spark plug replacement when driving around Princeton:

  • Better fuel economy – Worn-out spark plug may decrease your fuel economy on Hamilton roads by up to 30%!
  • Consistent combustion system – Spark plugs provide constant production of combustion and leave your car’s system running at maximum efficiency.
  • Your Vehicle Starts Easily – With spark plug replacement, your vehicle will effortlessly start when you turn the key in the ignition.
