After reading all of their literature and 'news' articles, I see no satisfactory argument to use these pulse plugs. How is 1,000,000 watts superior to 50 watts? On their video, what plug are they comparing to? It's also funny how they designed their own testing method, E-PEP, to support their own position regarding increased torque. According to their own literature... everyone using these plugs will see a 5% increase in engine efficiency. If any product could do that, we'd hear about it constantly via every media outlet and they would charge a lot more than $25 per plug. I'd love to know what the longevity is like for these plugs. There's alot of areas where we could spend $200 on our discos, but not for plugs alone. I think these are the new definition of voodoo plugs, but if you try them tell us about them! I'd love to know before and after MPG, performance, etc...
