Frequently Asked Questions

Q: Will this coil pack fix a misfire and check engine light? A: Yes, if worn ignition coils are the cause, installing this set restores consistent spark delivery, eliminating misfires and associated trouble codes.

Q: Should I replace all six coils at once? A: Replacing all six coils ensures uniform performance and prevents a single aged coil from causing future misfires, which can damage the catalytic converter.
