There is a difference in removing the top half of the intake manifold to replace the passenger side spark plugs and pulling the lower intake and removing carbon off the back of the intake valves due to rough engine running. This problem can happens in the upper 100,000 mile or above area of operation on average if you drive above 15,000 miles a year and do not do a lot of cold weather warmups.

OP, what is your mileage? The carbon clean might beneficial if you have a lot of miles. I would do the plugs first and see how they look and how it runs after.
I literally just did all my plugs yesterday in about 40 minutes. That included 1 beer break also.
I would do everything you can yourself to save the $$ and let them do the things you cannot.
If you pull the labor cost of the plug exchange out along with the dealer plug cost the carbon clean job may be economical and worth it for the dealer to do.
Good luck

You will also have more build up on the valves if you suffer from the stutter often due to oil/water crap ingestion from the Cac. That is one of the helps the tiny hole will do for you.

Well...considering it's been 15 degrees lately...I was only weighing my options whether or not if I wanted to do it myself. It looked pretty self explanatory to me by looking at it...just wanted to see what the dealership (stealership) would charge. But...in reference to your "ignorant" comment....think before you mouth off.

No reason to call them a stealership, to me that's ignorant. They are trained to do their job hence the difference in what they charge and what someone who has no knowledge can accomplish. If you have the tools and knowledge, my comment shouldn't bother you one bit. If I can save myself $300 and it only takes less than an hour to do it, I will. If you aren't having a mis-fire, then surely you can wait until it warms up a little to change your own plugs. Sorry to offend you.

There is no reason to remove the intake on a 3.5 Ecoboost F150 for a plug change. I did my 2011 in 40 minutes during the winter in a parking lot.
On a 2011 3.5 NA Explorer, yes the upper intake plenum needs to be removed. Going slowly w/o previous experience, it took me 3 hours. The only parts required was the plenum gasket ($14 from Ford) and 6 plugs ($7 each). The dealership wanted $350 to do the job. I needed this done right away, so I did it.
Looking at the valves in the Explorer, there were no deposits on them at 93k miles.
