I was searching around for spark plugs. Last year I used AR 134's in my motor, they lasted two races until they began to misfire. Changed them out to Denso plugs and ran rest of the season with no problems. I switched back to the 134's this season just to see if I got a bad batch. I ran the practice session (5 laps) last week with no issues. Went to hot lap this past weekend and it misfired at 5800 RPM. Changed the plugs for heat race and had 0 issues out of the 134's.

I'm getting ready to switch over to the NGK's and throwing out the 134's. I spoke with Vic Hill about them at the track and he said they used to be a really good plug but he has started having lots of trouble out of them.
