From my understanding the plugs start to lose efficiency even without the fuel concentrate at around the 18-20k mark anyway.

The Torco stuff is pretty good...

Yes that is what many say but it comes down to how often you use it. Mine were orange and I indeed get a misfire and changed them out and it was fine. I now use actual torco race fuel mixed with gas so its not an issue but I have no certain answer on whether or not the torco conenctrate causes decrease in plug function as long as there is no misfire.

Wonder if someone can explain why a fresh set of plugs can make such a difference?
