Quoted from lancestorm:It's no different than the mid-2000's Ford F150's that are $2000 to change out the spark plugs. Damn difficult and time consuming to get to them. There's a tool around $120 to get them out if you have the knowledge/confidence to do the job yourself.
It is not that hard and the price is closer to $400. Definitely not $2000. I did it on my 2001. It did take me about 3 hours, but I could probably do it in 1.5 after doing it once. That has the spark plugs that potentially blow out of the block, not the ones that break when you try to take them out. There is a lot of stuff in the way, but you can definitely work around most of it. Only specialty tool needed was a 7mm swivel socket but moving the fuel rail wouldn't be too hard. Besides the plug design and potential for disaster when removal the procedure is the same. They replaced a shitty design with a shittier design with the 2 piece spark plugs..
With the 2 piece plugs that break off I recommend a shop doing it and IF a plug does break they have a tool to extract it. Or roll the dice and follow the recommended directions and hope for the best!
Anyway 180,000 on my truck and it runs like it is brand new.
The good news is you only need to do it every 100,000 miles or so.
