I've noted some ads for E3 spark plugs claiming all the same stuff quicker starts, better fuel econ, is this the same old 1950'60's technology rapped up for new customers or are ther good as said? Cars,trucks, chainsaws, lawnmower .

I use E3's in all my small engines- lawnmower etc.
I have had good luck with them. I have not tried them in a car, truck or tractor.
 
If you install E3 spark plugs and you notice an improvement, it's because you had problems with your old spark plugs, period.
 
They do work but as stated most likely you needed a new plug. With most all of my engines I have had very good results with NGK or Denso plugs. The NGK copper core plugss or the other one try the palladium plugs in your higher end engines like vehicles. Both of my garden tractors with 21/22 hp engines have those plugs. The Japanese engines just love those plugs. Portable air compressor ,chainsaw, tracvac, and the tractors all have NGK.
 
Yeah, I like NKG too I've had good luck with Autolite copper (216) in Kohler engines. But one never knows.....something new may be better but this looks so much like the old JC Whitney 4 electrode plug from the 1960's.
 
E3 has a great ad campaign but I doubt most of their claims. It's just an over priced spark plug with a fancy shaped electrode. Use a brand name spark plug, ensure it is clean and properly gapped and your engine will go BANG. :)
 
Hello jack345,

I use them cause they work! I had one engine so flooded it took a dozen slow pulls to get it to turn.
After a few pulls and gas puffing out of the exhaust, the engine with an E3 plug STARTED RIGHT UP!. Believe it or NOT,

GUIDO.
 
The design is nothing new. Piston engines in aircraft have been using the same design for decades. I use a lot of different plugs and have good luck with some and not so good luck with others. I do not buy any plug made by Champion anymore. Never get good service out of them
 
I work as a small engine technician. I rarely see an engine running well with an E3 plug in it. And in about 5% of the cases, it seems the E3 plug is the only problem.

I do work on Husqvarna equipment and some of their ignition modules do require a resistor spark plug in order to time the spark correctly. I don't have any source for info on whether the E3 plug that the customer got from Lowes or Walmart is the correct one for the engine or not.
 
Anybody remember Western Auto? They sold a plug the looked just like the E3 in the 70s. About 20 years ago, the manager at the local O R store told me he had every set he sold,had been returned.
 
Oh I can remember those things! Friend bought a set for his VW Giha. Think they were made in England. Didn't last too long. Remember how every VW part in that catalog promised 10, 20, or 30% increase in power!!
 
I put a set of E3 plugs in my 2000 Nissan Frontier 4 cylinder at 76,000
miles. Sold it about a month ago with 154,000 miles with no
problems. They didn't increase the gas mileage.
 
Can anyone explain how Champion can stay in business with all of the crappy spark plugs they make.
 
(quoted from post at 04:55:55 02/13/17) Can anyone explain how Champion can stay in business with all of the crappy spark plugs they make.

I'd like to add.
Why/how did Champion go from a good spark plug to a crappy one in the '60's ?
 
I haven't bought a Champion plug in probably five years but I've got 2 Farmalls, 5 garden tractors, tiller, generator and the only trouble I have is with my 2 cycle junk, snowmobile, trimmer, and chainsaw. Car and truck are A/Cs, rest are Champs.
 

I am quite sure Champion company was bought out in the 1970's or so.

My experience related to a yard-sale spark plug cleaner/tester. I telephoned Champ and reached a great guy in customer service. he was familiar with the model of tester I had and was happy to send me parts I did not even know I needed. As I recall, he said the company was being taken over and his department would be reduced, with old "antique" parts eliminated. He sent me quite a pile of NOS parts at low prices.

I said all that to say that Champion changed in the 1970's or so and may not have recovered.

I pretty much use Champion D21 in all my tractors, Autolite 386 (?)
make my JD "B" start quicker , no change in performance...
 
I have used E3 plugs on a couple of lawn / garden engines, and in both cases, the E3 plugs fixed problems with the engines that several brands of conventional plugs would not fix.

My introduction to E3 was when I bought a little Ryobi 2 cycle string trimmer from TSC.
This little trimmer seemed to run rich at our altitude and would foul the plug to the point of no start after a couple hours use. The trimmer carb had no external adjustment so I could not lean it out a bit to try to eliminate the plug fouling. I tried several other brands of new plugs of the correct heat range with no improvement of the fouling problem.
TSC had the E3 plugs in the lawn / garden parts dept, and what caught my eye was the claim on the E3 bubble pack that they had a money back guarantee if they fouled. I asked the TSC manager if he would honor that money back guarantee, he said he would. I put that E3 plug in the Ryobi trimmer and it never fouled, in fact that plug wore the trimmer out.

My second success with an E3 plug was another engine with trouble that was not an easy fix.
It was an old Roper ride mower with a twin cylinder B&S engine with weak ignition. When I bought it, the mag spark was so weak that the only way to start it was to close the throttle to idle to lower cylinder pressure and nurse the choke until it would struggle to life. If I tried to start it with the throttle above idle, cylinder pressure was so high that the weak spark could not fire it. Also at full load, one cylinder would miss fire with the weak spark.

I suspected the problem had to be a bad mag coil, as cleaning the flywheel magnets and correcting the mag air gap did no good. I spent the $35 for a new coil, as I was about sure that was the problem. I was wrong, the new coil improved nothing, spark was still weak, so I suspected weak flywheel magnets. I also tried several brands of conventional spark plugs thinking that might help, it did not.
Remembering how the E3 plug had fixed the little Ryobi's problem, I wondered if these "magic" plugs might help the weak spark problems of the Briggs. I thought that was worth a shot before spending the money to replace the flywheel to improve spark with stronger flywheel magnets. I bought the correct E3 plugs for the Briggs and gave them a try. They totally changed the behavior of that engine. I could now flip the throttle wide open, pull the choke and it would instantly light off with a roar. It also cured the full load misfire. Before seeing how they fixed the problems with these two engines, I would have called the E3 plugs, snake oil, but no more, there really are magic spark plugs, LOL. :)
 
Were they possibly Splitfire plugs with the forked side electrode ?? I remember those. Also the JC Whitney "fire injectors" a sort of surface gap plug with no side electrode. I still have a set of those and a vintage JC whitney ad for them fastened to the wall of my shop. :)
 
Thanks Jon, think I'll try one in an old chainsaw I have & just ....MAYBE it will change its bad habit .
