Im running a BR8EG in my 91yz 250. I picked up some plugs today and noticed that they gave me a BR8ES. Whoops!!!Whats the difference between them? Is the BR8ES a hotter plug? Can I run that plug with out tweeking my piston and rings?
Thanks

The 2 plugs are the same heat range and are interchangeable. Dimensionally they are the same...so it's safe to use.

The G means that the plug has a "Fine Wire Nickel Alloy Center Electrode" and the S is "Standard 2.5 mm Center Electrode". They do interchange without problems.

the "G" and "S" plugs are identical, if they are out of G's, i'll run S's and vice-versa.
