Frequently Asked Questions

What is the difference between an ignition coil and a spark plug?

The ignition coil transforms the vehicle's low battery voltage into the thousands of volts needed to create a spark. The spark plug receives this high voltage and uses it to ignite the air-fuel mixture in the combustion chamber.

How do I know if my ignition coil is failing?

Common symptoms of a failing ignition coil include engine misfires (rough idling or stuttering during acceleration), poor fuel economy, the 'Check Engine' light illuminating, and difficulty starting the engine.

Are bulk ignition key packs compatible with all heavy equipment?

No. While some keys (like the Kubota or Bobcat keys listed) cover a wide range of models from that specific manufacturer, they are not universal. Always match the key's part number (e.g., 6709527) to your equipment's required key code.

What does an ignition lock cylinder do?

The ignition lock cylinder is the mechanical part where you insert your key. It controls the electrical flow to the ignition switch, allowing you to turn the vehicle on, off, or to the accessory position, and also provides steering column security.

Final Thoughts

Replacing faulty ignition components is a straightforward way to restore your vehicle’s performance, reliability, and security. By selecting high-quality parts from this list—whether you need a full coil and spark plug kit for a Ford Super Duty or a lock cylinder for a classic GM—you can be confident in your engine's ability to start and run smoothly.
