I lost info on the difference between NGK BR9ES and BR8ES spark plugs. I
'think" I have used both at one time or another with LSE EI, but am now
seeking specs on the difference...help anyone?

OK I found the data...the "9" are a higher temperature plug...the NKG's
are rated 2 for coolest and 11 for the hottest. Seems snow mobilers and
boaters know a lot about plugs.

The higher the number the colder the plug. If the plugs get carbon built up on them they are too cold, if they're too hot they show signs of erosion.

NGK's go colder at the number goes up, opposite of Champions. If you take a look at the BR8ES plugs vs. the BR9ES plugs, the BR9ES have a shorter electrode, hence they're colder. I've use either in the RV with no problems.

When I pulled my BR8ES's the other day for compression check, they had a toasty light brown to white color that looked to me like they were running a bit hot. No carbon anywhere. Running a pair of P-Mags on O-320-E2D with 160 hp pistons and burning hi-test mogas at 40-50F LOP when I can.
I think I'll replace with BR9ES next time. Gaps were good at about 100 hrs with no sign of erosion that I could see.

Right, Bob - I did some more reading, and the confusion is the non-standard numbering system makers use to show the heat range...as you said, some get hotter with higher numbers, some get colder with increasing numbers. I think I will put hotter plugs on the bottom, and next 'colder' on the top of each cylinder (using dual LSE ignition.) I see more dark stuff on the insulators of the plugs from the bottom and suspect a hotter plug might be best there.
