I've used Iridium plugs in every gasser I've owned and a performance increase was definitely noticed. Quicker starts, smoother idle, smoother running, better fuel economy. Highly recommend.
That depends on what type of ignition you are running. In older cars with older ignitions that especially may not be the case. A LOT of how well a spark plug works has to do with what you have upstream from it. Your gasser may run just a great with NGK race plugs or even the old Autolites many drag racers used years ago. Why would you care about fuel economy in a race car??? Or is it NOT a true gasser and just a street wannabe drag racer??? Now I see where you are coming from. You sound like one of those guys that read the label on a can of VP race fuel where it states "MORE HP" on the side and think that you will get more HP just by using that fuel in your car. Or remember when you were a kid and stuck a playing or trading card into the spokes of your bike with a clothespin to make the engine sound??? You knew for a fact you were going at least 10 MPH faster with that card in there because of the sound!!! It don't work that way pal.....
Many years ago I owned a Mk2 VW Golf GTi. Shortly after buying it I took it in for a service at the local VW garage. When I got it back there was a very noticeable drop in the performance of the car so I called them up and asked them what kind of plugs it had in it and what they had replaced them with. They told me it had triple electrode plugs which they had replaced with single electrode plugs. I went straight to the nearest accessory shop and bought some new triple electrode plugs and replaced the singles, and lo and behold, the performance was right back where it was before the service.
I had a Mk3 gti as well the same happened even to me, after that I just changed it to triple ones and it fixed the problems. I'm driving a mini Cooper S now and I'm thinking of buying triple boch spark plugs because I'm having issues with single and double electrodes spark plugs.
I bought a three electrode for my motorbike(2016) It didn't show much difference so I bought a supercap to go with my battery. That made things feel a bit smoother and better start. I lent my bike to a friend and started it for him. He didn't notice and pressed the starter multiple time. That blew the stator and I got that changed to a more up-to-date one. Then I noticed a big difference and I got a few more mpg. I put a triple for my wife's scooter(2019) and she noticed a difference straight away. Her mpg went from 72 to 80. I bought a dual for my RTR 200(2019) and it runs smoother but my mpg has gone down. 82 to 79mpg.
Thats because its a gimmick, electricity will always follow the path of least resistance. That means it will only spark across one gap, that had least resistance. Maybe just .0005 closer than other .
I have used 3 electrode heads irridium spark plug , my motorcycle climbing was magical , the performance and efficiency totaly improved and get better .
The Mercury 6 cylinder 2 stroke outboard motors we used to race in the seventies had plugs without a side electrode. They were of the "surface gap" type, where the spark jumps from the centre electrode directly across to the body of the plug, effectively using the whole circumference as an electrode.
I race 2 stroke drag boats and we still use the center electrode plugs....the last forever, don't foul and there is no worry of dropping the ground strap and wiping out the cylinder. Down side is we can't read them for tuning and use standard plugs for that.
Many years ago I ran Bosch super 4 plugs in my 1.6 mazda and ran them as far as they would go. They lasted nearly 90 000 odd kilometers before they started misfiring.

My 2000 GMC 3/4 ton I bought used has about 180K miles on it and it was running perfectly, but since I didn't know when the plugs had been changed, I decided to change them. I was amazed that they were the original plugs. I had never seen plugs so utterly worn out, but the engine ran perfectly with them. I replaced the old plugs with iridium plugs. About the same time I changed my motorcycle's multi electrode plugs for iridium plugs since they were due for a change. In neither my truck or my motorcycle did I notice even the slightest change in mileage, the truck ran exactly the same with the new plugs, but my motorcycle seemed to start easier and run a bit smoother in its mid range. Single electrode Iridium plugs make all the other types superfluous in terms of their long, long, long service life with no change in performance, so why even consider multi electrode plugs with their fake promises?
Single electrode plugs are the best. I'm using the Bosch Super 4 currently and found that my car's fuel consumption increases compared to ordinary single electrode plugs used before. I'm planning on going back to single electrode plugs after this
This test does nothing but show the coil producing the spark can jump the plug gap in atmospheric pressure. It doesn't show if different styles of spark plugs make a difference in engine performance. In order to see if different style spark plugs make a difference in engine performance is to put those plugs in a cylinder that's under pressure and air/fuel mixture.
Whether or not the spark will jump the gap in various conditions is dependent on the energy put out by the ignition system and the size of the gap, not the plug or number electrodes. Also, the point of this demonstration is the fact multiple electrodes serve no purpose, because the spark will always jump the short gap and there will Always be a short gap. Multi electrodes is a scam and Always has been.
I've got my Dad's old AC aircraft sparkplug cleaner tester that uses compressed air from your air compressor to clean plugs with blasting media and to test sparkplugs under pressure, to somewhat simulate firing under compression. I haven't used it to clean plugs much because I don't have much of and don't know exactly what kind of media it's supposed to use. That and with unleaded fuels nowadays our ground vehicles don't get the lead buildup anymore the machine was designed to clean. It works alright for testing though, as I've found many bad & fouled sparkplugs with it. Anyway I've tested some E3 plugs with it and they test similarly to what we've seen here. I'd say multiple ground electrode plugs may be alright in that they may last a bit longer because when one electrode wears back the spark would then jump to a different one and so on as they wear back and keep the gap more consistent. Otherwise I don't see a significant advantage with them. IMHO
Zero electrodes. We had an old machine that burned a little oil in one cylinder. The mechanics cut off the side electrode and called it an oil plug. Never had a problem with misses, using a conventional coil and distributor.

I was looking for this kind of comment as I didn't want to repeat it. The methodology shown in this video sucks. I don't say that conlusions are wrong, we don't know it. May be wrong or good, the autor didn't check and convince us that we could extrapolate this test conditions to much higher pressures, surrounding gases and temperatures. What may be noticed - the shape of single electrode causes the plasma arc to be hidden behind of the single electrode, when shape of multiple electrode makes the plasma arc exposed to the cylinder space more. Probably neglible influence on ignition.
Toyota's A series and S series engines, which were launched in the 80s with distributor were upgraded in the 90s to twin coil pack system. This meant one coil firing 2 cylinders, so even the cylinders that are not in the ignition cycle were ignited, in other words spark plugs were firing twice the number of times compared to the distributor system. So Toyota did specify twin electrode plugs on these engines to prolong the life. I had those engines converted to run on LPG. I tried putting platinum plugs to see and it did misfired from time to time. When twin or triple electrode spark plugs were used, never misfired. This is to do with LPG being difficult fuel to ignite in contrary to popular beliefs. Somehow the very thin platinum plugs' firing tip didn't quite cope well with those engines. That said, years later running a much modern Mazda L series engine which has one coil per cylinder as with most modern cars, this engine runs well platinum plugs even running on LPG. So the bottom line is, multiple electrode plugs do not necessarily give performance but do give reliable sparks and durability. However these factors are not much of an issue as platinum and more lately, the iridium plugs have covered these areas which conventional plugs struggled in the past.
I used Bosch twin ground electrode plugs in my Mk4 Astra several years ago as that was what Vauxhall recommended. They worked fine with no issues. Personally I don't see a need for multi ground electrode plugs - their claim of a more reliable/stronger spark is negligible (at best) Iridium or Platinum single ground electrode plugs are ideal.
I used 4 electrodes Bosch in a k11 Nissan Micra 1.0 16V. It worked out perfectly but there was no increase in the performance either. It was the same as with the single electrode ones.
My Honda Civic 1.5L came with single ground electrode spark plugs. I routinely get 50mpg in the summer months. At 100k miles I switched to triple electrodes, and my mpg went down 1-2mpg. I put the old spark plugs back into the engine, and my mpg has returned. The results don't lie.
You have to drive a while for the computer to detect and adapt changes or you can reset the computer after the mod. I had to change the spark plugs because they have never been change in a Honda Fit. No difference to Bosch Platinum from stock. But then At around 55MPH there was a slight speed bump that was not there before.
The manufacturers of these "super duper ultra high performance space shuttle" spark plugs know that if you put that on the package for potential buyers to see they will believe it to be the absolute truth and spend the big money for them when in reality the product is no better than the OEM plugs. When my son was racing motocross we bought an '06 Suzuki RM 125. That bike came with an NGK spark plug that costs $22 back then and I absolutely refused to pay that so I bought the good old NGK B8-ES that just about every 2 stroke single cylinder motorcycle came stock with for the last 40 years. Absolutely no difference in performance, he still won races, and the plug color was perfect. I owned a 1970 340 'cuda most of my life and the best plug for those engines recommended by guys that raced 340 Mopars was an ancient Autolite plug (forgot the number) that had been around for years. Even the modern day 5.7L Hemi's, I had a few, are said to run best on good old Champion copper core plugs. Sometimes modern technology is not that great....
I half gap conventional plugs and get a noticeable gain. Its all about unshrouding the spark and eliminating indexing. (Look up side gapping) Years ago I compared brand new factory type plugs in my turbo 2.3 then Splitfires and there was a noticeable difference. The last 25 years I half gap and easily get 25k+ service with these '90s high energy ignitions. Other installations using MSD boxes are amazing.
I use single electrode spark plugs myself. I always index my plugs where the gap is open @ the intake valve it makes a difference, time consuming a V-8 takes 64 tries to get it right but any old school racers will contest it works.
Bosch 4 électrodes depuis de nombreuses années sur toutes mes voitures. Démarrage été et hiver au 1er coup de démarreur, consommation réduite, ralenti stable, pas d'encrassement des bougies, légère usure apres 100 000 km, et surtout constaté sur toutes voitures comparé à la simple électrode, une souplesse en 1ere 2e et même 3e vitesse quand on roule sur un filet d'air, pédale complètement relevée, on repart en souplesse quand on remet les gaz. Alors Oui...Vive les 4 électrodes !
Multi electrode plugs tend to be favoured by manufacturers where a twin cam engine has a high rpm frequency vibration issue, as a single long electrode can fracture and break off. Also, as you mention multi electrode plugs can "quench" the spark with increased metal area and then engines are more likely to fail the idle emissions tests by not running as smoothly.
Currently run Multi Electrode plugs with my CDI Ignition, They DO Last longer & give Better throttle response from my experience. With that said, If the plug wires or any other ignition parts are wore out or just low quality then Nothing is going to do you any favors until All other ignition flaws are worked out.
Wow wonderful experiment i ever seen on Spark plugs, great. in my experience i used single and double electrode spark plugs for my motorcycle, i found no difference yet, both are same power. Single elect ahows a little extra mileage too. Its our myth that that more electrodes can offer more power.
I've always disliked multiple ground strap plugs. You can't create multiple sparks at one time. They simply wanna sell you some they're gonna convince you that you need. I went to try the e3 plugs one time. And right away noticed they're non adjustable as far as gap goes. I needed a .035 gap for my C/20. I ran em and noticed at high rpm I'd have an odd misfire feel. I took em out, and used a dremel to cut 2 of the 3 ground straps off. With that outta the way I measured the gap. .045! Huge gap, no wonder the misfire. With the remaining ground strap I adjusted it down to .035. And they ran very well after that mod. Lotta money for plugs I gotta fix myself in my opinion. Standard plugs are the best you'll get out there.
Mercedes uses two plugs per cylinder and the spark from each plug is staged to ignite sequentially so you get more complete burn of the mixture. Each plug connects to one coil pack that has two separate windings. The staged burn is controlled by the ECM. I believe Hyundai recently patented a double center electrode spark plug which would be similar to concept of two separate plugs in that each electrode would be ignited sequentially from its own coil pack.

I haven't used it to clean plugs much because I don't have much of and don't know exactly what kind of media it's supposed to use.

I am currently using NGK triple electrode, and i am very satisfied. They were roughly 6€ a piece. Car is gasoline Lancia Kappa 2.0 5 cylinder VIS engine 114kw.
Side note, most aircraft piston engine spark plugs use multiple ground electrodes like this. It could be similar to why most aircraft systems are redundant, have backups. Av gas still has lead in it, but they are currently working on developing and changing to unleaded Av gas, so multiple ground electrodes might help keep the plugs firing as they get built up with lead deposits. IDK for sure here, I'm speculating on that...
I was going to post the same thing, but of course spark plugs in the aviation industry are called igniters. Plus aircraft engines have 2 plugs per cylinder.
In my 2001 doge ram 2500 iridium plug was worst seems missing on plugs, after change to E-3 spark plugs seems No more missing on cyl and better starts and operation of vehicle
I tried a set of Bosh 4’s in the 90’s, it ran a little rough, not so bad it was misfiring just not as smooth so I went back to a single cathode plug and it was fine. I figured I must have gapped them incorrectly but the fitting feeler gauges were the same, no idea why.
These days, unless you have a modified engine or a problem with your engine such as too much fuel injected or oil fouling, the OEM spark plugs should last at least 100,000 miles unless you do a lot of hard towing or similar duty. Over the years I have learned that if the spark plug produces a spark in the cylinder for 99.9% of it's events that's all you can ask for. All of the other specifications like heat range has to do with other things but if the spark happens the fuel will ignite if all else is correct. Stick with OEM plugs because there are no miracle spark plugs. Just like no engine rebuild in a can or that natural cure in a pill form sold on the radio and late night TV.
Isn’t the effect they are going for with side electrodes is to give the spark unobstructed pathway to the gas? An old trick drag racers used back in the day was to trim the ground strap back to expose the hot electrode spark without the ground strap blocking it. Multiple grounds would help with the wear caused by the spark hitting the edge of the electrode and burning it down faster, multiple grounds would spread that faster wear around the whole perimeter of the electrode
Not really sure if extra electrodes are really necessary when someone has invented a dual spark ignition system. Perhaps combining dual electode spark plugs with a dual ignition that precisely fires each electrode with ignition circuit could eliminate the need for pollution devices like catalytic converters and/or EGR valves. No reason to say a triple ignition system combined with triple electrode SPs could be created but that would probably be more useful in big block V8s or high performance engines. Multiple electode SPs combined with multiple ignition systems might also make turbo-chargers more efficient requiring less maintenance and dumby proof both the motor and the driver.
I used bosch platinum plus 4 in a 92 honda civic . It felt like it added 30 horsepower. At least the car was much faster then factory. It got great gas mileage. And much quicker performance.
Different is that the time if electrode degrading is longer, as the distance between central and side increases, the second side electrode will be closer than the first one ...
Multi prong plugs maybe good for preventing fouling. But a hotter plug or finding the cause of the fouling is the best. I tried platium and didn't like them at all. Loss of power. Iridium is the way to go. If you only want to change the plugs once. I put copper plugs in my hemi and took out the iridium plugs. After 30k miles when I have to change them again I am putting the old plugs back in. And never have to mess with them again.
A faísca vai promover a ignição, então use uma vela de ignição adequada e boa para o seu projeto. A vela de ignição não vai promover mais força, isso você vai conseguir ajustando o ponto de ignição...
No matter how many electrodes you have, only one spark will be produced at each impulse, and it will do so in the place that finds the least resistance at any given time. Placing many electrodes only distributes Electrode wear, increases spark plug life, but does not increase power.
Yes I've used multi electrode plugs. Seemingly no difference in performance but I believe them to be longer lasting and it must prevent fouling as it ages at least somewhat. I'll switch to just twin electrodes after seeing this however. Thanks for the showing.
Have two ground Bosch platinum,can't tell any difference in engine operation but have not had any problem with either these or the original plugs (coil on plug 4.7)
I'm fr malaysia .. when used B super 4 on my 1991 c22 van 1.5L carb its feel different when driving up hill.. the tork of an engine more powerfull then i used single ground spark plug.. also used B super 4 on MIVEC 1.6L DOHC topspeed increas fr 210kmh to 228kmh (210kmh used DENSO iridium) on ron 95 fuel
No difference when they are new. But if you use them for too long the one with more ground electrodes last longer. The reason is there is only one spark at the same time, this means if you have 2 electrodes then each of them will be used for half of the sparks. So they will last longer. Hopefully you will change to new spark plugs before that happens!
In my 1972 Mercedes 250CE it eas smell from exhoust of unburned fuel so i got 4 electrode Bosch spark plugs snd thsy done job. No more smell of unburned fuel from exhoust. Thay did job right.
Are the distance between eléctrodos correct? On the pack they say yes but Im general they dont. I fell diference between One electrod and four. Less accelarion needed.
A lot of standard BMW OEM plugs are 3 or 4 prong - except for the M engines where they use single prong. So that may tell you about longevity vs performance.
No, that BMW selection 3 or 4 electrode spark plug, tell you about. Performance over longevity. ✌️ Performance = 3 or 4. Longevity =1 iridium point. Regards Sir.
@@gerardomedina333 i change my spark plugs, very very worn maybe the original ones 4 electrodes platinium, very worn all at 200.000km. i try these plugs a old carburetor car, and starts better and has more response
Whatever fun you might have: Volvo 5 and 6 cylinder turbo engines only works with original Volvo spark plugs. Unless you want to change plugs every 20.000 miles.. :-) I have owned a number of the 2.5T2's and tried to use other brands, but they just did not keep up to the 100.000 mile /160.000 km requirements,
Honestly speaking, I've used them all and the best for me is 3 electrode spark plugs. They have a bit of more power if you're running a piggy back ecu or tuned vehicle. Single electrode spark plugs are not useful if you're a daily driver and do services late due to budget.
Technically its one ground .... its not like there are 2 different channels or 3 channels or even 4 channels for spark to travel thru, its all the same piece of metal
How do you even gap those multiples? If an ignition only throws one spark per revolution per cylinder, that's all you get. Something like an MSD box will give you multiples.
Yes, the MSD will give multiple sparks and the multiple sparks will jump the shortest gap. So, even then, the multiple electrodes are doing nothing for you. There is no distribution system in the plug.
Mercedes Benz in Brazil had a Model Classe A with Bosch four ground electrodes at factory . However it was discontinued. They worked well in an ignition system of lost spark in a four inline motor. Today iridium plugs are the best truth. In turbocharged motors last longer and well ! Believe me !!! Caution with the false sellers with false products...
At any given moment there will be only one spark. There will not be two or three sparks simultaneously on three electrodes. Therefore, it will not make a difference which spark plugs to use. Perhaps spark plugs with three electrodes will work longer.
well i still do prefer single electrode sparkplug, because no matter how many electrode there is spark always just happen once in every trigger, no such thing as having more spark in one cycle, the only benefit i saw in multi electrode is,. longetivity, more electrode to eat up means longer time to perform, but in performance i choose single electrode for the sparks mentain the certain point of location in whiche the burning of mixture happens and it is baoance as to it being at the middle and consistently at the middle always
You forgot to mention that the multi electrode plugs can't be gapped. Might be ok on newer engines, but it is critical on older ignotion systems for the longevity of the coil, points, and condenser. Too much gap will cause shorter part life because of the extra energy needed to jump a longer gap.
They will literally work the same when the spark only occur once even with multiple feet. I was just curious about how multi electrodes with multiple feet works
My ex boss had a Hemi Stock Eliminator race car and tested spark plugs on the Dyno. The multi. electrode plugs made 0 h.p. more than the single electrode plugs he was already running. If you have a efficient firing system the amount of electrodes does'nt matter!

May be wrong or good, the autor didn't check and convince us that we could extrapolate this test conditions to much higher pressures, surrounding gases and temperatures.
What may be noticed - the shape of single electrode causes the plasma arc to be hidden behind of the single electrode, when shape of multiple electrode makes the plasma arc exposed to the cylinder space more. Probably neglible influence on ignition.
The biggest difference should probably be that the spark gap is horizontal or vertical should affect how the fuel mixture is ignited.
Toyota's A series and S series engines, which were launched in the 80s with distributor were upgraded in the 90s to twin coil pack system. This meant one coil firing 2 cylinders, so even the cylinders that are not in the ignition cycle were ignited, in other words spark plugs were firing twice the number of times compared to the distributor system. So Toyota did specify twin electrode plugs on these engines to prolong the life.
I had those engines converted to run on LPG. I tried putting platinum plugs to see and it did misfired from time to time. When twin or triple electrode spark plugs were used, never misfired. This is to do with LPG being difficult fuel to ignite in contrary to popular beliefs. Somehow the very thin platinum plugs' firing tip didn't quite cope well with those engines.
That said, years later running a much modern Mazda L series engine which has one coil per cylinder as with most modern cars, this engine runs well platinum plugs even running on LPG.
So the bottom line is, multiple electrode plugs do not necessarily give performance but do give reliable sparks and durability. However these factors are not much of an issue as platinum and more lately, the iridium plugs have covered these areas which conventional plugs struggled in the past.
I used Bosch twin ground electrode plugs in my Mk4 Astra several years ago as that was what Vauxhall recommended. They worked fine with no issues.
Personally I don't see a need for multi ground electrode plugs - their claim of a more reliable/stronger spark is negligible (at best)
Iridium or Platinum single ground electrode plugs are ideal.
I used 4 electrodes Bosch in a k11 Nissan Micra 1.0 16V. It worked out perfectly but there was no increase in the performance either. It was the same as with the single electrode ones.
My Honda Civic 1.5L came with single ground electrode spark plugs. I routinely get 50mpg in the summer months. At 100k miles I switched to triple electrodes, and my mpg went down 1-2mpg. I put the old spark plugs back into the engine, and my mpg has returned. The results don't lie.
You have to drive a while for the computer to detect and adapt changes or you can reset the computer after the mod. I had to change the spark plugs because they have never been change in a Honda Fit. No difference to Bosch Platinum from stock. But then At around 55MPH there was a slight speed bump that was not there before.
The manufacturers of these "super duper ultra high performance space shuttle" spark plugs know that if you put that on the package for potential buyers to see they will believe it to be the absolute truth and spend the big money for them when in reality the product is no better than the OEM plugs. When my son was racing motocross we bought an '06 Suzuki RM 125. That bike came with an NGK spark plug that costs $22 back then and I absolutely refused to pay that so I bought the good old NGK B8-ES that just about every 2 stroke single cylinder motorcycle came stock with for the last 40 years. Absolutely no difference in performance, he still won races, and the plug color was perfect. I owned a 1970 340 'cuda most of my life and the best plug for those engines recommended by guys that raced 340 Mopars was an ancient Autolite plug (forgot the number) that had been around for years. Even the modern day 5.7L Hemi's, I had a few, are said to run best on good old Champion copper core plugs. Sometimes modern technology is not that great....
I half gap conventional plugs and get a noticeable gain. Its all about unshrouding the spark and eliminating indexing. (Look up side gapping)
Years ago I compared brand new factory type plugs in my turbo 2.3 then Splitfires and there was a noticeable difference.
The last 25 years I half gap and easily get 25k+ service with these '90s high energy ignitions.
Other installations using MSD boxes are amazing.
I use single electrode spark plugs myself.
I always index my plugs where the gap is open @ the intake valve it makes a difference, time consuming a V-8 takes 64 tries to get it right but any old school racers will contest it works.
How does indexing plugs work on a 4 stroke if both valves are closed (power stroke) when the plug fires?
Bosch 4 électrodes depuis de nombreuses années sur toutes mes voitures. Démarrage été et hiver au 1er coup de démarreur, consommation réduite, ralenti stable, pas d'encrassement des bougies, légère usure apres 100 000 km, et surtout constaté sur toutes voitures comparé à la simple électrode, une souplesse en 1ere 2e et même 3e vitesse quand on roule sur un filet d'air, pédale complètement relevée, on repart en souplesse quand on remet les gaz. Alors Oui...Vive les 4 électrodes !
Multi electrode plugs tend to be favoured by manufacturers where a twin cam engine has a high rpm frequency vibration issue, as a single long electrode can fracture and break off. Also, as you mention multi electrode plugs can "quench" the spark with increased metal area and then engines are more likely to fail the idle emissions tests by not running as smoothly.
Currently run Multi Electrode plugs with my CDI Ignition, They DO Last longer & give Better throttle response from my experience. With that said, If the plug wires or any other ignition parts are wore out or just low quality then Nothing is going to do you any favors until All other ignition flaws are worked out.
thanks for this demo. I found my multiple questions at one place .. very informative
You're welcome, thanks for watching !
I used triple ground on a Harley and starting was quick with slightly better fuel economy and power.
I have tried them all in my naturally aspirated bored and stroked LS3, iridium plugs are the only spark plugs I will use.
Wow wonderful experiment i ever seen on Spark plugs, great. in my experience i used single and double electrode spark plugs for my motorcycle, i found no difference yet, both are same power. Single elect ahows a little extra mileage too. Its our myth that that more electrodes can offer more power.
I've always disliked multiple ground strap plugs. You can't create multiple sparks at one time. They simply wanna sell you some they're gonna convince you that you need. I went to try the e3 plugs one time. And right away noticed they're non adjustable as far as gap goes. I needed a .035 gap for my C/20. I ran em and noticed at high rpm I'd have an odd misfire feel. I took em out, and used a dremel to cut 2 of the 3 ground straps off. With that outta the way I measured the gap.
.045! Huge gap, no wonder the misfire. With the remaining ground strap I adjusted it down to .035. And they ran very well after that mod. Lotta money for plugs I gotta fix myself in my opinion. Standard plugs are the best you'll get out there.
Massive electrode spark plugs are more reliable - that’s why aircraft use them.
Mercedes uses two plugs per cylinder and the spark from each plug is staged to ignite sequentially so you get more complete burn of the mixture. Each plug connects to one coil pack that has two separate windings. The staged burn is controlled by the ECM.
I believe Hyundai recently patented a double center electrode spark plug which would be similar to concept of two separate plugs in that each electrode would be ignited sequentially from its own coil pack.
I've got my Dad's old AC aircraft sparkplug cleaner tester that uses compressed air from your air compressor to clean plugs with blasting media and to test sparkplugs under pressure, to somewhat simulate firing under compression. I haven't used it to clean plugs much because I don't have much of and don't know exactly what kind of media it's supposed to use. That and with unleaded fuels nowadays our ground vehicles don't get the lead buildup anymore the machine was designed to clean. It works alright for testing though, as I've found many bad & fouled sparkplugs with it. Anyway I've tested some E3 plugs with it and they test similarly to what we've seen here. I'd say multiple ground electrode plugs may be alright in that they may last a bit longer because when one electrode wears back the spark would then jump to a different one and so on as they wear back and keep the gap more consistent. Otherwise I don't see a significant advantage with them. IMHO
I had e3 plugs cause a misfire in a low mileage engine. I wouldn't recommend them to anyone.
Far as I'm concerned e3 plugs are a joke I can make more power and better mpg out of the cheapest autolite plugs, autolite has never failed me yet
Those old media blast spark plug cleaners are a no no. BAD BAD BAD for the plugs.... I doubt they even make them anymore.
I am currently using NGK triple electrode, and i am very satisfied. They were roughly 6€ a piece. Car is gasoline Lancia Kappa 2.0 5 cylinder VIS engine 114kw.
That's a good price for them !
Side note, most aircraft piston engine spark plugs use multiple ground electrodes like this. It could be similar to why most aircraft systems are redundant, have backups. Av gas still has lead in it, but they are currently working on developing and changing to unleaded Av gas, so multiple ground electrodes might help keep the plugs firing as they get built up with lead deposits. IDK for sure here, I'm speculating on that...
I was going to post the same thing, but of course spark plugs in the aviation industry are called igniters. Plus aircraft engines have 2 plugs per cylinder.
Precision gapping is tedious and limited. Spark will jump the closest gap, and as it wears it will seak the closest gap.
AP,AI, engineer here.
In my 2001 doge ram 2500 iridium plug was worst seems missing on plugs, after change to E-3 spark plugs seems No more missing on cyl and better starts and operation of vehicle
I tried a set of Bosh 4’s in the 90’s, it ran a little rough, not so bad it was misfiring just not as smooth so I went back to a single cathode plug and it was fine. I figured I must have gapped them incorrectly but the fitting feeler gauges were the same, no idea why.
These days, unless you have a modified engine or a problem with your engine such as too much fuel injected or oil fouling, the OEM spark plugs should last at least 100,000 miles unless you do a lot of hard towing or similar duty. Over the years I have learned that if the spark plug produces a spark in the cylinder for 99.9% of it's events that's all you can ask for. All of the other specifications like heat range has to do with other things but if the spark happens the fuel will ignite if all else is correct. Stick with OEM plugs because there are no miracle spark plugs. Just like no engine rebuild in a can or that natural cure in a pill form sold on the radio and late night TV.
Isn’t the effect they are going for with side electrodes is to give the spark unobstructed pathway to the gas? An old trick drag racers used back in the day was to trim the ground strap back to expose the hot electrode spark without the ground strap blocking it. Multiple grounds would help with the wear caused by the spark hitting the edge of the electrode and burning it down faster, multiple grounds would spread that faster wear around the whole perimeter of the electrode
Not really sure if extra electrodes are really necessary when someone has invented a dual spark ignition system. Perhaps combining dual electode spark plugs with a dual ignition that precisely fires each electrode with ignition circuit could eliminate the need for pollution devices like catalytic converters and/or EGR valves.
No reason to say a triple ignition system combined with triple electrode SPs could be created but that would probably be more useful in big block V8s or high performance engines. Multiple electode SPs combined with multiple ignition systems might also make turbo-chargers more efficient requiring less maintenance and dumby proof both the motor and the driver.
What a brilliant video! It's a showcase of innovation and artistic courage.
Thank you ! :)
I used bosch platinum plus 4 in a 92 honda civic . It felt like it added 30 horsepower. At least the car was much faster then factory. It got great gas mileage. And much quicker performance.
You must be totally delusional!
Different is that the time if electrode degrading is longer, as the distance between central and side increases, the second side electrode will be closer than the first one ...
Multi prong plugs maybe good for preventing fouling. But a hotter plug or finding the cause of the fouling is the best. I tried platium and didn't like them at all. Loss of power. Iridium is the way to go. If you only want to change the plugs once. I put copper plugs in my hemi and took out the iridium plugs. After 30k miles when I have to change them again I am putting the old plugs back in. And never have to mess with them again.
Single i use instead of 3 electrode denso original plug bur snall missing was in engine but it gone with single electrode ngk.
Yes, four or three electrode spark plug; It could be, the best choice you can do!
A faísca vai promover a ignição, então use uma vela de ignição adequada e boa para o seu projeto.
A vela de ignição não vai promover mais força, isso você vai conseguir ajustando o ponto de ignição...
No matter how many electrodes you have, only one spark will be produced at each impulse, and it will do so in the place that finds the least resistance at any given time. Placing many electrodes only distributes Electrode wear, increases spark plug life, but does not increase power.
Which of these is good to reduce gas consumption on a 2021 highlander
Yes I've used multi electrode plugs. Seemingly no difference in performance but I believe them to be longer lasting and it must prevent fouling as it ages at least somewhat.
I'll switch to just twin electrodes after seeing this however. Thanks for the showing.
Have two ground Bosch platinum,can't tell any difference in engine operation but have not had any problem with either these or the original plugs (coil on plug 4.7)
I'm fr malaysia .. when used B super 4 on my 1991 c22 van 1.5L carb its feel different when driving up hill.. the tork of an engine more powerfull then i used single ground spark plug.. also used B super 4 on MIVEC 1.6L DOHC topspeed increas fr 210kmh to 228kmh (210kmh used DENSO iridium) on ron 95 fuel
No difference when they are new. But if you use them for too long the one with more ground electrodes last longer. The reason is there is only one spark at the same time, this means if you have 2 electrodes then each of them will be used for half of the sparks. So they will last longer. Hopefully you will change to new spark plugs before that happens!
In my 1972 Mercedes 250CE it eas smell from exhoust of unburned fuel so i got 4 electrode Bosch spark plugs snd thsy done job. No more smell of unburned fuel from exhoust. Thay did job right.
Are the distance between eléctrodos correct? On the pack they say yes but Im general they dont. I fell diference between One electrod and four. Less accelarion needed.
The plug gaps are usually preset
A lot of standard BMW OEM plugs are 3 or 4 prong - except for the M engines where they use single prong. So that may tell you about longevity vs performance.
No, that BMW selection 3 or 4 electrode spark plug, tell you about. Performance over longevity. ✌️
Performance = 3 or 4.
Longevity =1 iridium point.
Regards Sir.
@@gerardomedina333 i change my spark plugs, very very worn maybe the original ones 4 electrodes platinium, very worn all at 200.000km. i try these plugs a old carburetor car, and starts better and has more response
I used Splitfire plugs in an old 1957 35 hp Johnson outboard, and it performed well.
It most likely performed as good as it did with the stock OEM plugs in it so why spend the extra money on those gimmick plugs....
Whatever fun you might have:
Volvo 5 and 6 cylinder turbo engines only works with original Volvo spark plugs.
Unless you want to change plugs every 20.000 miles.. :-)
I have owned a number of the 2.5T2's and tried to use other brands, but they just did not keep up to the 100.000 mile /160.000 km requirements,
Honestly speaking, I've used them all and the best for me is 3 electrode spark plugs. They have a bit of more power if you're running a piggy back ecu or tuned vehicle. Single electrode spark plugs are not useful if you're a daily driver and do services late due to budget.
Technically its one ground .... its not like there are 2 different channels or 3 channels or even 4 channels for spark to travel thru, its all the same piece of metal
Found a small difference from single point spark plugs when changed over to iridium plugs
Hi, please test the new motorcycle candles with a button tip. thank you.😊🌷

Which is better? Interms of fuel efficiency single or multiple electrodes thankyou bro
I use the manufacturer recommended type. They have 2 grounds.
Hey what is best plug for Tomos 2 stroke motor?
I'm nut sure, this site might help: www.tomoshop.nl/en-gb/tomos-spark-plug
I’ve used multi electrode spark plugs for years. I’ve never had any problems with them
I used them on a few different cars over the years and didn't really find much of a difference in performance.
How do you even gap those multiples? If an ignition only throws one spark per revolution per cylinder, that's all you get. Something like an MSD box will give you multiples.
Yes, the MSD will give multiple sparks and the multiple sparks
will jump the shortest gap. So, even then, the multiple electrodes
are doing nothing for you. There is no distribution system in the plug.
Electric sparks erode metal. It evens out.
I simulate it closer to computer hard drive back ups.. yah little to no performance improvements, but reliability in spark timing and consistency
Mercedes Benz in Brazil had a Model Classe A with Bosch four ground electrodes at factory . However it was discontinued. They worked well in an ignition system of lost spark in a four inline motor. Today iridium plugs are the best truth. In turbocharged motors last longer and well ! Believe me !!! Caution with the false sellers with false products...
Is there reason not to test a single side, as proof? Tks
At any given moment there will be only one spark. There will not be two or three sparks simultaneously on three electrodes. Therefore, it will not make a difference which spark plugs to use. Perhaps spark plugs with three electrodes will work longer.
well i still do prefer single electrode sparkplug,
because no matter how many electrode there is spark always just happen once in every trigger, no such thing as having more spark in one cycle,
the only benefit i saw in multi electrode is,. longetivity,
more electrode to eat up means longer time to perform,
but in performance i choose single electrode for the sparks mentain the certain point of location in whiche the burning of mixture happens and it is baoance as to it being at the middle and consistently at the middle always
Super intéressant ,et j'ai vu un testeur de bougies 👍👍👍
Thanks for watching !
What good plug for honda civic ek3 1999
Ngk iridium
Best pluge 1&2&3&4 plz reply
I've found the best plug is the bosch twin electrode plug... just like aviation plugs. Easily 100,000 miles. GMC 350 V-8.
Double spark! Yea dude, totally! 🤯
It's the path ,terminals closer work more than far ones but I understand it's out the box testing
best alloy durability iridium-platinum or iridium-iridium at cathode and anode. fine tip for strong spark power.
Where is the 'multi electrode'? I see only one electrode in the center of all four spark plugs.
How many tune up tools ?
You forgot to mention that the multi electrode plugs can't be gapped. Might be ok on newer engines, but it is critical on older ignotion systems for the longevity of the coil, points, and condenser. Too much gap will cause shorter part life because of the extra energy needed to jump a longer gap.
They will literally work the same when the spark only occur once even with multiple feet. I was just curious about how multi electrodes with multiple feet works
My ex boss had a Hemi Stock Eliminator race car and tested spark plugs on the Dyno. The multi. electrode plugs made 0 h.p. more than the single electrode plugs he was already running. If you have a efficient firing system the amount of electrodes does'nt matter!
5:00 E3 sparkplugs felt noticeably stronger than NGK Iridium
Same here in my 2000 chevy silverado 4.8 the E3 had better take off and the idle had a noticeable difference it was alot smoother then any other plugs I've used in the truck
My bike stops if clutch is not applied properly, then I have to kick start again but earlier it wasn't the problem. What's the problem?
I have never worked on a bike so I can't help you, sorry

Hello !
I have lexus rx450h awd gyl16 2010 runs 116000 km.
I am using 01 pin spark plug genuine company recommended.
Can I use 04 or 03 pin spark plug for good average now is giving 10.5 km per litre in city.
How to increase my average ?
Pls suggest me and thanks
I don't think multiple electrodes are going to make any difference at all.. maybe if you had two spark plugs for one cylinder that would make a difference..
Which one is better for my Polo 2006 1.4 petrol?
