Hey, you made this video 4 years ago but have saved people a lot of money. Kudos to you my man! I just replaced mine using your detailed video. Thank you!

I tackled this myself after watching your video. Thanks for saving me the cost of having to pay someone to do it. Thanks again.

[@insidedadshead9691]

I don’t believe I’ve ever changed spark plugs as easily as these changed. Amazingly simple.

[@peterhutchinson9063]

A tip when replacing the left and right air tubes is Mark a line with a black eraser to know exactly where it's aligned to fit perfectly.

[@joejohnson3396]

Thanks for this man you saved me $1200

joe johnson you're welcome!! Glad I could help!! Have a Blessed day!!! Enjoy your benz!

Thanks man. Very kind of you to show us.

Mercedes says DO NOT use any kind of anti-seize on spark plugs

[@carrilloscleaning5402]

Great video and Explanation thank you!! make my job easy..

[@lorenreyes2855]

Great Video Sir! Very Much appreciated! Thank you for sharing your experience and knowledge!😉

[@bimmermodz1364]

Great Video! I would just recommend unplugging battery underneath the hood first as the car is still grounded. Metal on metal contact can create a spark or even worse, a short.

[@stephencannon3140]

AutoZone sells a socket that has a dedicated extension built into the body. The advantage of this design is you don’t have to worry about the extension coming out during renovator installation. This also has a small magnet in the body that keeps the plug from falling out of the socket and either getting stuck or worse the electrode tip breaking off and falling into the cylinder causing pretty certain engine damage. Extension has a limited range ball joint which allows some angling of the socket. This design does work and should help for the removal of the rear bank of plugs on front wheel drive vehicles. I mention AutoZone but also see them on Amazon with either a 6 or 10” extension bar. The socket is built into the design so no changing socket sizes for multiple diameter plugs. I have three vehicles two current and another previous that all used the same size plug so I definitely am getting my money’s worth out of it. I say dedicated spark plug but you could use it for pretty much any bolt that would require a 5/8” deep well socket.

[@jonathanjimmeson]

Anybody have a video for the valve cover gaskets for this thing ?

[@deruin78]

I wish my S600 was like that

[@selvansakthi5404]

Thanks

[@insidedadshead9691]

Literally the easiest car I have ever changed plugs on.

I can’t believe it’s that simple. You can see and reach them.

I have a 2008 s63 amg i was wondering if i change the spark plugs would thats make the car quicker

[@mikee6220]

xx battl3_born maybe restore performance but not increase

[@neilw8221]

Thanks for sharing. I’d like get your take on extended warranty on this thing. I picked up a 2013 s550 with 52000km on it at the moment. The car is in great shape. I’ve been wondering if I should keep this exclusion warranty that covers next 3 years/50k for around $3500 with $200 deductible. Yes, I can do the basic maintenance stuff myself or with help from my mechanic friends. And I know there’s no one answer for all on this. I’m inclined to save that money and get a diagnostic tool. By the way, I tend to only drive less than 10k km a year. Would love to hear your thoughts! Thanks!

[@mikee6220]

Neil Wang in short don’t get it. The car is a baby and even with repairs $3500 goes along way. Just make sure the air suspension is in good shape and the transmission fluid has been changed, and it has solid service records

[@neilw8221]

Mike Neely, appreciate your thought and the speedy response! Even though you are probably 1 out of 10 to say no to the warranty, but you got me convinced. Lol. I think I’m going to take my chances. Cheers

[@tsrwakemaster]

If you had the ABC suspension or 4-matic I’d say get it

[@AD-ql7ww]

Thanks for a great tutorial! Did you get an error that caused you to change it? If so, what was the code? Did you end up changing all of them? Thanks in advance.

[@mikee6220]

A. Daniloff no error code. Just changed them as part of preventative maintenance

[@stephencannon3140]

I have seen videos with some Mercedes V6 and V8 engines with two spark plugs per cylinder. What years and models were they?

[@Michael-rr2ms]

I think that was the previous generation w220

[@oldsaurora4674]

Engines M112 and M113 from 1997 until 2012 in different models.

[@francoorozco3662]

Is this done the same way on a V12 2007 Mercedes S600?

[@George-cb5rg]

Infinitely more complicated on S600. Two spark plugs per cylinder (24 total), plus ignition coils come in 2 sets of 12 coils, very hard to pull them out simultaneously. If you don't do it right you damage the coils and pay about $1000 for a new set ($2000 if you damage both sets).

[@brianbui2460]

If your changing out the coils as well do you have to reset anything like the computer?

[@Aslan-tubenl]

No

[@undersan32]

Hey Mr. Loud, my #3 ignition coil is bad. Do you know how I can tell which one is #3? My scanner had the code P0353. When I looked it up on google it said that that is the code for the 3rd ignition coil. Any hel you can give it would be greatly appreciated.

[@Velo1010]

Do the spark plugs from the dealership or online Mercedes retailer come gapped correctly?

[@spat726]

good question

[@daniellucatero-jimenez.1440]

The ones from autozone come pregapped already.

[@ratoi233]

I need to replace ignition coil B on my 2007 S550. Do i need to unplug the battery first? Is unplugging the batter going to cause any problems with the computer system? It seems like this is the procedure I should follow for the ignition coil replacement.

[@mikee6220]

Yes always unplug battery as a safety precaution.

[@shawnthomas397]

I thought you was going to show it how to unhook the coil pack that's most people are nervous about I'm hooking that wire off the coil pack not so much of the spark plug//

[@Velo1010]

What are the torque specs for the coil pack screws and spark plugs?

[@alexvassiliou8097]

Should be in the “technical data” section of your owners manual.

[@Aslan-tubenl]

Normally it says on the package of the sparkplug. Some 24NM some 17NM. The torque spec for the coil pack is about 10NM

[@sonnydhillon7273]

Mercedes wants $600 to change the plugs!! Thanks for this video - you just saved me lots of money. Question - shouldn't they have changed the plugs when they did the A5 service?

[@mikee6220]

Sonny Dhillon to be honest I don't know what they should have done. I love Mercedes I just hate the dealerships and techs. $600 is a joke. Guys never forget!!! A Mercedes is still just a car with four wheels. Don't let anyone upscale you! Because that's a load of BS!!

[@mazensholakh9529]

What did you gap the plugs at ?

[@mrtracy123]

They are pre=gapped

[@sputnik8407]

Do you prefer this engine or the one that replaced it ??

[@mikee6220]

sputnik this one. Prefer naturally aspirated anyway!

[@Duke-ih8mo]

Gm do i need to discount the battery

[@Michael-rr2ms]

Chittychittybangbang! Always disconnect the battery when working in the engine compartment

[@aptmob771]

Will bad spark plug make car shake and lose power?

[@Roderick_YT1]

Yessir

[@danielfavors2613]

Yes, this happened to me today.2/28/2024

[@marvinknight]

Won't unplugging the battery cause the computer to reset?

[@mikee6220]

Marvin Knight there's two batteries one for accessories and one for the engine.

[@marvinknight]

Mike Neely correct, so which one should I disconnect?

[@mikee6220]

Marvin Knight the one underneath the hood
