I was looking through a car magazine( I think it was car craft) and there was a write up about these plugs and they said these would provide a 6% increase in horsepower, the web site is www.E3sparkplugs.com I dont see how this is possible to gain much horsepower from plugs,has anybody tried these things?

i havent tried them in my car but i have tried one of those E3 spark plugs in my snow blower and it wouldnt even start. i put the old plug pack in and it fired right up.

I think they recieved their results after repeatedly inserting the plug into the G-Box in a thrusting manner.

6% horsepower, per plug, correct?
So we'd gain 36% Horsepower?
I'm going to go buy some of those right now.
I wonder if I can put two of them on each cylinder... So... 72% Horsepower gain?

Combine that with my G-box and my Ebay Speed Chips, and I'm ready to run 12s.

Spark plugs don't give you horsepower. You might regain lost horsepower by replacing a fouled set of plugs, but you won't gain anything. The end.
