If yours is stock, replacement OE ILFR6A NGKs will trot out all the ponies for which you’ve already paid.
Do avoid replacement plugs with less than the specified 26.5 mm/1.04 inch reach though.

He is correct but...
NGK's LFR7AIX has proven suitable in several members’ modified rides.

Bank 3 is hard to change so I would check there to see if the shop actually changed the plugs. If they are ***** to take out or the wire is too tight or the brand/imprinting on the plugs is different they most probably weren't changed.
I think you paid a silly amount for the change I think about $500 to six at a stealer is right and half that at a mb specialist indie.
I keep my own service records and do scheduled services at the dealer at a discount to keep up the warranty. If they do the reset that means they acknowledge the compliance, IMO.
Another way one can tell if the plugs were changed in a 5 yr engine if one or two are really hard to remove. Good practice is to use a dollop of antiseze on the plugs and a tad of dielectric grease on the
