Anyone who owns an 86-91 Mercedes 420 or 560 SEC/SEL will appreciate this hack since the original OEM factory plugs by Bosch were non-resistor but are no longer manufactured and trying to use resistor plugs makes the engine run like crap. Thank you for a quick solution to a long standing problem!
I know I should try & look up yiur Mercedes engind, but what ignition system & coil does it use & injection system? They always said the RFI/EMI would disrupt the computer & radio. I wonder if it can do the same for GPS, & cell signal???
Thank you, modified (4) Champion RN12YC yesterday for Massey Ferguson 135. Checked ohms on all 4 beforehand 3 @ 65k ohm 1 @ 1.3 M ohm on new plugs. Made all 4 to be 0.3 ohms.
Ive got a spare brand new set of Denso u-groove plugs for my ecotec v6 3.8 litre buick based engine in Australia. I got to do this. Top video. Subbed and liked 👍
If its equipped with a resistor plug you need it. Electronic ignitions dont like electromagnetic interference and non resistor plugs wont last long with low ohm coils
Hi.....why won't the non-resistor plugs last long with low ohm coils? How low is low? Like GM HEI potted coils or MSD HVC II Coil? Primary or Secondary side resistance?
Great idea. I have been trying to find the non-resistant version of the spark plugs I use and no auto store carries them. So I used your idea. Since I did not have the wire size to match the size of the resistor I just used 3 14 gauge solid wire and they fit just right in the spot the resistor sat. Since the plugs I was using were in great shape this saved me money as well. Also I did not need to torch the plug to loosen the tip. Just use a good old socket and pliers and it came loose.
A great tip. My Ryobi 2stroke motor was a pig to start. Weak spark was shown, cleaning and resetting ignition module made no improvement, but taking out the 9k resistor and the spark doubled in size. Good starting achieved at last. ( All other you tube videos concentrate on carb problems with these engines. The weak spark from a flywheel magneto is hardly mentioned)
Why the fuck would you buy a resistor plug for a weed wacker? Magneto ignitions have high ohm coils and a resistor plug will give a weak spark. Resistor plugs are for high energy digital ignitions. Go cheap non resistor plugs and dont expect any life out of 120 volt wire when you pass 20 to 30 thousand volts through it.
Very useful video, and Interesting comments. I think there is a proper place for this, many useful references where you can look up the reduction of actusl spark energy with resistor plugs. I have built and tested more than100 coil and ignition arrangements to actually establish the heat energy transfered to the gas, and not just voltage. Lean mixtures require more voltage as there are lower levels of ionised fuel air molecules crammed into the same space. Modern ecu's are more prone to Electromagnetic (EM) interference, and hence agree this mod may well upset it, but there are ways of mitigating it. In my application running an old OE Renix ecu, single coil, and distributor on a V6 forced induction application, I find as I increased the boost and mass flow through the engine (doubled the power from the OE spec), I had real issues with spark mis-fire. The OE plugs were originally non-resistive that are now NLA, with the replacements as resistor suppressed items. I did some back-to-back testing on a dyno, and had significantly more issue with the resistor plugs and increased boost - I was controlling the plug gap, prep, and fuelling. I then launched into the investigation of the coils, inductance, turns ratio etc, to see if I could improve the situation , and get to the boost levels I wanted to go. I did loads of testing, and the boost pressure I could reach followed linearly in terms of net % increase with the spark energy available, so I kept tracking the issue up with revised coil arrangements. But the underlying point was I needed all I could squeeze out of the system ( keeping the Renix ecu than going after market), and non-resistor plugs were a key element of pushing this arrangement to higher performance for my application. As the OE non-resistive are NLA, I will be making this modification to the resistor suppressed replacements. So I am grateful to this video, increasingy my knowledge base, and giving me more options. Cheers.
M Faulks great comments, glade you took time and write it. I was and am aging spark plug resistor. It really gets hard to buy no resistor plugs these days
Good video to have in my toolbox. Looking for non R plugs for my classic Mercedes, difficult to find and expensive to purchase(12.00 each) They are just not available as they used to be.
In a standard/factory ignition system if you remove the resistance between the spark plug and the coil you stifle the operation of the ignition coil output by effectively shorting out the high voltage side of the coil. This short prevents the magnetic field in the coil from collapsing quickly limiting the output voltage of the coil. Unless you have a coil designed to operate under these conditions I think the only gain you would get is a bunch of EMI that will be generated from the system.
I found this info on another site: NGK strongly recommends using resistor spark plugs in any vehicle that uses on-board computer systems to monitor or control engine performance. This is because resistor spark plugs reduce electromagnetic interference with on-board electronics. They are also recommended on any vehicle that has other on-board electronic systems such as engine-management computers, two-way radios, GPS systems, depth finders or whenever recommended by the manufacturer.
SubvenioArguo yup the spark goes to ground so does EVERYTHING else. The resistor is accounted for in the coils. match plug, wire, coil, computer and vehicle together or be sorry.
I wondered about this & why a person couldn't buy special EMI/RFI wraps & insulate from the plugs porcelain, plug wires, & wrap the entire distributor cap......?
good to know... I question some peoples choice of non-r plugs but there are certainly instances where it will make a difference (albeit just a tiny difference)
They won't fry your ECU. The ECU only sends a signal to the ignition module that powers the coil. The ONLY thing you can even potentially damage is the coil itself from the extra current, which isn't likely. If you have direct ignition coils, the principles are the same. The ECU only sends a signal, not actual power.
Attention ! I tried this modification with a NGK Iridium spark plug and the construction isn't the same as the Champion plug shown in the video. There's no spring and separate resistor inside the ceramic housing, just a solid shaft that incorporates the resistor, and this gets broken if dismantled as suggested. Unfortunately the modification won't work for this type of plug.
No, on some Champions the top connector will not unscrew and it's a one piece design and will snap off if you try and unscrew it. You might have to test several different ones to find the type that unscrews.
I think they did it so it can distributed the Power evenly. Some Spark Plug Wires are " LONGER " than the others... Only way to get Electricity to flow evenly to " ALL " of your Plugs is put in a Resistor. In reality you don't need them, but because Power must distributed evenly, they put the Resistors in them. You can definitely do this to your Lawn Mowers since they have ONE Spark Plug :)))). NOTE: Sometimes, some Spark Plugs are " WEAKER " than Others (Due to Corrosion, Wear and Tear, Carbon, Etc... ), having the Resistor will help since Power is limited by a Resistor so the Other's won't "OVER " Power the Weak ones.
It seems there are idiots in this world who show their lack of knowledge by throwing about non-tenable theories about power distribution. If those same idiots would take the trouble to read the publications and catalogs of the spark plug manufacturers, they could learn that the sole purpose of the resistor in the spark plug is the suppression of RFI, i.e. Radio Frequency Interference, which would interfere with radio- and television reception, mobile phones and (on-board) computer systems and other electronic systems. No word is said by those manufacturers about even "power distribution", which makes no sense anyway. It is also typical of said idiots that, if someone questions them on their non-tenable theories, they do not react with reason and answer questions, but immediately start calling people "dam stupid" or "fucking stupid". And trying to confuse the issue by inventing non- existing grammar mistakes in his opponents comments. Ah well, I presume it takes all kinds.
I wondered about this & why a person couldn't buy special EMI/RFI wraps & insulate from the plugs porcelain, plug wires, & wrap the entire distributor cap......?
What he showed you was a ZERO ohm spark plug The key difference being the "Non resistor" plugs although while having no ADDED resistor still tend to have small amounts of resistance.. so his zero ohm plug isn't the same thing one can buy cheaper.
It's great for the engine. It may not be great for various ECUs, CDIs, radios, etc. if there isn't adequite RFI shielding. It's great for the engine, though.
What brands of plugs besides Champion does this work on? I know it doesn't work on NGK plugs as the threads on the center post are much further down inside and the center post will twist in half before the threads come loose. I've got a 2-stroke engine that could benefit from non-resistor plugs but finding a plug with the right specs in a non-resistor version is proving difficult.
in response to tony, just buy the non-resistive plug for your application and learn how to make KML wires for the power boost. im using one of those cheapy 2 cycle kits for the bicycle and found KML wires to be beneficial. unfortunately, because of the primitive engine setup, i cant get it to run right with an expansion chamber :( im sure it will run fine on anything else than cheapy chinese engines ;)
@@James_Bowie more complicated than that. Before plasma formation it is an open circuit. voltage will build up at the tip to the same threshold voltage, regardless the resistor that’s in series. It will limit the current
Don't try this with the newer iridium style plugs. You will ruin an expensive spark plug. Old farm tractors with magneto or points ignition and solid core wires will benefit from non resistor plugs slightly, as these were originally designed as non resistor ignition systems.Easier start up and reduced oil fouling in these old engines.
Interesting, I used to hear that on my old (magneto ignition) motorcycles not to use resistor plug caps, but nobody ever mentioned about resistor plugs, all I recall is if you've a weak spark, leave a gap between lead and cap ? Which some say nackers the mag up, Always thought that dodgy meself Also, I used to love vehicles without resistors as they stuffed up car radios on the vhf (fm) band ! Also nobody's mentioned that nearly all spark plug caps have a 5k ohm resistor in em, hows about that then guys n' gals ?
Get out the blow torch! I also saw that Bosch style rotors also are spec with 5k resistance..... so thats maybe how they did it instead of resistor in caps. MSD & Accel included low resistance carbon buttons for the HEIin coil caps.....🙊🙉🙈
This works great with solid core spark plug wires with a mechanical distributor with points. Spark plug wires are suppression core (resistant) So you won’t get any benefit on efi plug wires. Do not use solid core wires with MSD ignition‘s. Is very dangerous.
Funny my vette has msd and solid core wires and non resistor plugs and plug caps. So I guess after 18 years of running well I was just lucky . Or maybe computer shit and electronic injectors suck . And they need wimpy ass spark so they can work .

Biar pengapian lebih besar kang, tapi gk recommend untuk mobil/motor yg pake ECU soalnya nanti ada interferensi sama chip chip dalem perangkat elektroniknya..
Apparently a non-resistor plug generates enough interference in the 2.4 Gig band, so when the perverts are flying a drone over your house filming your kids or looking for stuff to steal, you can put this in you lawnmower and cause the drone pilot to lose control. I will be testing this theory ASAP.

Why not just use a quality plug like an Autolite non resistor plug? Fuck the multi piece Champion piece of shit! Vick Edelbrock took a 350 horse 327 and dyno' dit to see what it truly made. After a gentle break inperiod it made 313 hp. It had AC plugs in it. The first mod he tried in brings it up to the specified hp was to change brands of plugs. Champions made no difference, it Autolites made 318 hp. That was 60's technology, but even then they were better than Champion. Even Autolite resistor plugs have a solid center electrode! No fucking bullshit spring, not four pice center electrodes. And as for Vick's 327, when he tore down the motor he found almost ever spec Chevy claimed the motor had was off. Instead of 10.5-1 it had 10.25-1 pistons. Every spec was different, so he blueprinted the motor and tried again. It took a few mods to make 350hp, and in the end of his experiment he got the motor to put out something like 440 hp. But Champion plugs were not part of that combination, and shouldn't be in your engine!
New cars don't need resistors because they have digital radios..... never mind the 500 miles of unshielded wire running to the ecu haha. Some peoples kids.
The video show you how to do something. You call it just one of the stupid videos that you have seen on UA-cam. I bet you have left very similar comments on other videos. This might help you to understand what you do not seem to grasp. A video that shows you how to do something does not mean that its the only way. You call it stupid because the video does not help you and if you want plugs like this you would simply go buy them. Thats not stupid. Other people might trying to quickly do this to a plug and they may not be near a store or maybe they dont want to buy plugs because they have these plugs right there in front of them. My point is that you must be really really really stupid because this is just common sense. The real test is are you really stupid or did you just make a stupid comment. The way to know for sure, is if, right now, right this second, you are sitting there all angry, working out the insulting stuff you are going to say to me including my spelling and grammar mistakes (that verifies that you are stupid, plus pointing out grammar as many do kinda shows that WHAT is being said is over your head, but the way it was said is not) OR are you thinking "yeah, I did make a stupid comment" . I would bet it is rare for someone to insult a persons hard work and then come out and just admit that they were wrong or that they are sorry for saying it.) If you are American then it may be impossible to do that anyway;.
That is utter rubish. I have no clue what you're talking about when it comes to 11000 hp engines, and I fail to see the use of spark plugs that last only less than a minute. On my classic racing motorcycles I use two spark plugs, NOT to get better ignition (which it doesn't) but to get short flame fronts which allows the ignition timing to be retarded, and gives because of that ca. 3% more power. For the same reason my four-valve car has 3 spark plugs per cilinder, which makes it more expensive to service. Here, again, the aim is to get shorter flame fronts and to avoid pre-ignition (pinking). All research has indicated that the average spark energy of an old, conventional system with breaker points, is already approx. 40 times the required energy, let alone that of an electronic system! Once the spark, however small, has ignited the mixture, the resulting flame front is so much bigger that the iniating spark is of no consequence.
And that's precisely why I use two spark plugs per cylinder: two burn the stick from both sides. I recommend that you study the research on this. I don't know your education on this matter, but I'm a university graduated mechanical engineer, and have been a successful tuner of racing motorcycles. And herewith I end this conversation.
I think they did it so it can distribute the Power evenly. Since some Spark Plug Wires are " LONGER " than the other... Only way to get Electricity to go evenly to " ALL " of your Plugs is put in a Resistor. In reality, you don't need them, but because Power must distribute evenly, they put the Resistors in them.

That is the MOST STUPID THING I'VE SEEN,in 47 years of doing mechanics!! Just BUY the non-resistor version of the plug. Also,the resistor is there,to suppress interference,and it also affects the heat range ! The loss of any spark in a resistor plug is so small,it's a waste of money,and time! Also the spark plug WIRES have more resistance,than the spark plug !

how do you if the spark plug is non resistor or resistor type?
+Jobert Cadag (Bert) It has a letter there. R- Resistance

untuk apa om busi resistor diubah jadi non resistor?
Biar pengapian lebih besar kang, tapi gk recommend untuk mobil/motor yg pake ECU soalnya nanti ada interferensi sama chip chip dalem perangkat elektroniknya..
Could you tell us what size copper wire you used? Thank you!
From what I see, I think it's 12 Gauge. Or find the Wire that is Thick enough and fit in nicely.
Apparently a non-resistor plug generates enough interference in the 2.4 Gig band, so when the perverts are flying a drone over your house filming your kids or looking for stuff to steal, you can put this in you lawnmower and cause the drone pilot to lose control.
I will be testing this theory ASAP.
magneto ignition systems.
wrenchguy only if non resistor plug cap
😂
É vecchio... Questa modifica la facevo io circa 30 anni fa sulla mia UnoTurbo ie del 91...
Interessante
Damm... i would just have extended that spring,and re-assemble...
Makasih atas Vidio nya
Do you remove the resistor and replace it with a piece of copper wire?
Had no idea there were freaking springs inside spark plugs.
Now you know :)))
Have you ever open a spark plug
Что он сделал для чего???
how can I make a resistorless a resistor plug?
why do they have resistors
I think they did it so it can distribute the Power evenly. Since some
Spark Plug Wires are " LONGER " than the other... Only way to get
Electricity to go evenly to " ALL " of your Plugs is put in a Resistor.
In reality, you don't need them, but because Power must distribute
evenly, they put the Resistors in them. You can definitely do this to
your Lawn Mowers since they have ONE Plug :)))). NOTE: Sometimes some
Spark Plugs are " WEAKER " (Due to corrosion and Carbon, Etc... ),
having the Resistor will help since Power is limited by a Resistor, the
other won't "OVER " Power the Weak ones.
@@JodBronson Distribute power evenly? By putting resistors in? Since all those resistors have the same value, there is still no change in power distribution. Which is a nonsense reasoning anyway!
+Joep Kortekaas - You FUCK HEAD, READ READ READ !!! Learn how *High* Electrical current flows, then come back and talk to me! By the way, I can tell by your so called " Education Level " just from ONE fucking paragraph that you wrote above! A 3rd Grader can write a Sentence better than that! *Try this one.... Forrest Dumb - Nigga is, Niggas does!* 😂😂😂😂😂😂😂😂😂😂😂😂😂
@@JodBronson Fact is, that the current in ignition systems is not high, but actually very low, reason that a shock from the system is rather harmless. And, by the way, what is your education level and experience with engine tuning? I get the impression that you are the one who has no clue about power distribution, but maybe I'm wrong. And please enlighten me about which sentence it was that a third grader could write better, since I've written several sentences. Also, you THINK that they did it to distribute power evenly, well, I think they didn't. No reason to assume you are right and I'm wrong, but maybe you can show how putting resistors in would distribute the power "evenly".
+Joep Kortekaas - Hahahahahaha.... Seriously, you need to go back to 3rd Grade English 101! It's called *Reading Comprehension* for a reason. There are actually 2 words there! Hahahahahahaha... *Try this one.... Forrest Dumb - Nigga is, Niggas does!* 😂😂😂😂😂😂😂😂😂😂😂😂😂
I'm trying to resist buying resistor plugs but if I bought NGK's iridium plugs an made them non resistor will they spark just as well an last long
Longest diagram
dont try to listen to your radio after this
lol imagine still listening to the radio
Tried this on NGK iriduim plug. The interior shaft sheared! It was money wasted as the plug is now broken and useless! 😠
NOW,THROW IT OUT? ; the tip is gonna come off easily; at least,make sure that the wire boot is tight.
Jose Peixoto I simply reheated the top of the plugs and they all sealed again.
Why not just use a quality plug like an Autolite non resistor plug? Fuck the multi piece Champion piece of shit! Vick Edelbrock took a 350 horse 327 and dyno' dit to see what it truly made. After a gentle break inperiod it made 313 hp. It had AC plugs in it. The first mod he tried in brings it up to the specified hp was to change brands of plugs. Champions made no difference, it Autolites made 318 hp. That was 60's technology, but even then they were better than Champion. Even Autolite resistor plugs have a solid center electrode! No fucking bullshit spring, not four pice center electrodes. And as for Vick's 327, when he tore down the motor he found almost ever spec Chevy claimed the motor had was off. Instead of 10.5-1 it had 10.25-1 pistons. Every spec was different, so he blueprinted the motor and tried again. It took a few mods to make 350hp, and in the end of his experiment he got the motor to put out something like 440 hp. But Champion plugs were not part of that combination, and shouldn't be in your engine!
Ngomong opo sih kowe cak 😆😆😆😆
Why fuck around like that just buy non resistor plugs from the auto store
I've seen some stupid shit on UA-cam, and this is one of them.
Just buy the plugs you want.
New cars don't need resistors because they have digital radios..... never mind the 500 miles of unshielded wire running to the ecu haha. Some peoples kids.
Has nothing to do with the radio.....
yellowsupra88 you don't need shielding on twisted data bus wires
+yellowsupra88 digital radios... MORON.
The video show you how to do something. You call it just one of the stupid videos that you have seen on UA-cam. I bet you have left very similar comments on other videos. This might help you to understand what you do not seem to grasp. A video that shows you how to do something does not mean that its the only way. You call it stupid because the video does not help you and if you want plugs like this you would simply go buy them. Thats not stupid. Other people might trying to quickly do this to a plug and they may not be near a store or maybe they dont want to buy plugs because they have these plugs right there in front of them. My point is that you must be really really really stupid because this is just common sense. The real test is are you really stupid or did you just make a stupid comment. The way to know for sure, is if, right now, right this second, you are sitting there all angry, working out the insulting stuff you are going to say to me including my spelling and grammar mistakes (that verifies that you are stupid, plus pointing out grammar as many do kinda shows that WHAT is being said is over your head, but the way it was said is not) OR are you thinking "yeah, I did make a stupid comment" . I would bet it is rare for someone to insult a persons hard work and then come out and just admit that they were wrong or that they are sorry for saying it.) If you are American then it may be impossible to do that anyway;.
not recommended for injection
wow !! that dude's got some hairy arms !!

When will you people ever learn, that the intensity of the spark has absolutely NOTHING to do with efficiencies, power, emissions or fuel consumption!
That is utter rubish. I have no clue what you're talking about when it comes to 11000 hp engines, and I fail to see the use of spark plugs that last only less than a minute. On my classic racing motorcycles I use two spark plugs, NOT to get better ignition (which it doesn't) but to get short flame fronts which allows the ignition timing to be retarded, and gives because of that ca. 3% more power. For the same reason my four-valve car has 3 spark plugs per cilinder, which makes it more expensive to service. Here, again, the aim is to get shorter flame fronts and to avoid pre-ignition (pinking). All research has indicated that the average spark energy of an old, conventional system with breaker points, is already approx. 40 times the required energy, let alone that of an electronic system! Once the spark, however small, has ignited the mixture, the resulting flame front is so much bigger that the iniating spark is of no consequence.
And that's precisely why I use two spark plugs per cylinder: two burn the stick from both sides. I recommend that you study the research on this. I don't know your education on this matter, but I'm a university graduated mechanical engineer, and have been a successful tuner of racing motorcycles. And herewith I end this conversation.
resistance in ignitions are bad for fuel economy haha
I think they did it so it can distribute the Power evenly. Since some Spark Plug Wires are " LONGER " than the other... Only way to get Electricity to go evenly to " ALL " of your Plugs is put in a Resistor. In reality, you don't need them, but because Power must distribute evenly, they put the Resistors in them.

Builsed
That is the MOST STUPID THING I'VE SEEN,in 47 years of doing mechanics!!
Just BUY the non-resistor version of the plug.
Also,the resistor is there,to suppress interference,and it also affects the heat range !
The loss of any spark in a resistor plug is so small,it's a waste of money,and time!
Also the spark plug WIRES have more resistance,than the spark plug !
