plug poll

[rottenronnie]

I understand between 10:00 & 2:00

That is correct...

Here is one of many articles and has a couple of photos to illustrate...

its jsut a preference thing on plugs I guess,

I know for years I have allways gotten better service out of the ngk plugs and I know I refer to my race bikes all the time, but thats what we did for 0 years but we allways got more hp longer with the ngk plugs over champion or nippendenso


on how long a service interval............to me I suggest every ten thousand on the plugs, I knwo I could replace mine and get a noticable difference, but now fatjack never changes his and hasnt noticed anything wrong.

now tnviper talked to me one day and a shot in the dark changed his plugs and could actually "feel" a difference,

I am hoping with the new coils that the intervals will be longer between changes.

the new coils take the spark higher into the rpm where the oem coils dropped off so they kinda starved the plugs for juice

Agreed Tony Mahn..

I think Champion is still getting away with using 50 year old plug technology.

10,000 miles is a good time to pull them. The plugs don't misfire when they are shot like they used to in the old days because the ignition systems are so much more powerful than they used to be. Now the plugs just slowly go away and it is tough to notice it (until you change them that is) and realize just how bad they were...

I don't know if the new coils develop a more powerful spark, a longer duration spark or both.
We should be able to gap a bit wider, which of course is a good thing.
And the boosted guys or those running higher compression NA (esp. at sea-level) should really benefit from the new coils.

Wouldn't useing E3 plugs eliminate the need for indexing:dontknow:just an idea.

Yes they would.
I have a friend that has just completed a build and he is using them.
I don't have any feedback (yet) as it is cold and snowing there/here.

I used to be a firm Champion plug user for many years.

During the time I had the carb and fuel injection shop.
I had a 435HP 68 BBC Corvette with a lot of head work, big hydraulic camshaft and a little more compression than stock (12.5 to 1).
I ran champion plugs in this motor from the time I built it until a friend that owned a Jensen Healy shop across the street gave me a set of NGK plugs to try. I complained that I would not put a Japanese plug in my American hot rod. So I just put them in the plug cabinet & forgot about them.

I had to replace the Champion plugs about every 800-1000 miles because I would start to get misfiring at high RPMs, usually over 5500RPM. (This was in the days before we had good ignition systems).

I had this set of BP6ES NGK plugs that he had given me in the plug cabinet. (I stocked over 1500 plugs in inventory).
I had just driven to LA in the Vette about 450 miles (on new Champions) and got stuck in freeway traffic. The motor was running like crap and I knew that I had killed a another set of plugs.
I finally said what the heck I'll try the NGKs, the results were remarkable, I finally changed them out at 8000 miles. The reason to change them was not due to any misfires just the fact they had been in the motor so long I just felt guilty about it. This really opened my eyes to how much better the NGK was than what i had been using.

This is not to say that Champion makes a bad product, they have gotten better in the intervening years from what I understand.

I tried the NGKs in other high compression hot rods and the results were similar. Much longer life and virtually no short term plug failures that I had been having with the other brands on a regular basis. Out of every four sets of eight Champion plugs I had one plug fail immediately or very shortly after installation.
Also about the same time I had started using Autolite plugs with good success. For the remaining 15 years I had the shop, I stocked and used NGK & Autolite plugs.

As far as the customer was concerned it was not a part failing it was my work failing. NGK plugs made me look good, gave the customer a longer service life and a "better" running vehicle.

Just my 2 cents.
In most grocery gitters I used Autolite platinum plugs with very few problems and in high performance applications I used NGK.

This is what I was wanting to hear. Saying it ran better with brand X is an opinion....Jack placed facts on the table when his car went 10+ times as far on the NGK plugs vs Champion.....

lets see ,,,i have a set of e3,s a set of champions,and a set of nkg,s ,,,,ran all three ,,,cant say i seen any diff in any of them ,,,but i must admit i never did a long milage thingie with them ,,,i think i had a bit and i mean a tiny bit better mileage out of the e3,s though ,,,but with the e3 on a dyno it tanked at 5600 rpm,,i went back to champion dynoed the next day it pulled to 5800 or so ,,,:dontknow: i think the coils would help the e3 big time cause of the setup ,,,i think i may try to do a spark comparison after i get coils ,,,maybe try to take a picture if i can get it !!

 

[Cruster]

Back in the track days we would get a lot of plug failures from Champions, by that I mean that a least one of the 8 would not work properly or misfire for whatever reason.

Most of the guys changed to other plugs....I switched to Autolites and had no more problems. Been running them in everything since, now using the platinums.

I have no experience with NGK's but I plan to soon. The Autolites are the only ones that survive my hopped up Harley for any length of time, but I've been given high hopes for the NGK's after reading all your posts. But I'm also leaning toward no indexing, which I always believed in and did but thought was a PITA.

I'll be talkin to Tony soons he settles on somethin.

got an email today they should be getting in about 15 sets of coils friday the 15th.

between now and then I will put together a few packages including ngk plugs

I probably should do another poll, but not gonna take up any more thread space jsut for this, but

you will have your choice of

ngk 3271 double platinum

ngk 6441 IX irridium

ngk 7100 gp platinum

ngk 6987 v- power


and maybe for some lucky souls that like the E3 plugs also

I will do a thread on the packages, and options for you to choose from

What about the NGK 6855 (ZFR7F-11) V-Power. They are one step colder from stock, for us F.I. guys.

 

[JTS VENOM PERFORMANCE]

yes if you watn a custom plug I will try my best to help you,but I come up with a 6987 for oem plug

An unaltered engine will run within the optimum operating range straight from the manufacturer, but if you make modifications such as a turbo, supercharger, increase compression, timing changes, use of alternate racing fuels, or sustained use of nitrous oxide, these can alter the plug tip temperature and may necessitate a colder plug. A rule of thumb is, one heat range colder per modification or one heat range colder for every 75–100hp you increase. In identical spark plug types, the difference from one full heat range to the next is the ability to remove 70°C to 100°C from the combustion chamber.

The heat range numbers used by spark plug manufacturers are not universal, by that we mean, a 10 heat range in Champion is not the same as a 10 heat range in NGK nor the same in Autolite. Some manufacturers numbering systems are opposite the other, for domestic manufacturers (Champion, Autolite, Splitfire), the higher the number, the hotter the plug. For Japanese manufacturers (NGK, Denso), the higher the number, the colder the plug.

Yes Stank man, I get that. The NGK 6855 (ZFR7F-11) are on step colder than the stock Champions. That's what I'm running. Just thought you would want to offer this plug to the FI and probably the NOS guys in a package.

 

[JTS VENOM PERFORMANCE]

honestly Santeen i wish I could, but it will be easier on me just to list the oem plugs and if someone wants a different heat range plug than what is listed they will have to give me the number, i truely do appreciate the thinking,
but Iwould have to list adn look up a ton of plugs, and heat ranges, this way really, it will be a little easier to do, besides, I'm lazy

I think that the E3's should work real well with the open end withthose coils:rock: ,I'm gonna be one that will be using the E3's (plug# E364 for FI) with Stinkers coils:burnout: ,thanks for the input Ironhead,I'm kind woundering if what your saying about the E3's falling off at 5600RPM isn't a sign of how week the stock coils are:dontknow: ,if they get better fuel milage thats a good sign that they are burning more of the fuel in the cylinders:rock: which means more ponies:elefant: :itsme:

When I worked at the part store years ago went to a show about spark plugs and Bosch plugs just performed better but I like the NKG too

 

[bigike]

For those that use NGK...why??........is the reason factual or just "seat of paints"??????.........just wondering what makes the NGK better....I have Bosch which seem fine to me but maybe I should use NGK next time?...

Larry, when i worked auto parts there was a reason that those supers were only 79cents per plug. They were the first to fowl out. I used them in a 2 stroke once, switched to a iradium the iradium lasted at least 10 times as long. But aren't the iradum and ngk r's supposed to handle boost better?

 

[Cruster]

If you look at the E3 website they have some vids there where "Horsepower TV" the hot rod show does an A/B comparison between E3's and the "next most popular performance plug" So they don't say which plug they are comparing to but they do dyno the E3's and they seem to have some advantages over whatever they are calling the "next most popular". Next most popular or whatever could mean anything.

Anyway, it was interesting to see the testing if anyone is interested.
