Importance of Spark Plugs 

Spark plugs move high voltage current from the ignition coil to ignite the combustion chamber when you start your car. If they don't work correctly, you will notice your car having issues with performing at its best on the Bartlett roads. Some issues include: 

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

Not to mention, when these issues happen, you and your passenger's safety are in jeopardy as well, so you want to make sure you are replacing the spark plugs when they need to be!
