Frequently Asked Questions

Q: What does an ignition coil and spark plug wire set do? A: The ignition coils step up battery voltage to the high voltage needed to produce spark, and the spark plug wires deliver that voltage to each spark plug so the engine can ignite its air-fuel mixture.

Q: How should I verify fitment? A: Compare the existing ignition coil and wire part numbers and the complete engine model and displacement designation against the information in the listing before ordering.
