Spark Plugs

I've experimented with splitfire plugs in the past. They ran so clean you could not read them at the track. I've seen plenty of tv show claims about the e3,including some test time at MIT. The plug just flat out works. I' did see another show where the typical chev 350 was run on a dyno with and without the e3. It made about 7 more h.p,but the really big thing was much lower emmisions and a lower fuel consumption. I have not tried the e3 myself yet. Was thinking smalller scale,maybe a new e3 plug for the snowblower next season. Those small engines always run rich,so a good plug would really help it.
