This do it yourself video shows how to replace spark plugs on 2005 BMW M3. This procedure is pretty much the same on all 3 series e46 chassis. The spark plug…

fantastic DIY, I changed my coils and sparks thanks to this vid – really appreciate the high quality editing, thank you!!
Great DIY, awesome job man, changed mine with no problem
lol 30 minute beer break – that’s funny. However to do a spark plug job in 10 minutes, that will be pretty rushing even on e30 and I’d challange you to post a link to your “unedited” video of doing the same job alone on e46 M3 in 10 min. 🙂
and if you dont take all 30 minutes for beer break… its only takes 10min
)) Страно, даже монтажка не пригодилась)))
Thank you for the tutorial. I just got my m3 e46 as well. Will do this soon. Can you do one for the valve adjustment? Thanks
Thankyou, I needed to find out the torque required on the sparks.
Awesome video
Awesome video!
thank you for a great video… Awesome!!!
You are a very good mechanic, The reason BMW and other manufactures make it SO TOUGH to do DIY on there cars is because…THEY DO NOT want just any Tom Dick or Harry playing with the engine. This job would have taken 2 Minutes on a MK 1 Ford Escort (1968-1974)
Thanks for the comments guys! Glad this is helpful!
BTW… thanks very much for taking the time to do this video. It was a big help to me.
I have a 530 XI sport wagon that I used the plug removal information for. I had figured out how to get the power plug removed by lifting the tab, but the boot was stuck so well I thought that just pulling it out wasn’t the way it worked. I hate forcing things. What I did once I saw this was put a terry rag through the tab hole and grab one side of the rag with each hand and pulled straight up. They all popped right out! And I didn’t have to worry about cutting myself. FYI!
Top video thanks alot!
Thanks for posting great video I am confident I can do it in no time.
hows has the car been to you ? im planing on buying a 2002 M3
WELL DONE
Awesome video, I will be changing my spark plugs and coils this weekend.
Thank you! Enjoy.
Thanks for the comment… There is really nothing to it. You can do it in 30-40 min on a nice sunny day…
Sorry man, your comment just doesn’t make any sense to me. Now you are talking about wear and tear on the threads which if torqued correctly can outlive your car even if you were doing the maintenance every month… Also, there are great number of spark plugs that you don’t need to adjust gap as a service, because of the type of electrode used. It sounds to me you like your cars to break before you would touch anything on it. You sure can break new plugs on install same as you can break a hammer
Great video. Thanks for posting. Very helpful
Great video, very detailed and makes it easy to do! But after watching it i rather pay my mechanic 100 bucks for the trouble. One of the best DIYs out there!
Trouble is that every time you remove a spark plug you are wearing/damaging the threads in the head. Of course it doesn’t matter whether the plugs are being removed for cleaning/adjustment or replacement, it’s still wear and tear on the cylinder head. I would simply suggest the interval be extended as long as possible while the plugs are maintaining their gaps (set at minimum, let them wear to maximum gap). Preventative maintenance is no guarantee because new plugs can fail on installation too.
I would say if you don’t see the need for replacing spark plugs after 33 years of maintaining cars and bikes, I would not be able nor should try to convince you of what and why. Your analogy of incandescent bulb is not the best one for good maintenance of a car. Spark plugs are definitely not one of the “run-to-failure” maintenance items and should be a part of preventative maintenance. You can use this video to see how one would access the spark plugs to clean them and set the gap.
On what basis did you decide the plugs were worn out? The new plugs will look just the same as the old plugs after a couple of days use. In 33 years of maintaining cars and bikes, I have never found the need to replace spark plugs; clean ’em up, set the gap and put ’em back in. Sure, they do wear but if you can maintain the gap to specifications then replacing them is false economy (would you replace an incandescent lamp if it’s still working?). I may be misguided here but I don’t see the need.
Great video. Going to do mine in a couple of weeks. Thanks.
Great video. thanks for taking your time and explaining everything.
gracias from mexico
ok friend. thank you for feddback. nice car..that engine is the best sinphony ever. stay cool.
The E46 looks much more robust than the E36 IMHO. I would put in the Signature Motoring performance intake kit for only around $150 and gain up to 13HP on the stock output for the 330i and a bit less for the 325 and 328. I highly recommend this item, see my youtube channel for the action video on it.
-Installs in round 45min.
-Guaranteed HP increase
-Induction sound to die for
-Awesome fit/finish.
See my video of how it sounds AND performs!
Thanks for the comment. However, I don’t know what is GPL or auto gas system is. Not sure if it helps, but there are no aftermarket modifications made to the engine or related components/systems.
very educational video. can you tel me if you have the GPL(auto gas) sistem instaled?
THAKS.
Very informative, will watch again when it comes time to replace my spark plugs/ignition coils.
Gr8 VIdeo!
Great video! 2 Qs: While tightening the screws on the spark plug cover, my 10mm socket came off and fell into the front of the car, between the metal grilling and the fan. I couldn’t reach it but managed to pick it up with a wire hanger, but it fell into the engine pan or whatever that big piece of plastic is under the engine. Should I bother to get it out, and if so, HOW? BTW turned out my engine misfire was actually a bad ignition coil which I also replaced while I was there. Thank you!
How much did u buy the car for if u dont mind me asking?
Nice video ! Thank you ;)
I have 147,000 miles on my BMW 3 series with E46 engine, not an M3… I tried changing the spark plug with a small socket wrench and a 12 in extension and a 5/8th socket. BUT THE SPARK PLUGS seem to be stuck … What should I do to remove the spark plugs ?
Spacibo bolshoe!!! Just did my S54 M coupe today – great video.
I love my 328i. Only mod is a Signature Motoring performance intake kit. They run around $170 and add up to 9HP in the E46 323/325/328 and up to 13.9HP in the 330. That’s about $17/per extra HP… A good value for the extra oomph. General HP increases are shown:
E30 series: 6.0-13.4hp gain
E36 series: 5.5-12hp gain
E46 series: 6.0-13.9hp gain
E92 series: 8.5+ hp gain
Z3/Z4 (all): 5.5-13.9hp gain
