My racecar is due for some new plugs and picked up a set of the new E3's at Jegs today. They cost about twice as much as the Autolite's but if I can stick them in without indexing it would be worth it.

On horsepower they showed to make 5 more hp on a smallblock chevy plus they burned much cleaner.



Those results are from where? I believe they are just another marketing ploy like splitfire plugs were. The spark is still going to take the path of least resistance....so I doubt they have any advantage over any other plug...but that doesn't mean they are bad, just probably no better than any other plug.

just my opinion....
