Was just about to change mine this weekend!

[@fockinausty]

I love your contents. Very informative and helpful for me to learn and prepare self-maintenance of my G42 M240i.

[@M3E92V8]

More DIY videos KEVIN this one is very informative

[@julienxdarrell]

Good timing, I was just looking up plugs to change

[@supremegt]

Got my new eldor coils and champion plugs around Christmas. This is next on the list #b58gang

[@thierryhimself2796]

Same as the other comment(s), it was planned for the weekend so couldn't have been a better time

[@nicholaslong3010]

Thanks Kern. Keep it coming.

[@brumorabia]

Right on time! But I'll go for the NGK iridium

[@thomasvennekens4137]

all hail to stock plugs and stock gaps :) (y)

[@dougcoffey3496]

Great vid as always! Have you done a video talking about tire and wheel setups? I know there’s endless options boiling down to personal preference, but to go through some common setups, the best for the stock wheels, and your personal setup would be pretty cool.

[@kern417]

Not yet but coming soon

[@magikmastr]

great video. Thank you!

[@danked6731]

Unreal bro

[@TeeZB58]

Okay so just to make sure I got it right and dont miss anything, whats the torque spec for the spark plugs? And what is proper plug gap for my gen 1 b58 tuned on MHD ots maps. Thanks for your content!!!

[@sharklos]

Hey Kern! I recently replaced my torn PCV diaphragm and my oil filter housing. I assume I should probably check spark plugs. Any other additional maintenance I should probably do? So far I've only changed the oil after the oil filter housing replacement bc of the coolant leak. Thanks brother.

[@VinnyMacVlogs]

Is the socket a 14mm or 16mm? I want to do this soon but kies Motorsports has 2 different ones when I type my car in the search box

[@kern417]

14mm 12 point socket

[@F32_Rocket]

FCP Euro sells them cheaper.

[@ajneely7251]

Should I still change my plugs to new ones even if the injector is stuck open? Or should I wait until I replace the injector and then change the spark plug?

[@lokisgr]

Hey man nice video as usual, im MHD stage 2+ with TU pump and I had regaped my plugs to .22 for the setup... should I return to stock? I'm on factory Champion plugs with 18k miles. Thanks!

[@kern417]

If it's running fine, I wouldn't worry about it. I just recommend stock gap for future plug changes.

[@lokisgr]

@@kern417 is there any downside to my gap at .22?

[@kern417]

Hello, my bmw G32 630i b48 has black smoke in the exhaust end, and with an obd tool, I found the mix ratio goes 0.9 around right after engine braking and slightly accelerating. In idling or just re-accelerating while running without engine brake, these have 1.0 ratio. And 1.0 at normal running and full acceleration. What do you think is wrong? The dealer says no problem if no diagnostic error in the display. In that condition, the intake pressure shows slightly lower than atm. pressure. I think the throttle is opening less in that case. Then the fuel injection accordong to the MAP should have been adjusted. very strange, I guess this is inherent in software itself. I am gping to replace the plugs first, because the car has 55K km milages

[@willm2624]

Does the depth of dark on threads indicate anything? I noticed some extended longer than others.

[@kern417]

Not really

[@zorantb]

How often do you change your ignition coils?

[@kern417]

When they fail

[@zorantb]

@@kern417 And usually misfires are one of the possible indicators of that? I ask because some forums mention changing coils at 100k or at 50k if tuned.

[@kern417]

Yes misfires in boost

[@avalaugh1980]

Hey Kern, what’s a good mileage to change out the plugs ? Got no issues and engine is only on 10,000miles. Stage 2+

[@kern417]

30-40k

[@avalaugh1980]

@@kern417 thanks for the reply

[@adriansanchez-tw5dn]

What about coil pack ? Are the eldor from fpc eruo oem quality?

[@AMS611]

Is there anywhere you can buy the clips for the coil connector? Brittle plastic broke last time I did the plugs and I hate having the possibility of it coming unplugged

[@kern417]

I'll have to find the link that somebody posted

Did you leave the foam out? How loud is the dorch stg2 hpfp in the cabin?

[@kern417]

Yes and it's not bad at all

[@JamesB58]

hey man i have a 2020 m340i and the ngk spark plugs i ordered are a .23 gap and im stock does this sound right this the one i got

[@kern417]

you ordered new oem plugs and the gap was 0.023 out of the box?

[@BadLTD]

How often should one change his spark plugs having a Gen1 B58 with TUPump and OTS tune Stage 2+?

[@kern417]

30-40k mi should be good

[@rogermcdowell8629]

Just ordered genuine bmw plugs for my m340i. 4 are champion and 2 are ngk. Does that matter? Same part#

[@kern417]

It's not ideal but it should be ok. They always do that. I recommend ordering parts direct to make sure you get 6 of the same ones

[@mohammadhasansalehi1799]

What shout I do if it is running lean on one spark plug

[@kern417]

check for boost/exhaust leaks in that area

[@jessemcdonald2315]

Do you index the plugs?

[@kern417]

No

[@TeamNoBrake]

What if you have oil on your spark plugs?

[@kern417]

probably pcv

[@jae8446]

What camber plates you got on the Kws?

[@kern417]

Millway

[@filsm140]

Question about the foam. Does the foam covering the back of the engine really matter? I thought maybe there were some insulating attributes to it as well. I've been contemplating to leave it or take it out. Sound wise having the engine cover on or off makes the most sound difference.

[@kern417]

It's mostly sound deadening. It's removed on both of my cars.

[@hondaman8648]

Not gonna lie, this is rather cringe. No anti seize or die electric.

[@kern417]

From the BMW manual: "Do not grease/oil thread or use any graphite or copper grease. Adhere to the torque values of the packaging information or regulation. Note: If these instructions are not followed, especially with regard to greasing, this may result in mechanical damage to the spark plug housing/thread. Spark plugs that are not tightened sufficiently lead to leaks and to the spark plugs coming loose during engine operation." So, you were saying?

[@hondaman8648]

@@kern417 common sense, dissimilar metals, use anti seize. You must not have ever been an actual mechanic

[@kern417]

@@hondaman8648 also common sense: BMW makes millions of vehicles a year with the same maintenance strategy and it works great. You must have never been an actual engineer

[@hondaman8648]

@kern417 no, I'm not an engineer x and thank God. The people that really understand cars and see engineering mistakes are the ones working on them. Steel plugs seize in aluminum. Fact.... but you do you, that's your car, not mine. But in the 100s of not thousands I've done, not one issue using anti seize.... plenty of issues dealing with plugs when it's not used, especially most factory ones.

[@kern417]

@@hondaman8648 engineers are the ones that make solutions like this possible. They understand that closing on 10 years of data trumps any assumption you make. But you're right, my car along with everyone else's working well and going fast. You can keep on wasting time with unnecessary steps 👍🏾
