I was wondering if anyone knew much about these new E3 spark plugs...
I've heard a few good things about them such as giving you an extra 5 HP.

I've just never been a firm believer in throwing high dollar ignition parts on a stock or mostly stock 5.0.

But I just wanted to see what everyone's opinion was on these...

Also, does anyone know who makes these? Denso, NGK, Champion??

I was watching horsepower tv and they had them up there...heres the video...who knows if this is rigged or not...

Spark plugs for automobiles small engines and sports craft

i saw it on horsepower tv. the tests they did seemed like it worked pretty good but you never know.

i went out and bought one for my 4 wheeler. its expensive, like 7 or 8 bucks, but it has a lifetime warranty.

the only place that knew what e3 was was oreilly's.

Exactly..........

E3's another Split Fire plug......AKA marketing gimmick

E3 is an Advertiser on Horsepower TV so naturally they are going to set the test up to work to their advantage. Just stick with good old reliable Autolites and your 5.0 will be happy!
