What is your preferred spark plugs?
I use ngk tr6 , in my ls3
Have you tried different plugs if so was there a difference?
How is NGk performance in comparison with other brands?
I run NGK Ruthenium HX in my 2014 Mitsubishi Mirage. The best ones I've run were actually Pulstar, but they have major reliability issues.
Ngk
NGK Iridium spark plugs are the best in my 35 years of mechanic experience. I will use nothing less.
This basically sums it up.
How much miles can it last ?
@@steeviekouadio9311 80,000-100,000 miles on a healthy engine.
What about Denso Iridium?
@@seechurnkumarnitish4572 They are great too by my understanding.
I've been using the original Lancia spark plugs manufactured by champion for my Fiat Coupe. Recently I've swapped to Bosch and NGK. Didn't notice any difference but most probably by chance the NGK condition seemed to be better when removed. By the way all were copper spark plugs didn't uprage to any irridium or so.
Good job man. Thanks for all the time you put into this it is appreciated
Your video of the sparking is amazing and tells me a lot!! Thank you.
I run NGK iridium plugs. I can’t say I get more horse power but they went 100,000 miles and look brand new.
Use copper or silver.... Will get more output everytime but will not last as long as iridium
@@gj91471 .5-2 more hp vs ( likely same performance) and lasting over 100k is an easy play in my book
@@gj91471 You are right !. But It is difficult to find true silver sparks. What is your favourite spark ?.
@@gj91471 You'll never get a pony power more, whatever spark plugs you use!
I swapped out my stock plugs with iridium several yrs ago I notice slight improvement with gas mileage. Performance wise well good firing I lay into it too . Thanks again for this presentation nate
I owe all of the thanks to you.
@@NATESINTERACTIVEAUTOi have 1300 cc non efi which one is better to save furl and to enhance power and performance iridium ix,iridium power,iridium tough,iridium tt (titanium tip) , or double platinum????
NGK sparks looked more consistent and not jumping all over the place
NGK is the only way 🤘🏻
NGK Iridium to me Scooter
Build a compression chamber use an inert gas, pressurize and see which one fails to fire as you increase the pressure.
Esa es la mejor manera . Bajo presion
@@TheSol115 sure
Is your thinking that in an extremely inert environment the spark wouldn’t happen, because like lightening and thunder, the electricity rips the air to create the bang, but the air is only ripped/explosive because of the hydrogen and oxygen.. h2o.. so the spark should not spark because lack of combustible, ie “air”? But the spark combusts the diode, copper or iridium or platinum, or other? Not the air, or is the spark between the air?
You are correct that an inert gas test would be best
Now thats a test . He is basically making a cute spark machine. Put a spark plug inside a plasma ball be the new lava lamp .
I've been using E3 for the past few years. Totally dependable
I have used the E3 plugs and they are very good plugs. They perform real good. They are very good on gas mileage and they are hard to flood and they just crank right backup and keep going.
I've had my old school plugs for three years and still going strong
nice video！ can't wait to see your test the LED headlight!
I’ve been using NGK Iridium plugs for years, they’re very good plugs. I’ve also tried those Bosch Platinum Plus 4 plugs that were crazy expensive at the time and I ended up having trouble with them very shortly after. I didn’t notice any performance gains from either one tbh. My last two sports cars used the Iridium plugs straight from the factory.
Yes this seems to be a very good plug and the really last a long time. I appreciate you sharing it helps people that aren't sure because they don't have the experience yet.
iridium or laser iridium sir?
Need the rare earth element!
@@jamesbowen2105 We need it for sparkplugs.
@@ocrapo9327 exactly.
Always had good luck with ac delco copper plugs. Cool video would like to see more like this!
Im so happy to hear your experience, it helps people like myself in the NIA community know what to use and what not to use. Even more unbelievable you used some of your time to be kind to a stranger, that says what a good person you are.
Ok, here's the deal, copper is the best sparking plug but the center electrode wears quite fast. Platinum and Iridium are harder and more temp resistant. That's why they are used, to extend the service time. It can be extremely difficult to replace spark plugs in newer cars, especially V-6 front wheel drive cars. The cylinders facing the front are easy but the ones facing the rear are a pain, usually requiring removal of the intake manifold and cowl (where the wipers are) you don't want to have to do that every 30,000 miles.
Most complete & accurate comment so far. I've got a gen1 350 w/ high compression pistons that runs awesome on copper & so-so on iridium
@@thelion2358 yep got old school copper in my 302. as long as its a high energy electronic ignition (in my case the factory 1979 duraspark II), copper plugs are gonna work good
I've used E3s on two different 350 V8 Chevrolet Gen 1 engines, which work very well and are pre-gapped! The others are mediocre, in my opinion, and experience with all of these. Thanks for the video!
Its I that thanks you, first for the helpful information some people in the NIA community are trying to seek answers. So again I really appreciate you. Funny how a positive comment makes someone's day better.
I popped them in my mower I'm impressed I'll have to see how my 86 Nissan 300zx likes them over ngk
Gimik plugs, NOTHING, beats an Denso Iridium Spark plug, increased HP, better mileage and less emissions.. the E3 delivers not 1 of these improvements!
I have always had good luck using the factory replacement AC Delco spark plugs in my vehicles. I tried a set of E3 in my '79 Cadillac. They didn't last at all. Number 8 cyl kept fouling the plug out every few weeks. I put AC Delco back in the car and drove it another 2 years before I parked it for good and the plug didn't foul out. I wouldn't use an E3 spark plug in my lawnmower. I have also had good luck with NGK.
Had an e3 in my lawn mower for four years. Runs better still than when I put a new ngk in.
My 1.8t Audi engine tuned to 250 whp loves the brisk silver racing plugs.
Brisk, the best of the best
Wow cool video Nate. I appreciate your information and studies.
Its I that wants to thank you for the kindness, I really cant tell you how much it means to me.
@@NATESINTERACTIVEAUTO no no... Thank you. I watch ALL your videos and get a lot of useful information. I have been wrenching on my own cars since 16 and I am 50 now...haha. So yeah all these studies and the information found is very interesting and useful. Thanks again bud. Keep up the great works.
It really is great meeting & knowing there are good people like yourself out there so I am grateful.
@@NATESINTERACTIVEAUTO thank you Nate. You too.
I love your honesty;)
Replaced my AC Delco spark plugs on my 2005 Colorado with some NGK iridium with new boots. Noticed the difference immediately on startup and driving. Just hoping my truck stops burning gas so fast
Love the video but especially love the voice!!😅
I bought some E3's for my 06 trailblazer i felt the difference. The olds were just 3 1/2 years olds. The truck ran just. But i felt the difference 👍
Great test mate
Hey thank you for taking time out of your day to watch and comment, it means the world to me.
NFL plugs are for performance!!! Tried them in different applications(personal vehicles) . They are hands down a quality plug.
i would like to see an autolite vs ngk video with the pressure raising and raising until one fails and the other wins
For my sbc 350 circle track engine using cheap copper plugs and cheap cap and rotor i file the ground straps to a point. I do the same on the rotor button.
I first did these mods on my stock daily driven truck and noticed a difference and after several months i inspected inside of distributor cap and found no arc trails commonly seen on stock caps.
Plugs wore fine and any fuel mixture issues were easily visible.
Thats all folks.
I noticed the difference with the NGK iridium plugs compared to bosch; Champion; AC Delco and other brands is when used on a high performance engine mostly with some engine modifications.. When your using it on standard engines all of them seems the same and no significant difference... But once you advanced the timing or increase the boost pressure on turbo engine or run a high octane fuel... There is where NGK shines... The engine never bogs down or misfire on a dyno where other spark plugs does... BTW the car is a heavily modified Honda turbo civic I used it with... Running Hondata S300... You can see clearly on the dyno graph how each of those spark plugs behaves under intense boost
Can't tell you how many E3 plugs I've pulled from customers Camaros, Firebirds and Truck 4.8,5.3 an 6.0 LS engines that made them run like crap just to throw a set of NGKs back in and they run fine. But so far I've haven't had to change them out of a Mustang. Just seems odd the chevys didn't like em.
interesting...
I have them in a 5.3 and had them in a LS1 5.7 with excellent results. With other minor modifications my 250k Envoy XL 5.3 with 4.10 gears does 0-60 in 5second range, and has gotten as good as 24mpg driven conservatively. My relatively fuel-sipping Corvette LS1 saw a consistent 2mpg improvent with them too. Very noticeable improvement on every small engine I've installed them in, especially my Kawasaki Ninja and 2stroke motorized bicycle. My fuel-stingy Yamaha generator runs an extra 1/2hour on 1 gallon under same exact conditions compared to the NGK that came with it. On a tight budget E3s are best plug, Pulstar Plasmacore better if money is no object. (My personal experience with dozens of different engines and several types of plugs). No idea how you got your information, definitely not in line with my experiences!
One of the NGK with 3 something exploded in my 93 Audi C4 Quattro 2.6.
I changed back to the oldstyle, change them once a year and work's fine.
Next is the oil by an old Audi V6, keep by 10w40.
My young mechanic filled 5w30 in with the words; it's much better for your engine.
After 500 km the engine starts a clicking noise, I changed the oil back to 10w40 and it stops after 50 km.
Old Cars dosent like fancy mondern stuff I learned from that.
Regards from Denmark.
Thicker oil will mask some noise made by worn components. I'd keep an eye on your oil during changes. Make sure you don't see excess metal.
Call me crazy, lazy or busy, but I have a 2006 4.8 with over 220, 000 miles all on the OEM plugs. Maybe I have been lulled into thinking I have not lost any performance by it being my daily driver for 16 years. I am sure I have lost something yet my truck still has good throttle response and I have in the past towed a 30ft RV. Engine idles very smoothly. I am the sole maintenance guy on this truck but for the life of me, why I have not changed the OEM plugs or wires is beyond me. Maybe because I am not feeling any degradation in power. Not sure about the MPG from new.
Ac delco in all my cars and trucks. Champion in my small engines.
Just started using the E3 plugs in a 77 cj5 with a DUI distributor upgrade. HUGE difference!
sparks from e3 look brighter
What does that mean if sparks are brighter?
I’ve had issues with e3 spark plugs. Never a firing problem with the NGKs
In non turbo app bosch platinum plus yttrrium with 2-4 electrodes outperform and cost 4-6 dollars. If you have turbo an irridium or ruthenium plug is necessary with ruthenium out boosting and lasting irridium for a boost in cost also!
I have use E3 plugs in all my engines right now they’re installed in a 92 V-8 Dakota 95 v8 jeep And in my Buick Park Avenue v6 and I just changed a three-year old with 45,000 miles on them out of my 87 Dodge V8 and they looked pretty good still
I run those E3 plugs in my 06 mustang did definitely notice a performance increase with those plugs. I had quicker throttle response and the car actually gained a little bit of extra power I was impressed.
Lol....... Put your car on a chassis Dyno..... You will find no difference.
Thats very interesting no doubt. I have used them some.
It can be really hard to notice a difference, especially when the gain is small but I have seen dyno test show no improvement and on a different test and circumstances there was a difference.
@@NATESINTERACTIVEAUTO Usually we think we have made a gain but this is very rare.
The side electrode can be cut back and the end of the electrode likes a 180 degrees radius.
It's torque you should be looking at.
Torque = the ability to do work.
Power is not used in normal day today driving.
Power is just a calculation
For maximum economy, the copper plugs are the way to go. When I had my Focus, the OEM plugs were platinum, but replacing them copper plugs delivered a constant improvement of 1 mpg city, 2 mpg highway. The copper plugs can deliver a hotter spark due to less resistance to voltage loss. Yeah, they needed replacement between 12 to 15k miles, but if your thrifty or looking for better economy and/or performance that's the way to go. D
Thats very insightful, Thanks for all of the information. What brand do you prefer?
@@NATESINTERACTIVEAUTO
IMHO, I don't have a favourite brand; in my case with the Focus it was because the Motorcraft copper plugs were the cheapest. Having said, I normally would start with the OEM manufacturers recommended brand of plug. Engines are like people, each one is different, I once had a Chevy 2500 and the factory AC Delco plugs were garbage. Experimented with NGK, Autolite, and ended up with Bosch working out the best. Sadly, these days many of engines use highly extended reach plugs that have no copper equivalent, so only expensive platinum or other more expensive plugs will work. But, even there you can, if you or so inclined, experiment with different plugs to see what works best for your application.
@@oldguy2082 my thought also: each engine needs its own plug
Would this still apply to boosted applications? Just wondering because of the difference in compression and conditions inside the combustion chamber
@@smooth_orange2798 I don't think that a copper plug would work well in boosted applications. The higher temperatures, higher compression would probably lead to very short plug life, which is why platinum or higher grade plugs are exclusively used in turbo or ultra high compression motors as an OEM plug.
Great video. Actually, i have two police cars, Crown Victoria and an interceptor utility that i need to remove the intake manifold to charge the plugs,They used Motorcraft platinum plugs, and the performance is excellent .
How often do you have to charge them ?
@tubetime39 perhaps about 100k miles, mybe check them for gap about 70k miles .
would love to see the same plug with and without resistor built in tested side by side in the tester you have
My idea of testing would be…..
Run 4 different plugs in a vehicle then bring them back to the bench to see how the spark and temps are with carbon build up on them. I personally feel an spark plug will spark and do it’s job, but how’s does it react to carbon build up and exposure to engine heat. I also feel the plus with the needle like core might prematurely fail quicker due to lack of surface area and carbon building up on the tiny needle like core. Just my thoughts. And maybe that’s why E3 is confident giving the warranty they give on their products. I race motorcycles in endurance races. I’ve always been parcial to NGK in anything made in Japan. But I have a KTM (Austrian) dirt bike and I have had NGK prematurely fail leaving me changing a plug miles out in the woods. I tried E3 and I haven’t had a single plug fail YET. I’m running the trails, same fuel, same jetting on the carburetor. I would have no issue sending you a NGK and E3 that I’ve ran in my bike for you to test on the bench if you would like. They would both be run on the same track for the same amount of time so it would be a fair test.
I appreciate the “good ol’ boy” accent. Great video and keep testing.
Remember the plugs from JC witney and claimed to fire in oil?
Run E3 plugs in most of are atv,dirt bikes and three wheelers. They are more foul resistant. We street ride two Honda Dax 50’s hundreds of miles a summer. We would foul spark plugs probably every two trips with regular NGK or Champion plugs. Converted both bikes to take E3.24 small engine plugs only used two plugs total since the conversion. They also foul a lot less in 2 stroke engines when trail riding.
I've experimented with many different plugs in my 11' Audi A4 quattro 2.0 tfsi b8 . This car is known for carbon buildup due to direct injection amidst other things, therefore I've found that iridium doesn't carbon up like the factory "Double Platinum" does. I've tried NGK & Denso in copper, Platinum, double Platinum and Iridium. I personally like the Denso Iridium power the best. They seem to burn off the carbon due to extreme heat range. Just IMO..
Audi original sparks are BERU brand. Test BERU Iridium sparks.
Best plugs I ever ran were Pulstars, at first. They have major reliability issues. Longest I had a set last was 10k miles before the ceramic insulator broke apart. NGK Ruthenium HX comes in a close second and is crazy reliable.
Agree, I have 2 heavily modded Ecoboost engines, pulled set out of f-150 after 45,000 miles and the gap was the same, .030. ruthenium rules.
Best plugs you’ve used lasted 10k miles. What makes them better than a equivalent performance that lasts 10x’s that.
@@freebehindbars8654 I think he was saying that the longest a set of Pulstars lasted for him was 10K
@@NordicDan That first sentence says otherwise. He was fine with 10k, since they were the best plugs he’d ever used.
As far as the best plug made, that I’ve used. NGK Iridium IX. We have service vehicles that get abused and pulled a set with 90k on them, zero wear and perfect color. Hooked it up and it’s running the same as the day I installed them.
I would have turned down the voltage until each plug stopped firing. Other that that, all this was was a pretty light demonstration.
My spark plugs are about $2.50 a piece... I have a custom turbocharger set up that I did so I run a one step cooler (than stock) plug and change them frequently... don't get taken in by expensive spark plugs... all you need is for it to light off... a flame kernel will burn everything in the cylinder....been running them for ~15years no issues
I find the same thing, anything boosted. Better just use copper core and run the suckers. So many cars with misfire issues and surprised when $2.00 coppers run like a champ.
I agree, spark is spark.
I’ve been using E3’s almost since they first came out. Personally I think for NA set ups they work great. Always noticed a better throttle response for sure and increase MPG by around 5 miles per gallon. Mostly 4 cylinder engines and 1 6 cylinder.
How about for Turbo Engines?
@@MB1Billion I’ve heard they aren’t great in turbo engines but I don’t know for certain.

@@RJ7heGrreatI've been running E3 plugs in my 2.0l LTG Turbo Buick for a few weeks now. Been rather happy with them even if people crap on the brand a lot. Been using E3 plugs for my other cars too. Been a good result
Hi, any recommendations between Bosch double iridium and NGK laser iridium for the best power performance? (Im using Mercedes A class w176 petrol)? Thanks
I am using E3 in my heavy duty mowers. Never had a problem.
When we clean spark plug using sand paper, will the remains of the sand on the spark plug affect the engine any way like damaging internal parts?
Now is this best performance as In how does the plug performan and last I'm an oe application. Or is it which plug is best for a high performance application? Cause alot of time iridium isn't the best option for a turbo application along with platinum because it holds heat and causes detonation.
On a raptor 786 motor with 11:1 compression piston running on premium pump gas what plug heat range do you reccomend? Go with the *9 or the *8?
I don't think this type of testing really proves the performance of brand new spark plugs. That can only be done with actual performance testing in an engine. My newly rebuilt ( last August ) 2.7 liter ( 4 cyl ) 3RZ-FE engine ( Tacoma 4x4 ) ran excellent with the regular NGK Iridium plugs. With only 12,000 miles on my engine & these plugs, I decided to switch over to the newer NGK Iridium IX plugs, that feature the tapered tip on the strap. NGK claims this new design decreases quench in the combustion chambers. My regular NGK Iridium plugs revealed perfect, normal wear on all 4 plugs, they looked identical. So I know my engine/ignition/timing is dead-on. But even so, I noticed a slight performance gain after switching to the NGK Iridium IX plugs. I had also installed a set of Magnecor 8.5mm ( KV85 ) plug wires, which definitely delivers 100% of the energy produced from your coils. TIP: to ensure the best performance & durability from plug wires, NEVER pull plug wires loose, unless it's a roadside emergency, or you are replacing plugs or plug wires themselves. And even then, ALWAYS pull plug wires when your engine is totally cold. Pulling good plug wires loose when the engine is at or near running temperature, will wallow out the plug wire connectors because both spark plug end connectors and plug wire connectors expand with heat. This causes the plug wire connectors to have a poor fit to the spark plug, and performance & fuel economy suffers. Pulling plug wires when the engine is totally cold minimizes the risk of wallowed-out plug wire connectors. ALSO: Really good plug wires are just as important as good spark plugs.
Best is to stay with identical OEM, or risk problems…speaking from experience with many cars.
What If the OEM gap is 0.9" and you change to a Ruthenium plug that has 1.1" gap ?
Is that significant enough to cause issues?
Everything else lines up mind you: thread diameter, thread reach and hex size.
I tried all the plug types in my 95 tbird. Super ez to put plugs in. For the money? Copper. I had a msd system on it and I could open the gap
I stick with NGK or Denso platinum or iridium depending on budget.
What about using a multi meter to check the resistance?
Running a honda 4T trail bike single on NGK standard plug all was well but I tried the NGK iridium plug. On the standard plug huge bright blue spark. The iridium plug couldn't see the spark but bike started easier ticked over better came off choke quicker and ran more smoothly. There wasn't any problems with the standard plug but the iridium was better. TL 125. If anyone's is interested the engine is quite and tighter sounding. Difference between a Timex watch and a Rolex.. both work but one is better. Plug cost £10 apposed to £4 on eBay.
Its all marketing, someone is always trying to sell you something.
In my opinion, Copper Core are inferior to the competition. With today’s EFI and electronic ignition systems, copper core will last 100k miles, I’ve done it personally.
The only reason copper core gets a bad rap is back in the carburetor days, lots of cars ran rich on fuel, quality of the oil was also not as good as today. This caused fouling of the plugs. Hence the premature failure.
I feel like the E3 is a good copper replacement for older cars just because of how large area that needs to be fouled out before they lose there efficiency
Copper is a softer metal. For this reason, it will simply not last as long as Iridium plugs (extremely hard metal, with excellent conductive qualities). Im an electrician and a mechanic.
Hello my friend, what is the best type of spark plug, NGK or Bosch?
In my 4.3 l V6 I put NGK iridium spark plugs in it it ran okay and then while on a delivery only 2 months later it was missing obviously I thought it was something else took the spark plugs out sure enough I have never seen a weaker spark put the old copper ones in after a little cleanup I'm sure I can go a hundred thousand miles on it and it's stronger than ever
Copper plugs won't last over 30k miles the electrode wears down.
Would you test champion plugs
I have a 2007 E550 with 150k miles and stock plugs still inside I think. I was wondering What would be better choice. Denso iridium power 5353 ixuh 22 plugs or ngk 5353 iridium ix plugs?
I saw the show power nation simply install the E3 plugs on a Dyno and the engine picked up about 9HP just by changing plugs over a good quality plug but at $10 a plug not sure I want to do that.
I've used e3 plugs on my lawn mower to see what the difference would be. It had more power and better mileage . Its easier to determine how much gas you use with a lawn mover because i use it the same every time. Anyway the plugs did not last one season..
It was in your head.
My choice is E3 for my beefed up Honda Ej8 coupe and AC Delco for my GM car
Back then (last year) I was a crackhead of a driver sliding and racing in my 150hp 1998 honda odyssey across the land. Still ended up with 30highway and 26combined with e3 spark plugs. Also installed a full custom exhaust to the cat and short ram at the same time so I'm not sure how much the spark plugs contributed to fuel economy but I do know that the odyssey was supposed to do 24highway and 21combined.
Gonna put some e3 sparkeronies in my 8th gen honda accord 6-6 and see if it explodes. Almost at 295k km and still whip it like a true crackhead would. You can drift anything if you believe in yourself. Will come back in a couple of months.
Also it has a muffler and resonator delete. I have embraced the rice life and hate myself for it. All I need is a short ram and some nice exhaust tips and some cringe amazon banner that probably says locally hated but in japanese 😂

Does switching to iridium spark plugs improve engine smoothness and better throttle response in lower gears?
If your car came with Oem copper stick with copper! dont upgrade to iridiums or platinum, you will have power loss.
It wil be a little bit smoother with iridiums and last much longer, but there will be power loss.
And also copper spark plugs are much more powerfull than iridiums or platinums.

Think copper plugs are going to give you the best performance but they won't last as long.
You are right !.
Rare metal plugs last longer but Copper plugs Burn fuel better and more properly due to larger stronger spark.
I only use the good old champion copper core plugs....
I've seen real-world testing, and e3 came out on top, with ngk in second
LOL
It is easier to see on the E3 plug, and the Copper AC Plug, You can see the Spark jumping to or from the Sharp Edge of the Center Electrode, and it is still visible on the Smaller Electrode Plugs. Sparks do like a Nice Sharp Edge. All Plugs new, but I wonder how each will perform as the Electrode Wears? I will put my Money on the much smaller Platinum/Iridium Center Electrodes

Is it Okay to switch to NGK's if your car came with AC Delco's ....??
In my case a 2011 GMC Terrain
Yes, there should be no problems.
Can you test nitrode spark plugs 🔌
I've ran the E3 spark plugs before on motorcycles and they didn't last maybe a year at best, and they weren't as good as Ngk spark plugs. And the E3 spark plugs cost almost as much as the Ngk iridium spark plugs.
what do the results indicate?
Try checking the ohms
So far E3 seems to have larger / stronger current output, compared to the NGK.
The Black Ac Delco spark plug seems to have larger / stronger current output, compared to the Silver Ac Delco spark plug.
Overall it seems the E3 takes the 1st place.
Black AC Delco takes 2nd place.
Silver AC Delco and Ngk takes 3rd place.
94 GMC K1500 with 350 5.7 liter... 255K on the engine if original which I'm not sure... Used AC Delco and notice a miss so giving the NGK a shot and see how that works....
I always wondered how the plug warranty works.
Technically the plug doin what it’s supposed to from the point you switch them out is better performance. That’s just a pretty way of saying so.
You shoulda compared Autolites there a super cheap plug too
