Where are the spark plugs located on a Ford Mustang GT 4.6L V8?
The spark plugs on a Ford Mustang GT 4.6L V8 are located on the top of the engine, between the valve covers. You'll need to remove the valve covers to access them. They're arranged in a V-shape, mirroring the cylinder arrangement of the engine. Specific location on each cylinder will vary slightly depending on the year of the Mustang. A shop manual or online diagrams specific to your year would be helpful for exact placement.
