e3 Spark Plugs/Reviews

I'm not an expert with spark plugs, but I know that the better the spark is of the plug the better it could be for power and MPG, etc. So I'm trying to do a little research on good brands to use for my Tacoma V6 engine.
From some of the reviews I have read it seems like it is 50/50 on like or dislike for these e3 plugs. Some say they work really well, some say they can't notice a difference. Some even said they had worse MPG's. Some said they worked really well in their naturally aspirated motors, but not so well with their fuel injected engines.

I know that you really need to have these plugs tested on a dyno and in a controlled environment for accurate results. There is a video that I saw that shows the guys from horsepower tv doing a dyno test. Their dyno test shows an increase of five horsepower on a naturally aspirated engine using these plugs vs their leading spark plug competitor.
So I'm wondering if anyone has used these e3 plugs on our new Tacoma engines on a dyno or what they think of them. Have they noticed better MPG's or a little more horsepower, or what? I also see a lot of guys say they use NGK plugs on here so that is also a plug I would consider using.

So tell me what you guys think of these e3 plugs or what other plugs they use and think is the best for our engines. Thanks guys.

 

Thanks chris4x4, that's good to know about the OEM plugs. Does anyone else have any other opinions on the e3 plug or other plugs?

 

For the most part, multiple ground electrode spark plugs are pretty much snake oil. Basic electrical theory will tell you that voltage will take the "path of least resistance". This means that the spark coming off the center electrode will only spark off of one ground electrode and not multiple at the same time.

Only advantage of multiple ground electrode spark plugs is if you have a issue of carbon fouling and this will buy you "some" time before the plug totally fouls. If this is a issue that drives you to multiple ground electrode plugs in the first place, you got worse issues anyways.

Splitfire just recently in 2007, settled a lawsuit brought by the Federal Trade Commission and removed most of their claims of increased HP and MPG by using their plugs.

Vast majority of people that claim increase MPG and horsepower of installing multiple ground electrode plugs are just really feeling the effect fresh plugs give them. So it is mainly a "placebo" effect more than anything.

For 99.99% of us, using the factory spec'd plug will suffice and give the best overall outcome.

 

No Dyno results with the E3 plugs, but i just recently put them in my truck and noticed and increase in power (bottom and top end) havent really been able to test the MPG ill get back with the results of that.

 

I replaced the factory ngk's at about 80,000 just thought it would be a good idea since it is 9 years old and still had factory plugs. I replaced them with the ngk ix iridium plugs. Didnt notice any hp gain, but picked up about 1-2 mpg's.
ngk pt# 6341

 

Im no crazy god at tacomas like you are but i tried Platnium 4's (brand new) and noticed a difference from the NGKs that i had in there. And that same day heard about the E3's and tried them with noticeable power increase. Could of been something else that effected the power gain but i must say i was impressed and so were my friends that also have Tacomas.

 

Yeah the Platnium 4s replaced the old plug and the E3's felt like i got more power compared to the Platnium 4s. unless your saying the OEMs were just old and it wasn't a fair test.

 

Hmmm, maybe thats what made the E3's seem so much better. I have the 3.4 you think that might make a difference?

 

Alright guess ill get those next then, thanks chris.

 

I put the E3 plugs through the ringer and they didn't hold up. Granted it was in a V8 Mopar on methanol, but the porcelain broke. Prior I used both NGK and ND plugs without an issue.
I say stick with the Denso plugs.

 

I'm reviving this thread since I too saw the show with the dyno testing the E3 plugs. It's actually on powerblocktv.com and it's the second time I saw it. They dyno tested the E3 plugs with the competitors in an LS1 motors and they showed that the E3's provided lower emissions and an improvement in mpg over the other plugs and this was a new plug to new plug comparison.

I'm a little bit curious about these plugs now and more inclined to try it. I have less than 7K miles on the truck now so my plugs are still pretty new and I have been tracking my mpg on each tank and get about 16.5 all city and 18-19 all highway and 17-17.5 mixed. I'd like to see if the E3's get better mpgs and there's only one way to find out....

 

I can't remember exactly what show it was, but I do believe it was on Spike TV. The show I mentioned above says it is from horsepower TV but I really can't remember.
But I think I remember them doing this test on a naturally aspirated engine, and not a fuel injected engine. But e3 does sponsor these shows on this TV channel, so I'm not surprised if they did these dyno testings on different shows on the same channel and different engines.

So keep in mind that the testing could be a little biased.

 

On a side note, I love how bako's sig says buy american and we are in a Toyota forum lol
