Has anybody ever used the E-3 plugs? I was going to order, thru summit, some NGK's (gotta love 'em) but while browsing I ran into the E-3's. Says it can give more power - better fuel economy from the design of the electrode. Shorty plugs too.

I running a set in my truck right now, I orderd them thru Summit. I am running the E3 3.64 they are equivalent to the the Autolite 3923's they have good low end pickup as well as good high end. I havent noticed any mileage gain yet, it make a little while for that. I am also running an MSD ignition. These plugs are gapped at .045". Hope this helps.

How do you know they are equivalent to 3923's ?
Is there a web site with details?
Thanks

Any time you change plugs, unless the old ones have less then 10,000 miles on them your going to notice a slight to good differance in running depending on how bad the old plugs were > Spending money for pricey plugs is a total waist > All a plug can do is ignite the gas > other then heat range changes for mod reasons the only performance change available to a plug is the gap and unless your a granny driver always open the gap 10 thousands > Best way is to open the gap 5 thousands and run it for a while couple a tanks a gas anyway > Then open an additional 5 and retest > Keep doing this till you hit the point where opening the plug that last time caused what ever > Worse milage> Engine stumble > Lose of power > Anything noticable > Then back it of 5 thousands and WALLY > This is your perfect gap for your paticular ingine and mods > one point here > any additional mod changes after doing this requirs you to try a retest but only starting from your present setting > goes a lot faster > one sujestion that really is one of the smartest things you can do > change your coil to one that puts out around 28 or 30 thousand volts but no higher > It must be oil filled and it must say verible spark or comtroled spark or something that means the same thing > this is the best coil mod possible for the very best performace unless your running your engine wide open like in a dragster >Try to get a metal case coil > Composite incased coils are ok but run way hotter inside because the composit does not disapate the heat near as well as a metal one > Second plus is any metal cased unit will out live a composite

I have been trying different spark plugs in my truck. I will keep the others, I only run them a few hunfred miles. I can use them in my wife's car so yes there is a method to my mad-ness. If you read all the technical information at the E3 web site you can learn allot about sparkplug and combustion theory. One of the things I learned while reading their information is that the best set up for quick comubustion is an edge to edge surface for spark plug firing. One sparkplug trick racers use is sidegapping. When doing this, you can get better mileage and power. With the E3 plugs the present 4 contact areas to center electode there by increase the contact surface area for better spark plug perfomance and much less degradation over time. According to tests run by E3 their plugs should no performance loss over 20,000,000 combustion cycles. A standard plug looses up to 10 percent of it performance at 16,000,000 combustion cycles. The E3 produced the fastest flame front of any spark plug on the market today. Many of the E3 testing procedures are so unique and valid that the EPA has written many of the E3 testing procedures int their tests. The spark plugs through Summit are 5.99 a piece, you will pay that much or more for the Bosch Platinum +4. Get a set of E3's and try them out guarranted for 5 years or 100,000 miles. IF your are interested inordering a set order fro Summit, JEGS was much higher with their prices.

Ever wonder how these specialty plugs can afford all this heavy duty advertising to sell these things > it's called 5.99 a plug here > you can run a regular plug 100,000 miles to and even put the same garentee on them > the thing if is the plug still fires it's good and no refunds given > If you truely feel good about spending this kind of money for a plug that can not do no more then produce a spark just like all the rest go for it > by the way > I prefer champion and they have the softest metal of all plugs and live a shorter life but of all the steal plugs auto lite has the hardest metal and longest life > My opinion tested and approved by me over a period of 50 years of driving

Like every other snake oil company that pops up with each oil crisis it too will disappear. Everyone knows that it is the oil company owned black helicopters that come and wisk them away so that you can't get better gas mileage.

I use NGK's. Great spark plug. I am picky when it comes to spark plugs. It can tell you alot about how a motor is running. I have used the autolights and after 5000 miles all 8 gaps were significantly worn from 3 to 5 thousanths.
I have a MSD-6AL which, as you know, does the 3 spark thing. It seems the NGK's hold up alot better - at least in my motor - only 1 thousands difference in 5000 miles.

I`m using E3 w/ the OE heat and a little hotter than the 3923 it replaced.
If i had to buy it again, i`d buy 1 step colder, simular to the 3923 heat.
This plugs are owesome.
They really help to burn the mix in the combustion chamber so much more efficiently, that the mil light w/ p131,137,151 and 157 comes and goes from time to time.
Part of it is the mods i got. FIPK, ported 68 TB, HO intake and cams, Gibson headers and single 3in cat back 180* Tstat, no clutch fan, jet2 etc.
My point is this. W/ these mods, the engine is runing on the verge of been lean, and w/ the extra spark, now it is even closer to that.
To solve this problem, i`m thinking of installing some FMS injectors(4 holes).
Should i stay w/ the 19lb or go to 21?
What do i need to adapt the FMS propperly?
My truck is 2000 CC 4.7 2wd w/3.92 lsd 5 manual.
Thanks.
There is no substitute for manual, rear drive w/ lsd and power.

How do you get an engine to run lean without modifying or disabling the O2 sensors or reprogramming the PCM? I had no idea that we had that much control over the mixture.

N56629, you are one of the autorities for me and i don`t have the knowhow to argue w/ you, but, you can make a engine burn lean simply by geting more air in and out to the point where the pcm can`t compensate w/ more gas.
This is not my case, but that is the idea.
I haven`t had cods 131 137 151 and 157 before the E3 plugs and i replaced all 4 O2 sensors last year.
What i was trying to say is that the extra spark is burning more efficiently to the point that the o2 sensor may be geting confused by not finding as much exaust gases as it would w/ a traditional design plugs (spark pattern).
Now, will the FMS injectors be a good up grade?
If so, 19 or 21lb? Thanks again.

Sorry, I just don't believe any sparkplug can be the cause of a lean condition. Even if you acheive 100% efficiency in the burn the airfuel mixture entering the combustion chamber doesn't change. The PCM shouldn't have any problem changing the pulse width of the injectors to get it as rich as you would ever want it to be. As for the injectors, the FMS 19# is always a good idea.

I think they rate stock injectors at 19 but some people say they test somewhat less.

I believe that the engine can run rich with a certain amount of mods geared torwards air. You all have to keep in mind that a PCM can only widen the pulse width so much, allowing so much fuel in before it will start to overlap cycles. Whats the sense in letting fuel into the ports when the valves are closed?
If it ain't broke, fix it til it is.

Daddio, you are right they did change injectors in 2000. They may indeed be 21#, I don't know. Unfortuanately they are not readily interchangable. I guess I would still caution anyone that is thinking of going from 19# stock DC injectors to 21# FMS injectors. While two injectors may have the same rating it doesn't mean that they flow the same.

the 21# injectors i have are red with the oval connectors. i can't see a reason for going to a larger injector unless it's in a full out racing application. you may be surprised what the stock injectors will flow.
