Hi Tracy

 

My engine came with B9EGV plugs. The race rally people  recommend them. 180Hrs is not bad on unleaded. How long do BUR-7/9 EQ plugs last? The photo of my plugs does not show the color accurately, they were all light brown. I have never seen a BUR plug, what do they look like?

 I’ve installed the B9EGV in my 20B based on Paul Yaw’s recommendation.  He found they made the most power on his dyno runs.  I recall at the time he also warned that they may not run much beyond 50 hrs.
