Hey all.
I heard from a BMW tech that you do not have to run as low as gap in the plug as you might have too in lower elevation. While I was in California I was running a .028 gap it ran and idled fine. Here in Colorado (5280 Ft) it seems to have a rough idle, kind of lumpy. If the tech is right then I should be ok with running a little wider gap with the same boost levels. I was just curious if any one else has heard of this.
