Does any one Knows the difference between spark plug NGK BR8HS-10 and BR7HS-10? I've asked for a set of spark plugs for my Yamaha 115 BETOL yearZ and I get the BR7HS. When I removed the Spark plug I found BR8HS. Seems to run fine but is there something to worry about?

The 7 is just slightly hotter than the 8. With NGKs, the lower numbers are hotter. With Champions, the higher number is hotter. I'll bet the last servicing dealer didn't stock the 7s.
