What It Helps Address

• Engine misfire caused by weak ignition output
• Rough idle related to inconsistent spark delivery
• Hard starting tied to ignition coil wear
• Loss of power from intermittent coil performance
• Check engine light conditions associated with ignition faults

Installation Notes and Tips

Verify the year, model, and application notes before ordering. Confirm whether your vehicle listing calls for boot and spring inclusion or exclusion, since the fitment notes differ by model year. Match the connector and mounting location to the original coil before installation, and inspect adjacent ignition components during service.
