Looking into getting a local mechanic to change the parts required by the service manual, BUT I've heard MB is anal about stuff like filters/spark plugs.

If I have to buy those separately it's not that much cheaper than just going to the dealer.

Dunno about M-B being "anal" but OEM parts and your smart Center can be costly.

It's just a car - normal consumables like aftermarket filters and spark plugs can be sourced and installed elsewhere often at a friendlier price.

It's more for to keep the warranty.

A set of replacement spark plugs is $70! Though it says optional by the dealer, I don't know if it's optional to keep the warranty?

No warranty issues, per the Magnuson Moss Warranty Act: https://www.sema.org/sema-enews/2011/01/ftc-validates-right-to-install-aftermarket-parts

If you have a 451 the spark plugs are under $40 .....

They can only void the warranty for the part you replaced with an aftermarket part. So like, if you replaced an OEM wheel bearing with a generic one and it fails, don't expect them to pick up the bill.

Otherwise, they can't void your warranty for working on your own car. Thankfully John Deere-type laws haven't hit the automotive universe just yet.

More plugs, less cost...
