I worked in a Honda dealer in the service department in the early to mid 90's. At that time those multi electrode spark plugs were becoming popular. I remember a customer coming in with his brand new civic. This was a 93 I believe. He complained of a rough idle and wanted it fixed under warranty. But what the technician found was the customer had replaced the spark plugs to those dual electrode plugs. All we did was put the factory plug back in sure enough the engine ran smooth as it should.
That's with most 'after market' stuff. The manufacturer doesn't put wrong parts in your car. Different (colored) spark plug wiring, other size tires, spoilers; it may look nice, but it usually doesn't enhance the ride. Unless you do things with your car that it wasn't really intended for. For the general owner; keep it standard.
Was / is a scam. On Dyno no improvement. A gimmick split fire also. ND had U groove plugs in 1970s did ignite lean mixture better in Japanese motors. NGK best I find. Beware of counterfeit NGK plugs.
E3 Spark Plugs must be a Gimmick then😂Champion has Aviation plugs with either 2 Massive ground straps & Massive Copper electrode or the more expensive Fine Wire 2 Strap & Fine elecrode. I don't remember if they're Platinum but definitely more expensive & longer lasting. Both types seem to run just fine✌🏼😎☯️

As the video points out, the bigger the gap in the plug, the more voltage is needed to jump it... This means that leaving the spark plugs in too long can cause the electrical insulation in the coil to break down and cause the coil to fail. When the power to the 'primary coil' is interrupted the magnetic energy in the iron core collapses and is transferred to the 'secondary coil' and the voltage in the secondary coil will keep rising until it is relieved by the spark happening, if the gap is too large the voltage can reach extreme levels. The use of Iridium and platinum is to massively reduce the 'spark erosion' that causes gap wear, so this allows plug gap to stay in specification for a lot longer. Many coil failures are caused by the plug gap being allowed to get too large
I have had NGK iridium plugs in my 2002 Rav4 and have had zero problems over the last 7 years whatsoever! If you have a new car the NGK iridium are highly recommended as these spark plugs will last at least 15 ~ 20 years! When I removed the NGK plugs after 7 years the plugs were a little brown in colour but looked almost close to new!
You are 100% correct - new cars are not very DIY friendly - the modern car has become a complex piece of machinery. At 13:26 this is a glow plug. For those that don't know - Diesel cars do NOT have any spark plugs.
Modern cars are complex piece of machinery !? How ? Have you even looked at some of the more complex military vehicles? Car computers have little to do, so usually, the auto makers use 3rd or 4 th tier computers for their applications, never leading edge, that will be a waste of computer power, save them for other more demanding uses. Gradually, since 3 decades ago, engineers started assigning more tasks to the computer, such as alternator regulating, cruise control, radar collision, monitoring etc. How the military handle the complexity, they don't, not when you getting shot at. If there is a significant problem with a tank engine or airplane hydraulics, they crane the whole engine out and replace it with another one, called power pack. Or hydraulic pump, The whole power pack take just an hour to change. Then the old one get sent to the rear with the $million dollar equipment and technician to fix.
Thanks- in spite of being a mechanical engineer with 60 years of building engines; I learned a few things from your video. Note that pre-WW 2 piston aircraft engines used multiple spark plug grounds for their magneto-fired engines apparently for more reliability, so this is not quite a new innovation. Racers also found it's also close to impossible to re-gap such plugs without damaging or breaking the center electrode.
The information about Hot and Cold plugs were good... I do find that colder plugs in a hotter plug specified engine such as those that have fuel/air mixtures on the leaner side such as Chrysler Lean Burn tuning, seem to give a smoother running engine and don't foul so long as you don't go too much colder. Ford also has a new sparkplug in the later Ecoboost engines that have a copper crush washer and when tightened to the specified torque, they will all be properly indexed the same way due to the threads in the cylinder head and threads on the plugs being in certain alignments causing the plug to always align in a specified manner to encourage a more complete burn.
Has anyone noticed that modern equipment have become less simpler but more complex. There are creating an ecosystem where you keep needing their services and keep paying them rather than doing it yourself. The concept is profit driven. Once you make a simple machine very complex the more money you can make from sales and repairs.
That's a very cynical take on the situation. The main thing driving complexity is government regulations. Politicians have absolutely no idea how things are done when developing a machine as complex as a car, so they blithely make requirements and mandates which drives (no pun intended) this complexity. The fact that it's bad for the consumer is left as a problem for later politicians.
Actually in the case of engines, it is about meeting fuel economy numbers due to both government mandates, and consumer demand, for those majorities of customers who only understand a bigger number without the detractions to get there, or it's save money now, pay later since new car buyers tend to be better off financially and can just sell or trade in the vehicle before they have to deal with more expensive repairs.

a friend and coworker of mine was a real car guy and would drag race his street 95 camaro. one of the things he did for a bit of a boost was to index the plugs with shim washers to have the electrode pointed right at the intake valve. he also reversed flowed the heads and altered the chip for the throttle body and the thing was really fast and quick.
In many published dynamometer runs since the early 2000’s both car and bike magazines have shown that multiple ground-electrode plugs cause engines to lose 2-3 h.p. at the medium to high rev ranges. Additionally, the 60K to 80K volt ignition coils on modern engines allow the plugs to maintain efficiency to at least 60K miles and in some cases 100K miles.
I own a 2004 Ram Hemi. It has 310,000 miles. Original spark plugs, coils, a/c components. Original ball joints. All engine and trans, rear axle, and diff. Are all original. I changed front shafts once.
In case you didn't know unless you are an aircraft mechanic, the spark plugs with 4 electrodes is called and igniter. They are used in aircraft engines because of the obvious redundancy. Just in case.
Aircraft engines of yester years get their redundancy by having 2 plugs per cylinder. You look at an aircraft engine like the Lycasaurus in a 172 and you think the systems came from the Jay Leno garage.Modern Rotax just use regular single car plugs and features like no lock wires on the oil filter. Literally billions of automotive hours proven that oil filters just do not come unscrewed on their own. Aircraft plugs are maintenance intensive and heavy. Especially using leaded gas.
@@tonylam9548I'm surprised there hasn't been a bigger push for unleaded gas in the aviation industry. I get the issue of valve recession and detonation, but that can be solved in your next engine overhaul and tuning.

@@parkerbohnn If you mean what I think you mean, you won't be able to get them out if you do that. If your engine is losing compression, it means you have to either do a valve job or a ring job. Maybe both.

The Stock spark plug that came with the vehicle is way better than those aftermarket spark plug that failed prematurely. Best bang for the buck would be the original parts.
Agreed! If your car was sold with copper spark plugs when it was brand new, then that means the engine was designed with copper spark plugs in mind; in that case it is best to stay with copper spark plugs, and the more expensive, newer aftermarket plugs will not work as well.
Not always. Sometimes manufacturers make mistakes. I have a c4 Corvette with the lt1 engine. Factory spark plugs were garbage. They were intended to last 50k miles; however, the platinum pucks are known to just fall right off. I changed the factory plugs with 40k miles on them and the majority of those pucks were gone, leaving a plug gap 0.015" wider than those with the puck still present, and way out of factory spec. The plugs were also hotter plugs than necessary presumably for emissions. I moved to a different plug 1 step colder than factory with pucks that won't just fall off at random, and it ran so much better.
@@julshg Even using a good OEM brand of spark plug (and expensive iridium), my 2000 Jaguar XK8 ran worse with those plugs; I ended up going back to the kind of plugs that its ignition system was designed with, then it ran great again. Moral: sometimes the best spark plugs are the kind the engine was designed with.
Accurate and awesome tutorial significantly covering all areas on spark plug subject. Thanks a lot for the easy, understandable professional coaching ❤
Multi-electode plugs were a thing in the early teens, (20th century), until everyone realized that more fire for the firing surface gave better results than more surfaces for the fire.
Or even better, to have neither, to just have same amount of fire so you aren't putting a strain on the ignition coils. Larger gap needs higher voltage. Granted some coils and plugs are easier to get to, and less expensive than others.
@@BlueLinkCams-u8s Shades of my youth. 10,000 miles max. I have trouble believing a 13,000 mile replacement necessary with today's unleaded gas and electronic ignition. They don't care what the vehicle model is. I have over 200K on my original iridium AC plugs. Still good as gold.
This video was not written by an engineer. Most of the terminology was wrong, the different metals are only chosen because of their melting point, hardness and heat transferring properties. Electric conductivity has nothing to do with it. Infact some parasitic resistance is desired because it reduces the current trough the ark and this results in a longer, more stable spark, in less radio interference and less strain on the coil pack and it's electronics. Resistor spark plugs are very common these days, but the parasitic resistance can also be in the cables or in the plug connector. 5 Kohms is the most common value.
It all depends on the shape of your combustion chamber including the type of piston. Absolutely do not never use E-V spark plugs. And not all brands work the same on certain engines.
A bit behind the times now. I have Ruthenium plugs in my car but these weren't mentioned. They have been around for several years now but are rarely mentioned. One of the claims for them is even longer life than Iridium.
beautiful video; thank you. I once had a 2005 Durango with 5.7 hemi; took it to dealership to service the A/C. they found out that I had 100k kilometers and still running the original spark plugs. there was no problem at all. so changing spark plugs every 20,000 miles? not so sure..
Once upon a time, pre mandated unleaded fuel, only Amaco premium gas was lead free with an octane rating of over 100. With leaded gas, 10,000 miles was about the limit before needing replacement...along with the points and setting of point "dwell" and ignition timing. Spark plugs are cheaper now than they ever have been, not even counting inflation. Iridium plugs are da bomb. I've got over 200K on a set and they are just fine. Check once in a while, never a reason to replace, especially since a few require some effort to R & R.
"Changing spark plugs remain accessible and easy to understand" Obviously this video were made by engineers with minimal filed practical experiences. Even back in the 1970s The Chevy Monza V8, the rear most plug at the passenger side require you to loosen the engine mount and jack up the engine to get at it. Many mechanic on flat rate just ignored that plug. Chrysler 400/440 engines, the plugs are under the hot? exhaust manifold where you cannot see, same as some Chevys, Ford Mustang 390 , there is about one inch of space to work with between the engine and spring tower. More recent, some of the Toyota V 6s require you to remove the wiper motor, and linkages, the sheet metal body structure below the windshield (better be careful you do not ding the windshield) the throttle body and intake manifold to get at the rear 3 plugs. You forgotten to tell us what you been smoking before you made this video.
I remember the Chevy Monza with that inaccessible spark plug, but some Toyotas require all that just to remove plugs? And people still think they are "wonderful"? Glad I don't have one!
I've only seen multi-anode sparkplugs used in aircraft engines, and they run dual sparkplugs & magnetos. For cars & motorcycles, I've had good luck with ND Hot-U and iridium split anode sparkplugs .. get slightly better fuel economy, engine feels a bit peppier and cold starts seem quicker
I had a motorcycle that used what was called a surface gap plug. It looked very much like they had taken a conventional spark plug and cut off the protruding electrode. It was in a two stroke motorcycle that had some serious problems with spark plug fouling. It really did not help in any way, the primitive (1972) electronic ignition was not as good as a similar era conventional ignition
I find that E3 spark plugs are the best in my opinion. I have numerous muscle cars and these are the only plugs I use. I even put these in my motorcycles, ATV's and my zero-turn mower.
Very good session I always wonder how this item works I don't absorb ever thing but I learnt some thing thank u and I will review it again and make some notes so I can revise it accasionally
Nope, you Bozos. There are multiple paths sometimes - finest example is a lightning strike (it often contains a "leader" and small "streamers", not visible - if someone survives a strike, it was a streamer, not main channel).
@@syrsknight "Path of least resistance" is a simplification, a fairytale for children. In high voltages it's about the EM fields (gradient of the field, electrodes shape, chemical composition of the mixture in the cylinder).
One very expensive repair is when an engine invests water and hydro-locks, bending connection rods and ruining the motor. Adding a pressure-release valve would be difficult to retrofit, and probably require a redesign of the cylinder head, but what if the spark-plug was designed to be this pressure release valve? Then you could retro-fit any gas-engine. Boat motors are the obvious application, but I feel the military would be very interested in accelerating the recovery time of a submerged vehicle. Off-road vehicles, and motorcycles would benefit. As this video mentions, replacing the spark plugs is one of the last things a casual owner can replace. I would think the insulator would provide a route to making this idea work.
A solution looking for a problem. Far easier to just not let water get in the engine and if it gets flooded or something, pull the plugs before trying to start it.
Fifty years ago installing a extra high voltage spark coil was a pretty common modification. It was also a very simple mod as it was just a drop in replacement unless your spark wires were just bad. It didn't really do much difference in most cases but it could help people pump a bit more power out of their engines as they used sparkplugs with a wider gap. Never bothered to do it myself as I wasn't interested. But it was just one of those things they tried to sell you.
The american factory "Pulstar" made amazing brand spark plugs ! In particular on 2 stroke engines and carb or first gen of injection system on cars or motorcycles... There's a capacitor include inside the spark plug.
champion plugs use an air gap as capacitance For some reason my old Jaguar straight six only liked champion plugs. I favored a Japanese brand , but there was no arguing with results.
My 2004 Hemi has 16. Has 310,000 miles with original spark plugs. In fact, every engine and transmission part is original. No check engine light, no smoke, no ticks or knocks.
I like iridium spark plugs ,they can run up to 100,000 before you might have to replace them.they are already pre-gapped,so you don’t need to gap them.
I run stock plugs on my GTI with 200 hp more than stock. Not even 1 step colder. I change them every 15,000 miles ans ive had no issues. With hybrid turbos at 500+ bhp most guys run recessed tip plugs where the ground strap is flat and protrudes diagonally up from the body of the plug. They are like $40 each last i checked lol.
Aircraft engines have 2 sparkplugs per cylinder and one is supplied electric power from oen magnito not a coil and the remaining plugs are supplied by a second Magnetio. All this for reduncy.
"Cold" or "hot" is extremely important to the lifespan and ignition quality (how the engine runs). I have an old Evinrude outboard (1970) originally built for leaded fuel. Now I run unleaded in my mix (50:1). The original spark plugs or equivalent run too cold and end up with black residue pretty quickly. I changed for a "hotter" spark plug and the problem is gone.
Awesome TEP《☆》👍🏾🍔🤳I'm looking for the best Plugs to give long Life & Best Performance in my 5.7L HEMI. I bought the 2014 Charger Pursuit with 117k miles on it. No maintenance records were provided.

if one enjoys talking about spark plugs, live it up. but they only trigger the ignition event , then their work is done. there is only one ignition event. they do not increase power, they only trigger the ignition vent.
Iridium spark plug do last a lot longer and less prone to premature failure. My 2013 camry has 126k miles on the clock with the original spark plug that came with the car. Thats how durable those iridium spark plugs are.
Had no luck with split fire plugs in my car, but E-3 plugs last far, far longer in my riding lawn mower that burns a little oil than single electrode plugs.

If chances added up to establish more than one ionization pathways simultaneously, there will be benefit in multiple electrode plug. The reality is when the first one ionization path is completed, this path will draw current and the ignition coil high voltage output will drop very quickly so that the potential second path will not get enough voltage to develop further.
If you ever go to start your car and it cranks but kinda struggles then starts it’s usually worn spark plugs. Also it can effect fuel have you ever gone to the gas station filled up and then after a few days your almost at half a tank empty. All signs it’s time to change the spark plugs.

@@BlueLinkCams-u8s Shades of my youth. 10,000 miles max. I have trouble believing a 13,000 mile replacement necessary with today's unleaded gas and electronic ignition. They don't care what the vehicle model is. I have over 200K on my original iridium AC plugs. Still good as gold.
With courage you will dare to take risks, have the strength to be compassionate, and the wisdom to be humble. Courage is the foundation of integrity.
The right spark plug is the one the manufacturer says is the right one !
This was actually well made :)
It's completely AI generated.
This video was not written by an engineer. Most of the terminology was wrong, the different metals are only chosen because of their melting point, hardness and heat transferring properties. Electric conductivity has nothing to do with it. Infact some parasitic resistance is desired because it reduces the current trough the ark and this results in a longer, more stable spark, in less radio interference and less strain on the coil pack and it's electronics. Resistor spark plugs are very common these days, but the parasitic resistance can also be in the cables or in the plug connector. 5 Kohms is the most common value.
At 10:20 , what’s with the blunts 😂
At 10:14, but yeah, lol
It all depends on the shape of your combustion chamber including the type of piston. Absolutely do not never use
E-V spark plugs. And not all brands work the same on certain engines.
A bit behind the times now. I have Ruthenium plugs in my car but these weren't mentioned. They have been around for several years now but are rarely mentioned. One of the claims for them is even longer life than Iridium.
beautiful video; thank you. I once had a 2005 Durango with 5.7 hemi; took it to dealership to service the A/C. they found out that I had 100k kilometers and still running the original spark plugs. there was no problem at all. so changing spark plugs every 20,000 miles? not so sure..
Once upon a time, pre mandated unleaded fuel, only Amaco premium gas was lead free with an octane rating of over 100. With leaded gas, 10,000 miles was about the limit before needing replacement...along with the points and setting of point "dwell" and ignition timing.
Spark plugs are cheaper now than they ever have been, not even counting inflation. Iridium plugs are da bomb. I've got over 200K on a set and they are just fine. Check once in a while, never a reason to replace, especially since a few require some effort to R & R.
05 crv. Original iridium plugs. Pulled@150000, neverseized threads & reinstalled; still running well@284000; gas mileage, power same as always😁

"Changing spark plugs remain accessible and easy to understand" Obviously this video were made by engineers with minimal filed practical experiences. Even back in the 1970s The Chevy Monza V8, the rear most plug at the passenger side require you to loosen the engine mount and jack up the engine to get at it. Many mechanic on flat rate just ignored that plug. Chrysler 400/440 engines, the plugs are under the hot? exhaust manifold where you cannot see, same as some Chevys, Ford Mustang 390 , there is about one inch of space to work with between the engine and spring tower. More recent, some of the Toyota V 6s require you to remove the wiper motor, and linkages, the sheet metal body structure below the windshield (better be careful you do not ding the windshield) the throttle body and intake manifold to get at the rear 3 plugs. You forgotten to tell us what you been smoking before you made this video.
I remember the Chevy Monza with that inaccessible spark plug, but some Toyotas require all that just to remove plugs? And people still think they are "wonderful"? Glad I don't have one!
Excellent explenatoin and video 👌
Answers so many questions. Thank You...!!!
I've only seen multi-anode sparkplugs used in aircraft engines, and they run dual sparkplugs & magnetos.
For cars & motorcycles, I've had good luck with ND Hot-U and iridium split anode sparkplugs .. get slightly better fuel economy, engine feels a bit peppier and cold starts seem quicker
I had a motorcycle that used what was called a surface gap plug. It looked very much like they had taken a conventional spark plug and cut off the protruding electrode. It was in a two stroke motorcycle that had some serious problems with spark plug fouling. It really did not help in any way, the primitive (1972) electronic ignition was not as good as a similar era conventional ignition
Mercury outboards had surface gap plugs.
I find that E3 spark plugs are the best in my opinion. I have numerous muscle cars and these are the only plugs I use. I even put these in my motorcycles, ATV's and my zero-turn mower.
In the older days on the 1980's they were called splitfire spark plugs.
Very good session I always wonder how this item works I don't absorb ever thing but I learnt some thing thank u and I will review it again and make some notes so I can revise it accasionally
Amazing video 😍
Surface discharge for the win ..... Well have had rotary bikes, so that's where the love comes from 😎
Glad u put the disclaimer 😂😂😂was looking for expert advice…none here…lol😂🎉🎉🎉
Thank you. A real lesson about spark plug and mithbuster also.
This is high school level science. To complete its circuit, electricity takes ONE single path (not multiple paths) of least resistance to ground.
It takes the path of leadt resistance
Correct. Multiple paths mean less intensity.
Nope, you Bozos. There are multiple paths sometimes - finest example is a lightning strike (it often contains a "leader" and small "streamers", not visible - if someone survives a strike, it was a streamer, not main channel).
@@syrsknight "Path of least resistance" is a simplification, a fairytale for children.
In high voltages it's about the EM fields (gradient of the field, electrodes shape, chemical composition of the mixture in the cylinder).
One very expensive repair is when an engine invests water and hydro-locks, bending connection rods and ruining the motor. Adding a pressure-release valve would be difficult to retrofit, and probably require a redesign of the cylinder head, but what if the spark-plug was designed to be this pressure release valve? Then you could retro-fit any gas-engine. Boat motors are the obvious application, but I feel the military would be very interested in accelerating the recovery time of a submerged vehicle. Off-road vehicles, and motorcycles would benefit. As this video mentions, replacing the spark plugs is one of the last things a casual owner can replace. I would think the insulator would provide a route to making this idea work.
A solution looking for a problem. Far easier to just not let water get in the engine and if it gets flooded or something, pull the plugs before trying to start it.
1:16 I think that's part making me laugh😅.
😂same.
Very helpful presentation! Great narration and excellent visuals!
Fifty years ago installing a extra high voltage spark coil was a pretty common modification. It was also a very simple mod as it was just a drop in replacement unless your spark wires were just bad. It didn't really do much difference in most cases but it could help people pump a bit more power out of their engines as they used sparkplugs with a wider gap. Never bothered to do it myself as I wasn't interested. But it was just one of those things they tried to sell you.
I ALSO recommend Engineer type also look at Torquemaster S plugs. AS long as you put 60k volts to it , nothing else pulls like it.
The american factory "Pulstar" made amazing brand spark plugs ! In particular on 2 stroke engines and carb or first gen of injection system on cars or motorcycles... There's a capacitor include inside the spark plug.
champion plugs use an air gap as capacitance For some reason my old Jaguar straight six only liked champion plugs. I favored a Japanese brand , but there was no arguing with results.
My question was answered at the very end but glad I watched the whole thing!
A finest video on all spark plugs
My 2004 Hemi has 16.
Has 310,000 miles with original spark plugs.
In fact, every engine and transmission part is original.
No check engine light, no smoke, no ticks or knocks.
Exactly. Iridium plugs easily last 160,000+ kms. Changing plugs every 20k’s is a complete waste of time and money
YOUR FULL OF SHYT. NO WAY THAT HEMI LASTED YOU THAT LONG WITHOUT THE TIMIMG CHAIN TENSIONERS FALLING APART!!!
Replaces fuels pump power steering rack, axles and maintenance parts
@@chutasan8299exactly…hemis love eating cam lobes and rotting exhaust manifold hardware.
This is a great video. There is information that I never knew. Thank you for sharing.
THANK Y BUT THE HONEST AND TRUE FOR THE ORIGINAL SPARE PARTS IN THE 80 BY MEAD IN JAPAN THAT WE MISS
Very educational, than you, watched from Old Harbour Jamaica.
Well done, now I'll kn9w why the gaps and better select my future plugs😊
I like iridium spark plugs ,they can run up to 100,000 before you might have to replace them.they are already pre-gapped,so you don’t need to gap them.
I run stock plugs on my GTI with 200 hp more than stock. Not even 1 step colder. I change them every 15,000 miles ans ive had no issues. With hybrid turbos at 500+ bhp most guys run recessed tip plugs where the ground strap is flat and protrudes diagonally up from the body of the plug. They are like $40 each last i checked lol.
Awesome coverage of information!
Very helpful and educational. God bless you. I love this
4 electrode is used in sports car
Not all of them
Very informative. Especially surrounding the myths that salesman and mechanics alike believe to be true.
Good bit if knowledge.... Was wondering why the 2 blunts by the 1974 pic😏🔥🔥
Maybe you should explain NGK Iridium racing spark plug, not anyone of these above... ;-)
I learned a lot in just this one video 💯
Did he say that new spark plugs are good for 18000 miles? Mine are good for 105000 miles according to the owners manual. Still a very nice video.
I drove a 1988 Nissan pintara 4 cylinder which had 2 spark plugs per cylinder. Advantages/disadvantages could be mentioned.
Thank you for this fantastic video!keep going! A strong thumbs up from Dingfeng Precious Metals Recycling!
Excellent explanation thanks
Entre para ver wue bujias eran mejor y termine tomando una clase de historia, que buen video.
Aircraft engines have 2 sparkplugs per cylinder and one is supplied electric power from oen magnito not a coil and the remaining plugs are supplied by a second Magnetio. All this for reduncy.
If you have multiple ground plug you need more voltage, better coil or MSD ignition.
Was quite informative and interesting--Thanks.
"Cold" or "hot" is extremely important to the lifespan and ignition quality (how the engine runs). I have an old Evinrude outboard (1970) originally built for leaded fuel. Now I run unleaded in my mix (50:1). The original spark plugs or equivalent run too cold and end up with black residue pretty quickly.
I changed for a "hotter" spark plug and the problem is gone.
What is ruthenium spark plug ? Better than iridium?
i used 2 use split fire plugs they would give better fuel milage than conventianal ones
Awesome TEP《☆》👍🏾🍔🤳I'm looking for the best Plugs to give long Life & Best Performance in my 5.7L HEMI. I bought the 2014 Charger Pursuit with 117k miles on it. No maintenance records were provided. I'll pull one of the Spark plugs out & see What's in it. I've heard the Bosh Double Iridium are the best HEMI plugs but I'm thinking Double Platinum should be fine for a higher mileage car. What do You suggest for my 5.7L HEMI??✌🏼😎☯️
Life is what you make of it. Always has been, always will be.
if one enjoys talking about spark plugs, live it up. but they only trigger the ignition event , then their work is done. there is only one ignition event. they do not increase power, they only trigger the ignition vent.
Great information, thanks ❤
Very well made video ✅ thanks !
Excellent video!
Iridium spark plug do last a lot longer and less prone to premature failure. My 2013 camry has 126k miles on the clock with the original spark plug that came with the car. Thats how durable those iridium spark plugs are.
Very informative ,thanks a lot.
Very good information
Had no luck with split fire plugs in my car, but E-3 plugs last far, far longer in my riding lawn mower that burns a little oil than single electrode plugs.
I'm using e3 diamond spark plugs in my SLT V8 magnum 5.7l engine dodge Durango I really love using them
Iridium sp adds some horsepowers
especialy at low rpms
and it gives extra fuel economy
Iridiums are meant for durability due to less voltage being required to fire
No plugs give you more HP. Only better fuel economy
@@shadowopsairman1583 so spark is better and burning gives more power
@@hamiltoncouple01 iridium plugs do more hp
Spark plugs should be connected to wires, unless you have wireless ones.
The one that is recommended by the manufacturer. 😊
Very helpful

the best spark plug was the (super bosna) made in jugoslavija
How about the Pulstar Spark Plugs?
I don't see any benefits of a multi electrode plug. Electricity flows in one direction. Not several.
Exactly. It’s going to jump to whichever one is closest to the electrode
If chances added up to establish more than one ionization pathways simultaneously, there will be benefit in multiple electrode plug. The reality is when the first one ionization path is completed, this path will draw current and the ignition coil high voltage output will drop very quickly so that the potential second path will not get enough voltage to develop further.
I have a 2000 Volkswagen Passat with a 1.8 t engine. I have run Bosch plus fours in this since I have owned it. It doesn't run well on anything else!
*_I learned more here than I do in my math class…_*
Excellent 👍👍
If you ever go to start your car and it cranks but kinda struggles then starts it’s usually worn spark plugs. Also it can effect fuel have you ever gone to the gas station filled up and then after a few days your almost at half a tank empty. All signs it’s time to change the spark plugs.
