Great video, lots of conflicting info (from seemingly solid sources) on this subject all over the interwebs. I just crossed 40k and this has been on my radar. Thanks
Thanks man, much appreciated! I will stick with the OEM plugs ;-) Interesting to hear the replacement interval BMW recommends. My BMW dealer (Europe, The Netherlands) recommends to replace mine before the end of this year when my 440i is three years old and has done about 50k km's (31k mls).
I replaced my 340i champion spark plugs with ngk and they caused a bunch of misfires. Replaced those with new champion spark plugs and all the misfires went away
So I have 16 340i and you have convinced me to replace with the champions! No doubt......I’m at 32k and at 29k I flashed a BM3 stage 1 tune with no mods. I heard from a lot of people that you don’t have to change plugs with a simple stage 1 tune? But I’ve also heard some say you should immediately change plugs with even a stage 1 tune? So that’s my first questions Second question is when plugs are changed should you also change ignition coils as well? My next oil Change is at 35k and I’m pretty much convinced at 35k I should change plugs ( if I wasn’t tuned I guess I would wait til around 50k ) ....... Thx for your help
Changing plugs isn't required when tuned but you're already at the mileage where plugs should be changed. If you haven't changed them already it's definitely a good idea. Coilpacks don't need to be replaced.
@@scottjohnson8316 the bmw service interval is 6 years/60k but i do 3-4 years/30-40k. You can always inspect them and if the gap is good and they don't look to worn out then run them for longer. It's not necessarily going to be the same for everyone
Hey great vid. I have a 2017 540 that I’m looking to do a stage 2 tune on. Currently have 40k miles with original plugs. I planned on changing them when I tuned since I was close to the recommendation anyway. The tune company recommends going a step colder and changing every 20k miles. Is it worth going colder?
Temperature range is set by individual manufacture standards means every one calling own numbers. If NGK tests those Champions plugs you getting NGK standard with number 8.
i installed the 97506 on my b48 330i today. since the guy i spoke to recommended them. gonna run some logs and see how they behave. went for a drive and everything seemed normal. if there's a misfire, i'll go for the 94201
That answered a lot of questions I didn’t even know I had, thank you. I’ve been having random RPM dips during idle. Could I have accidentally gapped a plug too narrow? Or would that be totally unrelated?
Hey I have a 2016 340 and I'm about do a stage 2 MHD tune. The car has ~52k miles on it so I want to make sure I'm covering all my bases before I put more power to it. I was hoping u could give me your opinion on what I plan on doing: Coils + Plugs (Which coils do you recommend Bosch or Eldor?) Oil change (No help needed here) VRSF Catless DP Diff flush (Should I do front and rear? Any info on the intervals?) Transmission flush (Might wait till 60k? What do you think about this?) Lastly, is there anything else I should consider? Thanks, Justin
My G32 b48 had genuine Champions, but I replaced them with NGKs, the engine ran much smoother, but after 500km, I checked the plugs and the white isolators were so white like new. So I replaced them back with Champions, being afriad of preignition.
Those Ngk's are all the same, when you buy a new set of plugs they perform great for a little while, after break in period car runs more rough and sluggish. But never had this issue with the Champions they perform excellent using it for a year now.
Hi Kern, I'm seeing almost everyone put 94201 NGK in their BMW B58's, both TU and non TU. I have a B58TU motor, and according to this video, the plug for my motor is the 95248. I contacted NGK and they did not provide any additional information for me. Could you potentially provide more insight on this?I don't want to put the incorrect plugs in and the only people who are putting 95248 plugs in their BMW's are the S58 guys based on me skimming through Bimmerpost. Thanks in advance for your reply and insight.
I like your channel I have a 16 340i xdrive with only the BM3 stage 1 .....stock everything else I was definitely interested that Dinan carbon fiber intake so I emailed PTF asking them about using the aforementioned intake with my already flashed stage 1. They responded saying leave the stock air box don’t use any intakes...and that PTF doesn’t recommend intakes for either stage 1 or stage 2!!! I could of copied and pasted from there website where hey actually DO recommend an intake for both stages! Maybe they changed their philosophy and didn’t update the website? Anyhow that was a good point to reflash after intake installation...did you notice any increase in mid to top end power? I know the sound isn’t much louder which is good. Why would PTF be so against adding an intake? Especially the Dinan one which simulates the stock one? Also in regards to spark plugs. If I stay stage 1 and when I finally do my plugs should I just replace with the stock ones? Also I’m at 30k and figure changing them at 50k....I thought that would be a good number to change them. I mentioned replacement with stock ones simply because I don’t think a stage 1 340i has enough HP to justify one step colder? Thanx
When they say not recommended, they mean that Intakes aren't needed and don't add much power. Some intakes that don't have an enclosed box can actually reduce hp. Dinan is fine but didn't make the car any faster in my testing. Replacing with stock plugs is fine.
yeah the intakes doesn't add any HP which is why they probably saying they didn't recommend. I run an MST intake (closed box) on mine (same exact car as you) and it literally didn't add any HP. Kies Motorsports did a dyno video on it. The induction sound is all you get from it which really changed driving the car for me haha. I love it. And TRUST me, do that catless Downpipe and go to stage 2 bm3. The car is so much better.
Is it good practice to change the ignition coils at the same time? Juat hit 50k, and I needed to replace my Downstream O2 sensor, so i thought I might as well change my plugs. You nall think i should change both O2 sensors, too?

Had no idea Champions were considered colder. My tuner insisted on the 94201’s when they came out, claiming the Chanpions had a reliability issue and longevity concern. Thoughts?
Some people have had issues with both, so i don't believe it's dependent on one brand or the other. But NGK is the most trusted brand so most people recommend it.
My 440i is at 30k ish miles and have been experiencing some low speed jerking, especially during traffic in low RPM. I also see the RPM dips when idling . Brought it to dealer they could not dingoes out and said it might be the wore tires which I was really doubtful about it .. I have new tires now but issue still exists. Do you think it could because of bad spark plugs?
Hello, I own F20 120i with B48 engine. Do you suggest in any case to mantain OEM Sparkplugs (SILZKGR8B8S)? Some people suggest to install SILZKGR8C8S as an upgrade. I'm going to flash stage 2 to my car and I don't know what to do. Thank you
I just went to stage 1 and logs start show many timing correction (up to -5-6) in all cylinder in whole rev range. Not sure if it’s the bad fuel quality or worn coil pack (87k miles on them). May the gap reduction a good idea to solve this timing problem?
I was watching this and just two questions. About the last NGK that were recommended for N54, N55, etc for being colder. Isn't the connection the same than the champion spark plug for the b58? Al the spark plugs in the video has the same connection except the NGK for B58 or am I wrong? And another question. Mahle has forged pistons for B58 that lower the compression and theorically you can install them on new and old b58. On older engines you would lower compression to the same on the new B58 (10.5:1). Would be better in this situation to use the newer B58 spark plugs?
Not sure what you mean by connection but just use the plugs designed for your car There's no need to drop the compression in your engine and no need to change plugs
@@kern417 Sorry, youtube didn't notified me of the answer. With the connection I mean that you say in the video that we shouldn't use the NGKs that were recommended for the older N54 and N55 because the metal conenection in the upper part of the plug, the part that connects to the ignition coil is different and the connection would be worse. But watching the video, the connection of the older NGKs and the Champion for the B58 Gen 1 is the same. So that shouldn't be a problem. About lowering the compression...I meant, in case you wanted to install the mahle forged pistons. Because Mahle only has forged pistons with 10.5 to 1 compression. So if you want to install mahle, it's the only option for the gen 1 b58. Couldn't be possible to install them? Thaks for answering
Watching this video now and noticed FCP euro recommended the NGK 94201Gen 1 plugs so I got those but your video is saying to go with the NGK 95248 since I have a gen 2 motor. Should I start an exchange process on that or will I be ok just dropping them in gapped at 0.030 on a factory tune. Thank you!
Hello can someone help me. So I flashed an E 40 map on MHD. But I noticed right before I hit the long write button it says OCT 95.. so I went back and clicked e85 and it shows up as e40.

Hello I look some people replace sparks plugs on b58tu M140i By supra sparks plugs What do you about this ? Supra spark plugs it's to long to b58tu sparks plugs
@@kern417 I’ve heard the tu plugs reduce corrections as well , I’m running stage 2 plus with b58tu pump and plugs gapped to 0.022 , would going back to stock plugs and stock plug gap be better and help timing corrections Thanks 😊
I have a 320i 2017 b48 40k miles i changed them today for the first time and they were ngk and i bought champion is there any problem changing them to champion ??
I bought the old n55 style for my 2nd gen b58. Guess I'll send those back and get the stockers. I guess if the possibility of the champions being one step or 1/2 step colder than those are probably best option. Doing the bm3 ots stage 2 e30 tune and it'll be auto x raced quite a bit. Thanks for the video
Hey Kern! I’m having a problem holding consistent timing across all cylinders. I have the 1st gen B58 with stock NGK plugs. I’ve replaced the plugs with oem NGKs with stock gaps. I have access to 93 Octane fuel and running a 91 octane map because my timing was really bad and had a knock sensor with the 93 ots map. Any ideas of how i can clean up timing? Im using shell vpower 93 if that helps. Only mod i have is high flow down pipe.
Just sent some logs to your IG if that helps. In some instances its pulling more than 3 degrees timing in some cylinders. Im assuming next steps would be adding e85 or checking my air filter someone mentioned to me. Seems like re-gapping plugs is not needed but open to your thoughts. Feel free to respond here or IG. Thank you.
Bosch all the way for my car, a GM, (made in Russia nowadays these plugs it seems, unfortunately). Better price I could get them for than others, also more mileage than 'standard' ones. They accidentally sent me 2 boxes, only paid 1, so a free change next time !
Hey, I figured my 2018 b58 problem, burned spark plugs, second time and car has 30k miles.. Any idea whats causing it? Should i change coils too? And i dont drive it hard..
@@kern417 plugs were oily, well the 6th was. I took it to the dealer since the car is under warranty, and they checked turbo, cylinders all ok, but found the membrane on the valve cover failed. THey found oil in cylinder 6. I had missfire error... Shouldn't they change whole valve cover, since the problem got so far?
u had same question but i got supra 2020 and have all those but am going with pure 800 turbo on 91 octane aggresive custom tune bootmod3 mikeboti tune should i upgrade to ngk ?
kern417 I ordered them thru fcpeuro and return them when I saw that and my local Bmw dealership And it came the same but the guy swap the champion for 4 NGK for me
I hear so much about setting the gap correctly. But I thought they were preset. So how do you gap a spark plug? 🤔. Does it take s special skill? I want to make sure the shop I take it to does it correctly.
They come to a set gap, and you can change the gap based on your setup. For 99.9% of users, i would not recommend changing the gap. Unless you are running extremely high boost levels or ethanol content.
I checked new plugs and one was at a solid 0.031. So over spec. Everyone also seems to be talking about either stock 0.030 or 0.022. But you can do for example 0.028
@@kern417 This gap is very confusing. Especially with all the tuning shops recommending reducing the gap. I have read somewhere that 94201 design allows for a bigger gap. Maybe people switching to 94206 has to reduce the gap. I think I will gap them at 0.028 as the also increase the gap as they wear, so it will leave room for that. Where do you find the accepted specs? Service manual?
Correct. If anything it would reduce efficiency because the location is set based on the injector position, piston design, intake valve location, etc etc etc.
Another great video! I went from fairly new stock plugs to the TU plugs and i got a good increase in throttle response. The car just takes off with little throttle. This is mostly part throttle but full throttle was better too. Gas mileage went down. I felt a slight delay when quickly going full throttle sometimes then it just goes fast. Car was slightly too responsive so I gapped them down to about 0.22 which solved both issues. The plugs didn't solve timing corrections though. My theory behind the responsive throttle is the higher compression engine with a plug tip firing deeper in the chamber. Could also be quicker burn rate. Running stg 2 hpfp MHD.
@@Addselwyn it really depends. Not too bad on stage 1 93 octane map but corrections can happen on any map usually in my case due to DME managing traction even with DSC off. Some days corrections can be pretty bad until DME adapts to conditions like weather and road or traction conditions. I'm on a custom e60 tune now and it's quick but corrections can be aggressive in higher gears like 4 and 5 until DME adapts and things look better. Lower gears not so much corrections. Usually, corrections occur when I punch it 3500-4k rpms right where torque is really high and wheels want to spin. If I start really low in the rpm like 2500 4th gear pull, it can be better at times. It seems the better roads I'm on gives me the best logs. Very difficult to get rid of them because DME uses ignition to reduce power to the wheels in certain situations. Some tuners are reducing knock sensitivity. I don't think it's worth it. I've learned to ive with it. Hopefully, some torque or throttle limit table will be discovered to help this in the future.
@@brakthru2 hi thanks for the reply it’s very interesting and I am now understanding more about timing corrections and why they happen , I’ve had a custom tune and get some timing corrections and have been worried about damaging my engine , my car only has 8000 miles m140i , I’m also using the b58tu plugs , I’m going to try ngk 94201 next , thanks again 👍
Ofcourse I have also noticed that all my cars run much stronger and smoother with the Champion spark plugs. I only had NGK before forget Ngk I can recommend the Champions to anyone who cares about performance and smooth driving.
Larger spark plugs gap only for non-turbo engines. Small spark plug gap for turbocharging engines Larg gap in turbocharge engine gives you a misfire and poor performance. Those colder is better sounds like grandmother dres' wormer only. Manufacture know the best heat range for any engine. Needs to know factories are paying great penalties to governments No one can achieve fuel efficiency what Governments are asking. Those magical words or sounds like miracle spark plus means nothing only personal filing before or after orgasm. Iridium or what so ever metal is used this only money grab. Better conductivities and for what when from coil getting up to 40.000.00 Volt. Those super metals only can last longer than regular iron. The most important is the porcelain at the middle electrode. During the combustion burning all additives in the fuel and the engine oils. Lots of metal plus carbon is conductive. Same time become a resistor. The porcelain covered with carbon and metals ground high voltage Electrodes may look nice and spark plugs no good or not efficient. The best Spark plugs are with copper or silver electrodes. Needs more frequently replace them.
I bought the ngk 96206 plugs for my 21 m340. SILZKGR8E8S. Are these good to put in? I read to get the 96206 over the 94201 plugs. Any truth to this? Honestly after watching this, I’m inclined to ditch the ngk plugs for champions 😂

About lowering the compression...I meant, in case you wanted to install the mahle forged pistons. Because Mahle only has forged pistons with 10.5 to 1 compression. So if you want to install mahle, it's the only option for the gen 1 b58. Couldn't be possible to install them?
Thaks for answering
They are not the same. The new ngk 94201 is the same as the champions because theyre both made for the B58 unlike the 97506. Watch the video again.
@@kern417 Yes, sorry last day I watched the video I saw it wrong, I don't know why.

G01 x3 m40i stage 2 e50, what gap do you recommend for champion plugs
Watching this video now and noticed FCP euro recommended the NGK 94201Gen 1 plugs so I got those but your video is saying to go with the NGK 95248 since I have a gen 2 motor.
Should I start an exchange process on that or will I be ok just dropping them in gapped at 0.030 on a factory tune. Thank you!
If you have a gen 2 then get 95248
Great video 👍
Appreciate it
Hello can someone help me. So I flashed an E 40 map on MHD. But I noticed right before I hit the long write button it says OCT 95.. so I went back and clicked e85 and it shows up as e40. I wanted to check my settings and I noticed this. So I’ve been running e40 on the oct 95 map for 2 months now. Can anyone explain this. Thanks
No. Message mhd.
Hello I look some people replace sparks plugs on b58tu M140i
By supra sparks plugs
What do you about this ?
Supra spark plugs it's to long to b58tu sparks plugs
Is there any advantage to running the TU plugs in a Gen 1 B58? See lots of ppl say it reduces timing corrections when tuned?
No there is no benefit
@@kern417 I’ve heard the tu plugs reduce corrections as well , I’m running stage 2 plus with b58tu pump and plugs gapped to 0.022 , would going back to stock plugs and stock plug gap be better and help timing corrections
Thanks 😊
I have a 320i 2017 b48 40k miles i changed them today for the first time and they were ngk and i bought champion is there any problem changing them to champion ??
No it will be fine
From what i remember bmw recommends Champion
I bought the old n55 style for my 2nd gen b58. Guess I'll send those back and get the stockers. I guess if the possibility of the champions being one step or 1/2 step colder than those are probably best option. Doing the bm3 ots stage 2 e30 tune and it'll be auto x raced quite a bit. Thanks for the video
No problem man. Glad i could help.
It’s on the F&G b58 mhd
Hi, can you please tell me the the cylinder numbers? Is cylinder 1 closest to the front or rear? Thanks

What do you recommend for a pure800 stage 2 gen 1 b58? The gap spark plug
Stock plug stock gap
How about Bosch super 4 or something? Or stick with oem?
What about for higher horsepower b58’s 650whp? Stock is fine?
Yes

How si there not a compatible bosch? They make a lot of the M plugs and plugs for Porsche 911’s… they can’t be inferior to NGK from that perspective
Just because they make plugs for other cars doesn't mean they can't be inferior.
I run "ChicknWang" brand spark plug.
Never had a problem.
Hey Kern! I’m having a problem holding consistent timing across all cylinders. I have the 1st gen B58 with stock NGK plugs. I’ve replaced the plugs with oem NGKs with stock gaps. I have access to 93 Octane fuel and running a 91 octane map because my timing was really bad and had a knock sensor with the 93 ots map. Any ideas of how i can clean up timing? Im using shell vpower 93 if that helps. Only mod i have is high flow down pipe.
The easiest way is to add 1-2 gallons of e85. How much timing is being pulled?
Just sent some logs to your IG if that helps. In some instances its pulling more than 3 degrees timing in some cylinders. Im assuming next steps would be adding e85 or checking my air filter someone mentioned to me. Seems like re-gapping plugs is not needed but open to your thoughts. Feel free to respond here or IG. Thank you.
Hey man what’s your ig I got some questions!
Kern417
Bosch all the way for my car, a GM, (made in Russia nowadays these plugs it seems, unfortunately).
Better price I could get them for than others, also more mileage than 'standard' ones.
They accidentally sent me 2 boxes, only paid 1, so a free change next time !

Same happened to me from bmw dealer but 4 ngk and 2 champions. Dont try it out runs rough.
Is ngk is the best with mhd stage 2 tuning
I hear so much about setting the gap correctly. But I thought they were preset. So how do you gap a spark plug? 🤔. Does it take s special skill? I want to make sure the shop I take it to does it correctly.
They come to a set gap, and you can change the gap based on your setup. For 99.9% of users, i would not recommend changing the gap. Unless you are running extremely high boost levels or ethanol content.
@@kern417 thanks 👌🏾
I checked new plugs and one was at a solid 0.031. So over spec. Everyone also seems to be talking about either stock 0.030 or 0.022. But you can do for example 0.028
0.031 is in spec
@@kern417 This gap is very confusing. Especially with all the tuning shops recommending reducing the gap. I have read somewhere that 94201 design allows for a bigger gap. Maybe people switching to 94206 has to reduce the gap.
I think I will gap them at 0.028 as the also increase the gap as they wear, so it will leave room for that.
Where do you find the accepted specs? Service manual?
Would the deeper burning electrode of the TU plug not do any difference whatsoever compared to first gen plug?
Correct. If anything it would reduce efficiency because the location is set based on the injector position, piston design, intake valve location, etc etc etc.
Hi, I have M140i (B58 1gen) with Supra (TU) HPFP and MHD Stage2+ E40, what Ido you recomend ?
Exactly what I said in the video

@@gtmautomobiles3005 stock champion or ngk
@@kern417 ngk with 0.22 gap or don't change ?
Another great video! I went from fairly new stock plugs to the TU plugs and i got a good increase in throttle response. The car just takes off with little throttle. This is mostly part throttle but full throttle was better too. Gas mileage went down. I felt a slight delay when quickly going full throttle sometimes then it just goes fast. Car was slightly too responsive so I gapped them down to about 0.22 which solved both issues. The plugs didn't solve timing corrections though. My theory behind the responsive throttle is the higher compression engine with a plug tip firing deeper in the chamber. Could also be quicker burn rate. Running stg 2 hpfp MHD.
What are your timing corrections like
@@Addselwyn it really depends. Not too bad on stage 1 93 octane map but corrections can happen on any map usually in my case due to DME managing traction even with DSC off. Some days corrections can be pretty bad until DME adapts to conditions like weather and road or traction conditions. I'm on a custom e60 tune now and it's quick but corrections can be aggressive in higher gears like 4 and 5 until DME adapts and things look better. Lower gears not so much corrections. Usually, corrections occur when I punch it 3500-4k rpms right where torque is really high and wheels want to spin. If I start really low in the rpm like 2500 4th gear pull, it can be better at times. It seems the better roads I'm on gives me the best logs. Very difficult to get rid of them because DME uses ignition to reduce power to the wheels in certain situations. Some tuners are reducing knock sensitivity. I don't think it's worth it. I've learned to ive with it. Hopefully, some torque or throttle limit table will be discovered to help this in the future.
@@brakthru2 hi thanks for the reply it’s very interesting and I am now understanding more about timing corrections and why they happen , I’ve had a custom tune and get some timing corrections and have been worried about damaging my engine , my car only has 8000 miles m140i , I’m also using the b58tu plugs , I’m going to try ngk 94201 next , thanks again 👍

BMW recommends Champion tho
Ofcourse I have also noticed that all my cars run much stronger and smoother with the Champion spark plugs. I only had NGK before forget Ngk I can recommend the Champions to anyone who cares about performance and smooth driving.
You’re not fooling us by saying you learned on the forums. We all know you read the b58 user manual religiously.
Please keep this to yourself. I have a reputation to uphold. 🤐
Larger spark plugs gap only for non-turbo engines.
Small spark plug gap for turbocharging engines
Larg gap in turbocharge engine gives you a misfire and poor performance.
Those colder is better sounds like grandmother dres' wormer only.
Manufacture know the best heat range for any engine.
Needs to know factories are paying great penalties to governments
No one can achieve fuel efficiency what Governments are asking.
Those magical words or sounds like miracle spark plus means nothing only personal filing before or after orgasm.
Iridium or what so ever metal is used this only money grab.
Better conductivities and for what when from coil getting up to 40.000.00 Volt.
Those super metals only can last longer than regular iron.
The most important is the porcelain at the middle electrode.
During the combustion burning all additives in the fuel and the engine oils.
Lots of metal plus carbon is conductive.
Same time become a resistor.
The porcelain covered with carbon and metals ground high voltage
Electrodes may look nice and spark plugs no good or not efficient.
The best Spark plugs are with copper or silver electrodes.
Needs more frequently replace them.
