I never bothered replacing with OEM like for like stuff.
I always buy Mann or Mahle regardless of what was in the car, they are used in supercars for a reason.
I like bosch stuff, but never use their filters in my car, but thats just personal.
I stand to be corrected but I think the terminology around warranty safe servicing is “OEM or equivalent” parts should be used. And unless you’re on super high mileages I can’t see your needing to change plugs, discs and pads in the original warranty period.
