Not interested. Not a factor. Don’t want ANYONE touching my car but me, much less the dealer.

Ditto, I stay out of dealerships and even live with minor "glitches" rather than taking it in for warranty work. Had such poor luck in the past that (IMO) most times the cure is worse than the cause!

My dealer wasn't capable of installing the splitter correctly (even after 2 trues). I can't imagine them trying to torque the oil filter much less anything else.

I was at my dealer the morning after my car arrived and I wouldn't let them touch the car (other than the mandatory pre-delivery inspection & fluid checks). I did the original wash/detail and installed the splitter myself!
