I was just watching Horsepower TV on Spike TV this morning and they did a dyno test on spark plugs and with no other engine changes other than spark plugs run at the same engine temperatures, the E3 spark plugs produced 5 more horsepower than the other performance plugs..

Plus they burned less fuel..

Anyone running these plugs?

 

I saw that episode also and was curious myself. I read conflicting reviews on the net with regards to longevity, reliability, etc. There are also Torque Master's available via Carson Toyota. Looking forward to specific feedback.
