About to perform several service items and would like your opinions for the best performing parts. What would the dealer install?

Air Intake Filters: Mann/K&N/AFE/Mahle/Hastins
Fleece Oil Filter: Mann/K&N/BOSCH/Mahle/Hastins
Spark Plugs: BOSCH/AC Delco/NGK

Do Autozone/O'Reily type stores sell Mobil 1 Synthetic oil?

Thanks!!

 

I am not a dealer and I don't portray one on T.V. but I can bet that M-B dealers do not push American branded parts. Hastings, K&N and Autolite are all "out". I have used the Evotop fleece filter from Mann twice. No problems. I would bet that NGK is not their first choice either. If I was putting plugs in my Nissan- definitely. Bosch would be my choice for the Mercedes. I have always wondered how much money is squandered on "brand" affinity but I am too chicken to find out. I think Mahle is a factory supplier but they are not as popular as Mann in the US parts houses

 

If I'm not mistaken...

Plugs are Bosch, takes 12

Bosch# FR-8-DPP-33

Yes Autozone and O'reillys have Mobil 1, you need 0w-40
