			Which spark plugs NGK BR7HS or BR7HS-10? I believe it is the same plug only the -10 is gapped differently. Anybody know which I should get? Pretty sure my motor has BR7HS in it now but I'm at work. Worst case I can look when I get home tomorrow but wouldn't mind picking these up on my way home.

			I believe the -10 means a resistor plug to prevent electrical interference with VHF radios and LORAN-C(when we still used LORAN C).

			Thanks for the response Ferm.   I got home and looked under the cowl at the sticker and it says BR7HS 10 so that is what I will go with.  I saw some stuff online about the resistor plugs so you are probably right on all accounts........

			Picked up 6 plugs and 3 gallons of Penzoil XLF synthetic blend 2 smoke lube juice.   Walked out just shy of 80 bucks lighter than when I went in.
