Does anyone know what I should gap NGK laser iridium plugs at? I just got the performance distributors coil on plug kit and a Brenspeed tune. I gapped the plugs at .062 and I can tell a difference until about 7,000 RPM and I think I'm getting blow out. Any help would be appreciated.

 

.062 is a bit wide. On an NA setup I would run closer to .045 and on an SC setup I like .032.

These are the plugs I run. NGK (6510) LTR7IX-11 Iridium IX Spark Plug on my forced induction setup and I have zero issues.
