I'm tuned with BM3 Stage 1 - E30, v2.4.
Is anyone running aftermarket plugs? For my past 335i, tune and ethanol fuel i'd always run NGK plugs with a smaller gap to avoid misfiring. So far no issues, but I wonder if it would benefit and help keep timing more consistent across cylinders.

I have for my M5, went with ngk cold plugs and gap at .020
Oh, I also talked to Troy Jeup and his recommendations are to change the thermostat and use 5w-50 for oil. |

He rebuilds a lot of E60 M5, I was going to have him build me a 4.6L for my F10 M5.

Same lol, 10.80@127 and 10.87@127mph full tank here on 21s
60-130 8.10s on 2.3 Going to update to 2.4 its even better i hear Quote:
It is recommended at the moment to stick to OEM plugs, I've actually seen a lot of cars under-performing with NGK 97506 (Most Popular Fxx series plug) when used in B58 engines. Road smoothness (or if you have traction on it will just cut power at times it notices slip), If you're hitting bumps this will cause it too. Most importantly is Fuel Quality

Bump to hear any updates. Anyone change out the plugs on tuned X3 for any benefits?

Mission Performance said I can just re-gap (to .024") my existing plugs (should be NGK stock) in the 2020 X4M I have ~13K miles on them for the MP e50 tune. I just bought their e50 tune today.
I am going to re-gap the plugs (will grab model number in the process) and leave my BM3 e30 OTS tune and see if anything is better (log wise), then will flash back to stock, then flash the new Mission Performance E50 tune. |

F97 & F98 - S58 - Removing and Installing Spark Plugs Guide
Spark plug install/removal guide since newtis is down. Reuploaded new version that isn't cut off. Attached.
It doesn't mention disconnecting the battery - I recommend doing that before you start (leave the doors unlocked, trunk open, and place a towel where the trunk latches just in case) as you unplug/plug in connectors as a part of the install - not just the coils.

For an X3MC that isn't tuned, what do you think is an ideal interval to change plugs at... ?
I'm still learning a lot about the new S58. The N55 in my E90 M-Sport has a BMW Stage 1 PPK installed from the dealer & the upgraded package came with a "change spark plugs every 45k" decal under the hood. Kind of as a dummy reminder, just in case I guess. LOL
