I found this Pulstar spark plugs very interesting . They are claiming 5-7 % power increase by using a different spark technology.

Here are some Videos

I also found some videos with Dino tests confirms the increase at the performance but there is also a controversy on these plugs that some say they damaged their cars.It is overheated , melted etc.

Is there anyone have used these plugs?

Thanks
