I've been searching around and got a lot of answers to the same question ![facepalm](https://www.miataturbo.net/images/smilies/facepalm.gif)
I just bought a set of NGK Power coppers. What should they gap?
So far i've seen people saying .045", .040", .039", .035", .030" and .020". Which one is it? I'm running stock ignition system so i assume the 45 is too much since thats more for COPs.

.025 was the most I could run on the stock coil. I run .050 with the Toyota cops. The seemed to blow-out in colder temps, so you may want to take .005 out if its warm out (but you're in Chi-Town so its probably cold).

What do you guys think? The lower right is number 3... 2nd to the back of the engine
it had some oil on the rim (the washer/gasket) but i dont know if its from when i did the compression test or whatever.
There was no oil on the tip or the threads of the spark plug.
