E 3 Spark plugs

[labill]

Does anyone have any experience with the E 3 spark plug? I went to their website and they show plugs for the Venture.

I've used them and they worked fine. I really couldn't tell any difference. They will probably last longer but I'm reluctant to leave a plug in that long anyway because I'm afraid it won't come out. I guess with some anti-seize it would be fine.

I put plugs into an old GS last far and far it and this spring it wasn't lighting 3 cylinders bc spark was messed somehow by the anti seize which was just on the threads. With plugs out laying on the case the arc traveled from the plug body to the engine case but not from the center electrode to the plug body. Weirdest thing. I used to use a smear of oil on plug threads and thought the anti seize better but no. I cleaned plugs and she ran nice.

When applying anti-seize to plugs, only put a light coat on the tapered shoulder seat of the plug, NOT the threads. It melts and runs down into the cylinder, fouling the plug, even the high temp stuff.

 

I learned this after applying a liberal brushing to the plugs in an old GMC 350ci V8.

Well my experience aint been very good with similar design. I tried a similar plug many years ago "split fire" same type idea a "dual fire" electrode. I had the split fires in a 300 six f 150. When they worked new MPG actually improved by 2-3 mpg highway. But about 10k in truck misfired and started to run like crap. I actually put the old plugs in and it ran better. So a new set of motorcraft plugs went in. Jump forward to about 2005 or so. I was racing a legends car. Engine for them is a Yamaha FJ 1200. I for grins contacted E 3 as they were sort of new and I had not seen them before. The hooked me up with a sponsorship, no money but free plugs for race car, and personal vehicles. About 2 weeks of racing, I started developing a miss under load that got worse and worse. Changed coils, wires, checked grounds fuel all that. Cant be the plugs rite, cause they are new. Well they cooked the ECU. I kept their sticker on the car for the rest of they year, but NGK's went back in after $300+ worth of ignition got replaced.

 

Your results may vary. But for me anything other than like the Bosch or NGK split design has resulted in bag ju ju

 

PS 15 years of being associated with NASCAR and engine tuners/builders NONE of them I had inspected ran those plugs. I'm pretty sure if there was something to them those guys would run them.

I tried them 10 years ago after a friend with a hot Road Star boasted about them.

I saw nothing beyond stock. Seems I remember changing them out sooner than stock.

I had another set but gave them away to someone who thought free was good.

Got my answer. I stopped at Auto Zone the other day and asked about them. One of the clerks said he tried them in his bike and did not see anything better so he went back to NGK.

 

Thanks everyone.

All those are, are sucker buys. They claim to increase horsepower. I watched a dyno test once, and on a 400 inch small block Chevy, they made 4 horsepower difference on a 400 horsepower motor than stock plugs. Plain ole stock NGK last the longest and perform the best. IMHO.
