Plugs and coils, or just plugs?

I have 70k miles on my 2013 F10 M5. The plugs were changed (based on Carfax) at 26k miles. The car is running fine (no misfires) in all regards but I'm planning to change the plugs to stay ahead of any problems and they are due.

I have an indy shop that will replace the coils as well with no additional labor charge. FCP Euro is running a special until 1/7 with 19% off, so I can save some money buying the parts now.

I've read many posts about replacing coils. Some posters say no need to replace the coils unless there's a problem. But I'm wondering since I can save a bit by buying coils and plugs now, and not have to pay extra to have the coils installed, it might be a good idea.

This might be a matter of whether or not I feel like spending an extra $185 to replace the coils. Or is there a mechanical/technical reason why I should replace both the plugs and coils together?

Given the infrequency with which both plugs and coils are replaced, I'm thinking to just go ahead and have both replaced.

Or an I missing something? Thanks for your opinions.

Buy genuine coils only and replace them

I had 2 bmws prior that ended up at dealer at inconvenient times due to coils going bad after that many km

Good enough for me. I'll change the plugs and coils.

Thanks!

I went stage 2 and got a drive train malfunction. I was also around 73k miles. After researching many sites I too was stuck with your question.

I ended up buying 1 coil and after moving the original coils around and changing the plugs, I ended up not needing the extra coil. If money wasn't an issue, I'd do both though.

That's my plan. With sale pricing on the coils and no additional charge to install them, it seems worth it.

Just replaced all my spark plugs and coils due to a misfire in cylinder 6 and DT error. Went with NGK spark plugs, Bosch coils, mission Performance stage 2 tune and gapped my spark plugs to 0.022... all is well

Planning to change plugs and coils. Just for peace of mind. Better now then being sorry about it later with a DTMAL. Good luck to you bud! Should be an easy job if you're doing it on your own. 😁
