Cool link Joe! I found this in a TSB from NGK from a few years ago:

“If your vehicle was not calibrated for a fuel blended with ethanol the following  
adjustments can be done to restore the expected mileage and performance prior  
to the change in the fuel type. NGK Spark Plugs Canada Limited recommends to  
install a spark plug one heat rating cooler than OE to dissipate the increase in  
cylinder temperature as well as adjusting the spark plug gap setting to 0.010”  
smaller then the vehicle’s factory setting (Note: do not reduce gap to less than  
0.035”).”

Im still using the BKR6E-11’s (still at .044 factory gap) that I used before E85 without issue, but I do have a pretty mild setup compared to most of you guys. Im also using an MSD 6A box with a Blaster coil. Maybe Ill experiment with a step colder on the next set but in a year I havent seen any indications that I _need_ to make the change.

Was thinking about this today when I almost ran outta gas for the weedeater and found a few gallons of leftover E85 in the garage, haha. Whats the application?
