BMW E46 M3 Spark Plug & Ignition Coil Replacement DIY (2001-2006 BMW S54 Ignition Service)

►A BMW E46 M3's spark plugs and ignition coils are under constant stress during engine operation. The S54 engine uses high compression and revs high, putting enough stress on the ignition system that the service interval is less than your standard 3-series engine. Early signs of worn ignition components can be a misfire or a reduction in fuel economy. However, other faults can cause those symptoms, so ignition faults can be tricky to diagnose. We usually recommend an ignition service immediately if there's no information about when they were last changed.
More extreme symptoms of failing coils and plugs are reduced power, hard starting, and power breakup in the higher RPMs. If you're experiencing any of those issues, we recommend performing an ignition service. At the very least, you'll know you have new parts installed and a Lifetime Replacement Guarantee to back them up.
In this DIY, FCP Euro's Professional DIY'er, Mike Hidalgo, takes you through an ignition coil and spark plug replacement on a BMW E46 M3.

[@rogerreyes4694]

[@miketurpen4738]

Great video. I’m changing plugs on my 2008 Z4M and will follow along with this video.

[@fcpeuro]

Love to hear it, thank you for wrenching with us!

[@MeeMoo220]

Thanks for making this video man. I just replaced my own plugs and coils an saved over $1500 from what local shops were charging. FCP Euro is the best!

[@509ryan]

Did you have to gap the spark plugs?

[@MeeMoo220]

@@509ryan They usually come pre-gapped these days, but doesn't hurt to check the gap and adjust as necessary.

[@509ryan]

@@MeeMoo220 cheers, just finished the job few hours ago. No more misfire 👌

[@MeeMoo220]

@@509ryan nice man. Congrats! My alternator died on my celebratory drive afterwards. Hopefully you have better luck. Haha.

[@kishan813]

Thanks for this! More S54 content please! Valve lash adjustment, perhaps? 🙏

[@GimliTehDwarf]

Loving this S54 content. Made my order my coils and plugs through you guys and just go them today! Going to do it tonight

[@fcpeuro]

Thank you for wrenching with us; cheers!

Great video. Thank you

More to come!

Thank !!! so detailed !!

Please do a video on replacing spark plugs and ignition coils on the 2.0 supercharged and turbocharged four cylinder engine on the 2017 VOLVO XC60

[@johnnyblue4799]

Very easy job indeed. Great blowing out the debris around the spark plugs. On my old car the plastic tube around the ignition coil wires was so old and cracked that there were plastic bits everywhere, so a bit of compressed air goes a long way.
Well, all good except that I really wanted to hear that engine running. That was not nice, not to start it.

[@Daniel-1-1-1]

Lol I just did mine yesterday and without pulling out the Cabin air filter at all…just used shorter flex extensions and was able to get it done.

[@Kiss__Kiss]

NFS Most Wanted lol E46 M3 Let's Gooo, Mike!!!

[@ThommMcEachryn]

I liked the time lapse bits vs watching removing bolts/nuts click by click of a ratchet..

[@cb400fhonda6]

Good details
Xcellent job

[@fcpeuro]

Thank you! Cheers!

[@canes415]

Awesome details on these DIY's! When will the valve adjustment for E46 M3 video be coming?

[@fcpeuro]

Working on it!

[@martsmarts]

I noticed my ignition coils come as screwed. And the mechanism is far different. Are they interchangeable?

[@TnGearhead]

For 16mm sparks it is 32nm

[@UhhhhhnooOOo00oO]

Or 2000 dollars for a W212 replacement. Labor and dealerships are fun.

[@patricksimmons5563]

How long does the job take?

[@ARKXR1]

Did you mean 16mm 12 point socket? You said 16 point 12 mm socket.

[@davidmusiyenko4158]

Hey guys! I’m putting in a request for all the b9 S4/s5/SQ5 content please! We need it!
