I have mixed emotions about these plugs that effectivly make the burn happen faster. Basicially its like bumping the timing without actually bumping it. If your car is factory tuned the timing might be so safe you can get a small benefit from it but for instances where your car is tuned I dont see any point in them. If you car is tuned for normal plugs I wouldnt want to put these in because they could make the burn happen too fast.
I wouldnt suggest using these plugs in your car and then go get it tuned either because they are just going to have to set the timing lower by a little because of the faster burn. Then if you decide tostart using a different plug you will be at a disadvantage.
I say if your motor and tune is stock these might be ok.
only argument i could make to you, is that, especially at high rpm, the burn period is so fast that as long as there is no pre-ignition, it would burn better. Faster yes, but i think the point is that they burn everything more completely than other plugs, utilizing all the possible fuels.
Whats the concpet behind these? Same as those Pulse Plugs?
They appear to be more like the Splitfire - which I've heard sometimes had an improvement, sometimes made things much worse, and often just did nothing. Anyone have any dyno tests or other hard numbers about the E3s?

E3 spark plugs
I use them in my lawn mower. It actually was a pretty big difference.
