Good To Know

Q: How do I know if my ignition coil has failed? A: Common signs include a no-start condition, misfiring, rough running, or a weak spark when the plug is tested against the engine block.

Q: Should I replace the spark plugs at the same time? A: Replacing plugs and checking the plug wires while the ignition coil is being serviced is a practical step that helps confirm a complete spark path.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
