Ford Triton Engine Spark Plugs PSA
While Ford is well known for spitting spark plugs, the ones that don't are the ones that tend to break on removal.
04-08 I believe, the super long 2 piece sparkplugs were used in the 3V heads (maybe others).
Having just bought a Mustang GT that is a sticker, not a spitter, I decided to change plugs now with low miles (35kmiles) than procrastinate.
Got all of them out no problem, no oil needed, but even at such low miles on a car that is basically in new condition, every plug was very corroded in the hole and required working back and forth a bit and they all squealed the whole way out.
If you have one of these, the plugs rusting (no carbon on mine, just rust) in is a real concern. Assuming a linear rate of corrosion or carbon vs hours/miles, and how hard these were to remove, I'd estimate by 100k miles, you have a 100% chance of breaking some unless you spend the time and work and lube them, which takes days, not hours.
