It is very important to note that you should always consult your owner's manual or a reliable repair manual for the specific gap recommendation for your vehicle.
Here's why checking the owner's manual is essential:
* Engine variations: There might be slight variations in the recommended spark plug gap depending on the specific engine configuration or year of your Thunderbird.
* Spark plug type: The recommended gap can also vary depending on the type of spark plug you're using.
By checking the owner's manual, you'll ensure you're using the correct spark plug gap for optimal engine performance and longevity.
