E3 Spark plugs

[Iron Ranger]

I haven't used these in my ranger, but I do use these in my Chevy Cobalt. They are not worth the $9.00 per plug price. They tripped engine codes like crazy in the winter time for multiple misfires. Performance was the same, gas mileage dropped slightly(1, maybe, 2 MPG).

I don't know how well these would work in a larger engine, like a 6 or 8 cylinder. Maybe they work better, I don't know. But I do know that these are not meant for 4 bangers.

i think the plugs are ment for older vehicles maybe.

I've got then in my Mother in laws riding mower. They were the only brand my local TSC stocked that fit. :annoyed:

They work.

[prefab08]

got them in my 4.0l SOHC and they made a hude diference then i whent to taylor whires with them and i havent had a single porblem .... even after i whent with my diablo sport tunner the still work great no problems at all:icon_thumby:

[olranger]

sounds like a waist of money to me, use regular plugs like you always have been

[BlackBII]

A spark is a spark....no matter how much you try to change it.

[snoman6115]

no its not, the plugs are very good. my buddy got them in his 94 4.0 and they added 5 mpg, and they werent $9 each more like $5 not too much more than autolite dbl plat

[blackwidow67]

yeah and the double platinum is a waste of money too. unless you have a high power ignition, like an msd or something, to where you are adding more spark to the plug, then anything more than your standard motorcraft, ngk, or autolite is more than sufficiant.

+1... Plugs are plugs, they all do the EXACT same thing... No plug can make a larger, hotter spark than the next...

[nitrofan1]

Ok. Facts time. A plug is a plug. Absolutely true. The difference?

Copper has been the standard for the last 70+ years but the wear rate of copper is high in normal operating conditions.

Platinum is harder than copper so the wear rate is lower. The reason platinum plugs came about is the fun factor (NOT) in putting plugs in late model vehicles.

Iridium came about because it's twice as hard as platinum. It currently has the lowest wear rate available on the market.

Now you CAN run all 3 in any car. But would you want to run a plug that gets around 30,000 miles in something that takes hours to change plugs in? I know many will say I can go 100,000 miles with a copper plug and that's great. But industry results say 50,000 for copper, 100,000 miles for platinum and 100,000+ for iridium. If the gap is steady and the spark stays optimum why not use the best? Now on to those gimmick plugs.

I sell Motorcraft, AC, Autolite, NGK, Denso, E3, Bosch & soon those Plustars. A plug will fire what it gets voltage wise. The heat range is the plugs ability to dissipate heat, not generate it. A hotter spark is the only thing that will increase performance, not the plug. All those forked, split etc... plugs work the same as a standard plug. Read results from independent labs, not the manufacturers catalogs.

If you like copper plugs, platinum or iridium or even E3 it's all about what you are comfortable with.

i first heard about the E3 plugs on horsepower TV. they ran the E3's and a leading competitors platinum plug on an engine dyno a few times and had some pretty compelling results (i usually am not the type to buy into gimmiks and hype).

im running them in my blue escort and i cant say either way fuel economy wise because that car has always had fuel economy readings all over the board anyway. but it seems to run fine just the same...

+1... Wear rate should be the only reason you buy a more expensive plug...

I absolutely LOVE the little demo they had on there with the spark plugs in a "box" showing how the E3 made such a "bigger" spark than the competitor, lol... Funny stuff... What they NEVER will show you is what ONE spark looks like... Yeah, they turn it on and it sparks a bunch, but you are not seeing ONE spark, you are seeing thousands of them... The only way to increase the spark is to increase the amount of current going to the spark plug...

It also has to do with the model of the vehicle. I did some research and found out that the AC Delco factory plugs are iridium off the bat, and that GM and AC have worked hand-in-hand to make this plug work specifically for this car.

There are lots of reports of burned up coil packs in the Cobalts because they used "aftermarket" plugs, little did they, or I, know that the AC's are the best for this car. Lots of computer stuff under this little hood. Switch around one thing, and it throws the whole thing off.

I went back to the Ac Delcos, and what a difference. No more sputtering or idle loopage, and the starts are faster. I won't know about gas mileage for a while.

So, E3's work good on some vehicles, not so good on others.

[feellnfroggy]

I would think that the metals have different resistances that affect the spark creation. Its the excess of spark or lack thereof that the computers pick up on. But if buying an aftermarket spark plug I would def check plug gap, If its true and there is more resistance/less spark from a certain plug then I would give it less gap than standard(not by much) and see if it helps before I knock the product itself. Back to back lab style dyno runs ( and I know we have all seen them) are hard to argue with, unless your just braggin about HP. there are too many controls with a lab style engine dyno.

Go with the recommended gap the Manufacturer's catalog states if you are not going with an OE plug. Course if ya dare a Bosch 2, 3, 4 whatever don't try to gap. lol

Meh, nothing a center punch and a ball-peen hammer couldn't fix:D

[chippy_69]

I put one in my push mower and noted a huge difference, where it used to bog down it powers through now, loads more torque. 8 or so months ago i put them in my 03 4.0 and fouled 2 within 150km, put 4 in my gf saturn and it ran like shit you could feel misses here and there. but the worst was it held the idle so high, if cruising around 2000rpm push in the cluthc and it would jump 2700-3000 hold for 5+sec and then come down to idle. all i have to say is NEVER again in a vehicle. the simple carb. mower loves them tho and i would do that again

hope that helps, but if your anything like me you will read a bunch of reivews and then try for yourself anyway! ;)

[2.3 lowranger]

im running them in my ranger now and i like em they seem to work better in my opinion.

[lil red]

we have em in an 86 mercades 190e(enduro car) i hate em, but i dont know how itd run with oem boshes in it, im bosh for my german stuff, and autolight or champion(jeep dont like autolights) for my american, ngk for my jap stuff

and the yaridium crap, rip off

[yodaman1151]

heard of the pusltars? they are supposed to be a capacitor type plug which doesn't make any sense to me but we used to sell them for $50 A PAIR!!! now they are only $25 a pair but are only supposed to last something like 50,000 miles
