Spark plugs, what's your choice?

I've always used NGKs and currently have D9EAs in the 79 and DR8ESs in the 82. Both have different numbers as you see but both owner's manuals refer to them for use in sustained high speed riding. I know the R in DR stands for resistor because my radar detector goes haywire (alerts constantly) w/o them but what about the rest, 8ES instead of the 79's 9EA
Shouldn't they interchange
So, what's in your CBX

Terry, i have used NGK DR8ES-L with no problems.
On my '81 i have NGK Iridium DR8EIX with approx 20,000 miles on them and will be buying them from now on.

Those are $11 each around here as compared to $2.25 each for the standard NKG D9EAs. I can get 2-3 tankfuls of gas for the extra $$. :)
And apparently no one else uses spark plugs

Hi Terrry.
Just checked and I have NGK D8ES L in mine.
Not had a problem with them yet. I use NGK spark plugs every day in cars, at work, and they don't let me down very often.
Cheers

I wonder what the 'L' stands for? Noticed the Canadian models have another letter designation as well?

Had a similar discussion on another board & it was said to be "batch" identification ??

I had it explained to me that it meant a half of a heat range. So a BR8ES-L would really be a 7.5 plug.
