I don't know, I tried Bosche +2 platinums in my Jeep, but it seems that they don't like them. I'm gonna get new copper plugs soon and see if it helps my really rough Idle situation. I hope it does.
I'm guessing that you should use whatever type of plug your vehicle was designed for, (unless you have an aftermarket ignition system) because voltage sent to the plug might create a stronger/weaker spark because of the metals used have different conductions of electricity. The escort used platinum plugs, so I used those, and it worked out great, now I'm gonna switch back to copper on my Jeep and see if that works out great.
Never messed with gaps though. I go with the assumption that whatever the spec is that the manufacture made is what is best for the most reliable, best burn possible without misfire, or weak spark, as well as long plug life. Wide gaps have to be regapped more often.
