Now, if you went to something like an Autolite Racing AR92 plug, then you would have issues because that is 4 steps colder and should only be used on a forced induction application with appropriate tuning.
The Autolite 103s are fine for normal use on the Duratec 2.0. Gap them to 0.055 (some have gone to 0.060 with no issue) and you'll never have a problem. You'll see better MPG and smoother engine operation.
It is important to note that if you're looking for more power, you'll need to get the Autolite Racing AR103 plugs. The flame front is open compared to the design of the A103. The same benefits apply, with the addition of a couple extra horsepower.
Also note that copper plugs require replacing every 10-15k miles. I replace mine every year, it's just easier. Inexpensive and only takes about 20 minutes.

I always used to be of the mindset that a spark plug was a spark plug was a spark plug. Until I ended up with a set of NGK in my Jeep. I was seriously considering paying to have the differentials regeared because it had lost so much power. I never put it down to the spark plugs, until I changed them and it suddenly had use of all 4 gears. Was amazed.

I just put in the A103s gapped at ~.055. I had Bosch platinum's before with 17k miles on them, so not much.
Startup was the same, but for sure this FEELS MUCH SMOOTHER, even with my worn out motor mounts. Idle and while on the move are better. Even if Im not getting more power the smoothness alone is good enough reason to keep using these. Might try 104s eventually see if its the same.
My car DOES NOT like the Bosch plugs. I have a 08 California model SE with 130k miles on it.
But this bring up a question I saw before but not answered, Why is this heat range not installed from the factory?
Also will NGK 103s be pretty much the same?
Thanks so much for this info!
