Autolite plugs after 50+k miles - read

After a few misfires I finally replaced these with Motorcraft finewires. My '97 F150 startes better, better mileage and runs smoother.

What do you think of how they look? A plugs condition can say alot of how the engine runs. The gap exceeded the max limit by the way.
