* Engine Variations: The recommended spark plug gap can vary slightly depending on the exact engine configuration, including the type of spark plugs installed (platinum, iridium, etc.).
* Owner's Manual is Key: The most accurate information will be in your Ford 5.8 engine's owner's manual. It will have the specific spark plug gap for your vehicle.
* Consult a Mechanic: If you don't have your owner's manual, a qualified mechanic at a local shop can easily look up the recommended gap using their resources.
General Spark Plug Gap Information:
* Typical Range: Spark plug gaps are usually between 0.035" and 0.050".
* Too Wide: A gap that is too wide can cause misfires, as it is harder for the spark to jump across the gap.
* Too Narrow: A gap that is too narrow can result in reduced performance and fuel efficiency.
Remember: Always use the correct spark plug gap for your engine to ensure optimal performance and longevity.
