I don't know what year your car is , but if you have the two piece plugs , I think they changed sometime in 08 , the longer you wait the harder they are to get out without breaking ...

the dealership will charge you up the wazoo to change them and most likely they will break more than one and then charge you up the wazoo even more. Take a day, take your time, follow the procedure and you should be fine.
On another note I wonder if using something like seafoam before hand would help clean up some of the carbon deposits on the plugs??

On a side note just yesterday I had a customer that said his local dealer in the SF Bay Area wanted $750.00 to do the plugs on his 05!
They were convinced they would be breaking plugs.

Well mine's got 7 years and almost 70k miles on it - are the odds in my favor if I take my time and do the method you mentioned KC?
When I replaced my factory midpipe this winter I snapped off an exhaust manifold bolt and had to find a mechanic with a welder who I could tow the car to and bail me out of trouble. So I'm wary of taking on jobs I can't just knock out easily

Free AAA tow is cheaper than a noise ticket or CO poisoning. And I couldn't find a conclusive answer on forums, but it seemed more likely to burn a valve with the short stock manifolds than just running open headers.

What spark plug do folks recommend to avoid issues in the future? Autolite HT1 or Champion Double Platinum?

Once the plugs are antiseized they don't get the carbon build up. You can use a 2 piece plug without an issue. I just pulled the plugs on my F150 (same issue) for the second time. Plugs had around 90,000 on them with antiseize, came out no problem with no carbon build up.

I changed mine at 50,000 miles. Took my time and followed the TSB. I soaked them, turned a little then soaked them some more. you can do it, just take your time. I didn't break any of them.

My Sc'ed 07 Mustang has 30,000 mile on it and I'm about to change Spark Plugs for the 6th time. I always change them once a year with Autolite HT0. I've never had a problem but I do use the anti-seize on the barrel. I have 5 used sets sitting on my garage shelve with appx 5,000 miles on each set.

Going under the knife... that initial 1/8th turn is nerve wracking
and yes I know it looks disgusting in there. This car has seen several rough New England winters as a DD

They are worn out IMO and I put in new ones and antisieze them. The only reason Ford says there 100,000 plugs is so you don't mess with them until you are out of warrenty. When I notice a small hesiation or drop in rpm and mpg I change them.
