Which plugs for 99 5.4?

It's time for a tune up on my 99 with a 5.4. Which spark plugs do you guys recommend? Looking at parts stores online, it looks like there are plenty of choices. Just curious what you guys run. Also, would you guys recommend replacing the COP's as well? The truck has 150,xxx miles on it.

Sorry I didn't use the search first. I'm at work and have limited time on here.

You will not go wrong replacing the COP's. Here is the link to what is generally advised HERE

Motorcraft plugs are the best choice.
