Today I'm installing (and reviewing) a set of NGK spark plugs and Dinan ignition coils for my 2017 M3. This is my first time replacing spark plugs, so I wanted to make a sort of ride-along video for other first timers who want to start doing their own maintenance.
Other than the chore of everything you have to remove in the S55 engine bay to get to the spark plugs, changing them was pretty easy (and ignition coils are insanely easy). Much like any other maintenance task you've never done before, I was a little nervous to do this but I took my time and tried to stay organized which made everything go smoothly.
I'm not sure if it's power of suggestion or placebo effect (not sure that's applicable here) but the car feels a little bit better now. Little bit better throttle response, feels like she runs a bit more smoothly, one or two very subtle noises I was hearing before that I'm not hearing now so overall I'm super happy with the results.
I did notice a misfire on cold start afterwards (using BimmerLink), none at idle, and then a few very sporadic ones while driving. Based on what I've read, these can be expected, but I'm keeping an eye on them and will also compare again after I tune the car. I wish I would have scanned for them before hand to see if there was any difference but based on how the car actually feels, I'm not concerned.
Anyway, to any other first timer out there, this wasn't hard just time consuming. Save yourself some money and get to know your car better!
