changeing spark plugs

I have a 2007 fx4 with a 5.4 . I am going to change the spark plugs out so I was wondering is there any tricks that I could do. I know if your not careful they will break and then you have to get an extractor. any suggestions?

I have had mixed results with all procedures on the crap design plugs . My best for the crap design plugs... Warm engine up . Pull coils . Put Seafoam Deepcreep penatrant in each plug hole . Let sit over night . Best of luck ! Broken ones are not hard to remove with the Lisle tool though . So I do not worry too much . Maybe someone else has other thoughts though ....

With a cool engine, use a small amount of PB Blaster to soak the plugs (the stuff works where others fail) and then wait half an hour. Work very slowly. Get the Lisle tool first as even if you are careful, you may still break one or two. I broke two of the eight. If you have it and don't need it, great, but if you don't have it and need it, you're up a creek without a paddle.
The back two on the passenger side will be much easier if you remove the computer harness.
Also, shop around; the plugs range from $11.99 to $21.99 each depending on where you buy them.
As for paying someone to do it, Google search and you will see horror stories of what it cost after plugs broke. Don't know if they're accurate but it convinced me to do it myself. My problem was that after reading about the plug issue I waited until after i got the flashing check engine light to do the plugs. Ended up with a blow catalytic converter.
My 100,000 mile plugs actually lasted 100,105 miles when i started getting misfires. So if you're far below that you may have a while.
