Spark plug location
Where are the spark plugs located on a 2001 F150 with the 5.4 Triton. Sounds like a dumb question but I told him (my friend) I'd have the answer rather quickly on this awesome site I know. Thanks,

The spark plugs are usually in the engine!
Unless you're really unluck and blew them all out, the plugs are under the coil on plug (COP) modules. If you look on top of the engine by the fuel rails you'll see 4 COP's on each side, the plugs are under there (no more distributor and wires on these engines)
If you need to change them search the tech articles, there are step by step instuctions, but it's kind of a tough job

Triton and Blue Oval,
Thanks for the fast responses. I printed them out and gave the info to my friend, another GySgt in the USMC. I only have a PSD Crew Cab so spark plugs aren't an issue, looks like a good thing, too! I told him to start his own profile already
