i dont no if anyone here has used them but i got a set of E3 diamond fire plugs an they are junk, my car misses like crazy with them i might of just got a bad set i dont no but i wont buy another set.

they suck. i wouldnt use them in my lawnmower
Too fancy for a plug. Just stick to NGK's :)
yeah ngk probably be the best
I could have told you this long before you installed them...
Try a set of the plain old autolite 103s, been running them for the last 50,000 miles in the goat with no problems at all, I change them about every 20,000-25,000 miles and they still look new
Another vote for Autolites. Great plug, I run them in everything anymore. They do as advertised.
Don't care for NGK's.
yea ill never run them agine, i seen on hp tv they did a dyno pull with an ls7an got better mpg an little more power i figured what the hell why not try them. i got NGK now i like them run them in the race car an my 4wheeler. makes me mad 6.00$ a plug lol o well
yea i no that now lol
No offense meant. Just hate to see people taken by BS advertising claims.
When I saw the title of this thread I figured this would be the result. E3 is just another marketing gimmick.
On the topic of plug designs though, has anyone seen/tried those new Pulstar plugs?? They are very expensive, but they claim big things of course.
yea they will tell u what u want to hear so ull by it, im just sticking to NGK
Have had zero problems with my autolites, NGKs are a fine choice as well. Those E3 logs are right up there with Weapon X's. Which is a very bad thing.
For most of us who drive the cars on the street. Any sparkplug that is changed often enough will do the job just fine. If you have the extra money to spend on premium plugs, go for it. If you have good results or bad let us all know.
As for the marketing gimmick:
We all have some kind of personal preference for certain brands. Marketing people know this. They see this as a sign that marketing works. If it didn't work we would all by the lowest priced product. Consumers are willing to pay more for a difference in the product, whether that difference is real or just BS.
I personally would avoid any product recommended by a host on a show that is sponsored by that product. They have an interest in that products success. Just my .02.
I rarely ever pay attention to market hype. I don't mind going out and trying new products. I like to experiment whether people say it's good or bad. I've found mixed results.
As far as plugs I had the luxury of experimenting on a dyno one day. We found the NGK's never really made any difference in exhaust gas temps when changing heat ranges.
Not that it's a bad plug, I'm sure they work. We just weren't impressed with colder heat ranges having no affect on cylinder temps. Generally one heat range changes temps about 30 degrees. Didn't see that with NGK's.
On the other hand, the Autolites performed perfectly in this mannor. For that reason alone I switched to Autolites.
I've also been a fan of ACdelco plugs. But unfortunately they don't offer colder heat ranges for the LS1 with these long .708 reach plugs they use. So that cans ACdelco's for me as far as LS engines go, or any aftermarket aluminum headed engine that requires the long reach plugs.
ACdelco does however still offer colder heat ranges for the old 1/2 inch reach plugs used in older engines, in which they work fine, and I still use them in those applications.
anyone ever try the bosh platinum 2 or 4? i have a friend that swaers by them says there the bestplug he had. idk maybe its just me, bu ti thik its all over rated. i would like to see a test where they try all these plugs an see what the results are
I am willing to bet the misfire wasn't the E3 plugs you put in now that I saw your other thread about the cam install.
Get your car tuned before putting in A GOOD plug in. Get AutoLite AR103's once it is tuned.
And never use a plug with more than one 'prong' or whatever they call it.
Bosch is terrible.
Plugs are plugs. If they spark, that's all you need them to do. A "small" spark can create the ignition u need, just like a "big" spark.
Cause the more protrusions u have in the way of the air/fuel mixture, the less chance u have of getting a "good" ignition.
No, it can't.
A better spark will create more complete combustion and therefore more power and better fuel economy.
A shitty ignition system will not have the power to run a performance engine. Weak spark causes power loss, misfires, and higher emmissions, which is a lose-lose. You want a high voltage spark with a large flame front, which is why our engines use 8 individual coils and have a stock gap of .060".
There is so much information on spark plugs you could be reading for hours. Heat range, manufacturer, electrode gap, electrode materials, ect. Just because it makes a spark doesn't mean its efficient or ideal.
Thanks Wes, I wasn't sure I felt like typing all that,,,lol. There is so much to spark plugs it's almost boring to some people.
There have been books about plugs, and plug tech going back as far as "Smokey" which makes for some very interesting reading.
Reading some of it will make ya think twice before just throwing in any old set of plugs you can find on your next tuneup.
I've used tons of different plugs and the main difference will be in the heat ranges and how fast they foul up. I've used all the iridiums and the +4s etc and theyre all the SAME because they all do the same job.
A lot of people change worn and fouled plugs with new ones and whichever brand they choose they tell everyone 'OH WHAT A DIFFERENCE'. It's really a difference between a worn/fouled vs new they're just too stupid to realize.
Now im my personal opinion the plugs that stayed the 'cleanest' or at least were at the best heat range in my stroker motor were Nology Silvers. Odd I dont think theyre available anymore but when I was swapping and checking plugs often on the same tune they really stayed clean. They all worked just as well to the sotp meter:snowboard:
I guess I should have said they all perform the same function instead of 'they are the same'. On a stock motor the slight differences in heat range will not be noticeable.
Many times I have seen people say their cars stutter and dont idle as smooth with certain 'gimmick' plugs and when I pull the plugs and check them its because the gaps were wrong.
Sound like some of the members on here have a lot of knowledge on spark plugs. For a 2002 with a few bolt ons what plug would you reccomend?
Shouldn't notice a difference between any plugs as long as you got the proper heat range for you application.
And didn't buy into the gimmick plugs.
Simply put...plugs are a maintenance item.
If you replace your brakes with OE pads before they are worn, you shouldn't notice a change in the braking power.
Same goes for plugs. They are NOT a performance part.
Although there is performance to be had. Ever heard of indexing?? Something that Smokey found in the 60's.
Washers are made for this, to get the open end of the electrode facing the top of the piston, for better flame travel. Another trick is to cut back the ground strap to expose some of the elextrode,,,also promotes better flame travel. The Autolite race plugs come this way. But it's easy to trim them back on your own, I generally do this myself.
Heat ranges play a big factor,,,and can soley be used as a tuning tool...
Ever change heat ranges and watch your wideband change?? Heat ranges can make differences in what you run for timing tables, fuel mixture or (AFR) as well.
These little tricks I mentioned affect even a stockish car.
ok there a lot of people on here that would recommend autolite. i was online looking at them and i found fram autolite. now are these the same?
i would have to guess no since the price difference is so drastic but i thought i would double check
thanks for clearing that up for meQuote:
What you found is that FRAM is a division of Autolite. Has been for many years. They are both owned by Honeywell. As is Bendix and Prestone.
just a few bolt-ons thats itQuote:
Fram Autolite?? Never heard of that...
What is done to your car?? If you are changing heat ranges, Autolites can be beneficial. For a stock or bolt on car, I'd go with AC Delcos any day of the week.
thanks for the advice:thumbup:
Yes, what he said!! :)
Some people like NGK's as they find them easier to read, I like Autolites, been using them for a long time in multiple applications.
Spark plug indexing does give you a little more power, specially in higher dome smaller or less efficient combustion chambers. It is easy HP! :firedevil:
NGK TR55 work good for me.
I figured out what the miss was in my motor, I had 2 bad o2 sensors an they weren't sending a single to the computer. I changed them out car runs great (without a tune) I'm not running it hard by no means but I'm getting it tuned today so I can't wait to see how it pulls!
