    1200 Plugs

    I noticed that my engine had BR9ES plugs in it when I got it. I run BR8ES in my 760. Aren't the 9's one heat range higher? What should I be running?

    this is out of NGKS SITE... NOTE THE LAST LINE..The heat range numbers used by spark plug manufacturers are not universal, by that we mean, a 10 heat range in Champion is not the same as a 10 heat range in NGK nor the same in Autolite. Some manufacturers numbering systems are opposite the other, for domestic manufacturers (Champion, Autolite, Splitfire), the higher the number, the hotter the plug. For Japanese manufacturers (NGK, Denso), the higher the number, the colder the plug.

    BR8HS for stock head.
    BR9ES for pro tec etc head.

    What head did you have higher comp needs a 9 stock head has short plug aftermarket would have long plug.

    So I guess it had the right plugs in it. It had the Greater Yamaha head on it, remember it was like your Cool Head Scott...

    Thanks Scott. Should I also be running the same plugs in my 760, it also has a Riva head, pipe, F/A's etc... I currently run BR8ES plugs in it?

    Pistonwash was a big fan of BR7HS in place of the 8s.(stock cyl. head)

    I like the iriduim; BR8HIX.
