I just realized that I have been using 2 different kinds, but would like to use the best possible spark plug.

The 2 I have used were BUHWX-1 and BUHW-2 both from NGK

If someone knows of a even better plug, let me know, otherwise which of the above 2 should I use?

Thanks

The BUHW-2 was the one that was original from the mfg.
