Bill,


My take on the spark plug heat range is that one would want the coldest = plug available as long as it doesn't foul resulting in misfire.  I saw= no evidence of fouling in either location so I don't think the BR10EIX are= too cold.

Steve,

 

The factory plugs for the Renesis lea= ding application are 21 mm and the trailing are 19 mm.  The BR10EIX ar= e 19 mm, wouldn’t this make them even colder in the leading location?  Should the leading be hotter than the trail= ing???  Does it matter??

Try this:

 

Gap the plugs down to .010". I= used a MSD-6A on both leading and trailing. No misses up to 9,600 RPM.

about the 10 heat range but I am in= Florida and all of my data in Hebron Ohio. The NGK 11.5 plugs are $25= .00 each and are retracted tip side electrode. Can be gapped and are ice cold. A 12.7 mixture should get you 1575 to 1600= EGTs.
