The 2 black ones had bigger gap, can this be it?

Yes the gap can and will affect that. What was the gap set at on the two different plugs, and why would you run a different gap?

The gap on the black ones was .30 and the others was .25, but i dont know why, since i set the gaps the same way, guess i made some kind of mistake...
