Spark Plugs?
For those of you running 20+psi what spark plugs are you using?
I'm still running a stock heat range, but that's probably why I'm having to pull so much timing to prevent the knock....
Also what brand and type? Iridum?
Part# would be acceptional too! I'm running NGK Iridum IX, BKR6EIX-11, with E85. I should probably go with a colder plug, but not sure 1 heat range or 2? When it's cold I have a hard enough time starting this thing, and I don't want to have to pull the plugs once a week to clean them becuase of fouling!
