Spark plug replacement 4.6 engine
Truck is an '07 with 80,000 miles & with the 4.6 engine. I've owned the truck for a year & want to replace the plugs. Dealer wants $300 bucks to do it, plus tax. Does this engine have the issue with the plugs breaking off? I'm fairly good with a wrench, but should I just let the pros do it & couph up the $300? Any special tips, tricks to accomplish this without any major headaches? Thanx a bunch!

Thanx for the replies & the link to the write up. I see that the OEM plugs are like $.3.50 at Advance Auto. The quote from the dealer included replacing the boots which are like $6 bucks a piece. So he wants about $240 for labor. Nah, I'll do it myself. Should I soak the plugs in PB before I pull them & does it matter if the engine is cold or warm? Just want to avoid any headaces.

Room temperature, no PB blaster required.
Just ensure you blow out the plug wells with air to eject all the spooge
Good luck!

Make sure the plugs are genuine Motorcraft, not OEM "replacement" Autolites.......
Motorcraft SP493's are $2.49 each at rockauto.com, and Motorcraft WR6128 COP boots are $5.79.
The dealer is charging you full retail for the plugs and boots, which probably puts the parts bill up around the $150 range. With that, $300 isn't that bad.
