Ignition Coil buying guide

Why replace this part?

Ignition coils transform battery voltage into the high voltage needed to create a spark at the spark plug. A failing coil causes misfires, rough running, and can damage the catalytic converter if left unaddressed.

Signs you need a replacement

  • Engine misfires
  • rough idle
  • loss of power
  • poor fuel economy
  • check engine light with misfire diagnostic codes
  • difficulty starting

When to replace

No fixed interval — replace when symptoms or diagnostic codes indicate failure. Some mechanics recommend replacing all coils together.

Installation difficulty:Moderate — requires basic tools and mechanical knowledge
