Out of curiosity. I thought I read that the factory plugs gap is 0.028" - 0.032".
The plugs (NGK zfr6f-11) I bought for the engine are gapped to .44. Which is correct?
That's exactly what I ment I was told to do mine at .044 and the car ran like crap and thought to my self too check my camaro that is strictly a drag car that has a full msd setup and I only run .035 so I brought mine down to .030 on my mazda and runs perfect
