What does an ignition coil do?

An ignition coil's job is to convert the battery's low voltage into the high voltage needed to create a spark at the spark plug. This spark ignites the fuel-air mixture in the engine's cylinders, making the engine run.

How do I know if my ignition coil needs replacing?

Common signs of a failing ignition coil include engine misfires, rough idling, poor acceleration, decreased fuel economy, and a check engine light. If you notice these symptoms, it's a good idea to have your ignition system checked.

Does this ignition coil come with everything needed for installation?

This ignition coil is sold individually and is designed as a direct replacement. You will typically reuse your existing mounting hardware and wiring connector. Always refer to the manufacturer's installation instructions for specific details.
