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.
