As described
Does what it says on the tin. I use these on a ZX14, ZX9R, and on a SV1000S. On the 14, I go one step colder (CR10EK) for nitrous use. The SV has these or one step hotter (CR8EK--which is what's spec'd for that motor), depending on which I had handy at the time. As per the ancient motoman site, these are good for 2hp on an inline 4, vs 'normal' plugs. Works for me. I have not pushed more than a 50 shot of nitrous past them, but don't forsee issues with the plugs so long as the ignition timing is kept in check.
