gimmick. any new plug is likely to run better than a worn plug. platinum is a poor conductor which slows down material transfer (wear). i've had best results with Autolite iron plugs or NGK copper. all high dollar plugs do is lighten your wallet.

I do not know if the youtube video and/or the dyno graphs are entirely reliable but take this as additional information only. I purchased these plugs from amazon.com for a great price but notice no better or worse change. Just likely to keep them in longer.

Plain copper plugs perform better than platinum, they just wear quicker. I was curious about the E3 plugs also, ended up going with E3 tires instead, better investment.

Unhappy E3 plugs :(

Tried E3 plugs in a 79 shovel. Second ride after, bike was not rideable. Thought S-S carb was the problem. Tore carb apart and all looked good.Put old plug's back in and ran perfect again. I do not reccomend.
