Hello all, first time poster long time lurker!

My 1999 C230 Kompressor is having some hesitation issues (I've done searching) with codes for misfiring (codes P0300, P0301, P0170).

Anyways I changed out to a new Bosch MAF (Part #: BOS-0280217114), still same issue. So now I'll change my plugs and coils.

My question is which coils do I buy? Are the Bosch ones okay?

Bosch BOS-0221506002

or

Mercedes MER-0001587503
https://www.fcpeuro.com/products/mer...mer-0001587503


So I'll be picking up
- 4 Bosch plugs

- 2 Coils whichever you recommend

I may as well change out the wire set as well. Is this plug wire set okay? I see it's made by STI, but I can't find any Mercedes or Bosch specific ones.

Any help is greatly appreciated thanks guys.

cant comment on the sti, but those coils look identical to me

So like I said, at first I tried the MAF, but still same issue was there (nice to have a spare Bosch MAF now)

I changed all 4 plugs, two Bosch coils and used the above STI wiring kit and the problem is gone.

The car has never run any better. It really is amazing a car from 1999 feels this great to drive.
