E3 Spark Plugs, anyone?

[deadbird]

I'm running E3 spark plugs in my 08 sport cobalt. No problems and if anything it even smoothed out my idle slightly. Maybe a very minor increase in power but that's about it. Nice not having to gauge the bastards too.

Im running Bosch Plat 2's, they seem to running fine. i guess it all depends on preference. i love bosch parts. so i tend to run bosch in most everything i drive. how much more fuel efficient could ya get with a different spark plug? (just throwin it out there)

Multi-prong plugs don't work well in boosted applications. Just run AC Delco or NGK copper plugs. Replace every 10,000 miles. They're cheap, and work extremely well.
