Slower acceleration speed is a common indicator that your spark plugs need changing. Doing it yourself at home requires the proper tools and some spare time, but overall the process is relatively easy! If you’re up to the task, here’s what you’ll need:
  • Ratcheting socket wrench
  • Torque wrench
  • Socket wrench extension
  • 14 mm spark plug socket
  • Spark plug gap tool
  • Vacuum or compressed air blower
  • Clean rags or towels
And, of course, your new spark plugs.
Before you begin, park your car somewhere you have room to work, turn it off and remove the keys. You’ll also want to disconnect your car’s negative battery terminal.
To change the spark plugs, here’s what you’ll do:
  • Start by removing the plastic engine cover. You’ll need your 10 mm socket to loosen the bolts
  • Set your engine cover aside and put the loose bolts in a safe place for later
  • Use your vacuum or compressed air blower to clean out any dirt or debris from the area around your spark plugs
  • Remove the spark plug boots, one at a time
  • Remove the ignition coil from the spark plug well and set it aside
  • Attach your 14 mm spark plug socket to the extension bar, and loosen the old spark plug by turning it counterclockwise
  • Use your spark plug gap tool or your socket wrench extension to insert and gently thread the new spark plugs into the spark plug well
  • Use the torque wrench to tighten your spark plugs as necessary
  • Reattach the spark plug boots
  • Reconnect your battery
Congratulations! You’ve changed your spark plugs yourself!
