Where are the spark plugs on a 2001 Ford F150 super crew with 5.4L V8?

The spark plugs on a 2001 Ford F-150 SuperCrew with the 5.4L V8 are located on the top of the engine, between the valve covers. Because it's a V8, they're arranged in two rows, one on each side of the engine valley. You'll need to remove parts of the engine's top cover to access them. This often involves removing various components like:

* Intake Manifold: This is a significant undertaking and often requires removing various vacuum lines and sensors first.

* Ignition Coils: These are typically bolted onto the valve covers directly above the spark plugs and must be removed to access the plugs themselves.

Important Note: Accessing the spark plugs on this engine is a moderately involved job and requires some mechanical aptitude. Consult a repair manual specific to your vehicle's year and engine for detailed instructions, diagrams, and torque specifications. Incorrectly installing spark plugs can cause damage to your engine. If you're not comfortable performing this task yourself, it's best to take your truck to a qualified mechanic.
