Hey there community, I'm just wondering if anyone has anything positive or negative to say about the aftermarket options for an intake manifold on a W204 3.0L.

I'm seeing brands like SKP, Hella, and Pierburg in the $550-range, and then several in the $200-300 range. Any advice or personal experience is helpful.

Also, if anyone has done this replacement themselves, any tips or trouble you ran into is also helpful. I intend to replace the mass airflow sensor while I'm elbow-deep in there.

Thanks!!

I would go with Pierburg or Hella. Pierburg is the genuine parts supplier for Daimler and Hella makes quality parts.

what are the signs of manifold issues?

The dealer. I've also got a bit of a loud idle/acceleration note - the car sounds more "rumbly" than it should. I'm a little skeptical because I know the Mass Airflow Sensor is often a problem, and my scanner is showing a rich fuel mixture (a tell-tale sign the MAS needs to be cleaned or replaced).

The explanation that my dealership/MBtech gave me was damage to the small plastic arms internal to the intake manifold. Hopefully, they weren't trying to hose me.
