Product Description



From the factory, Mercedes AMG vehicles with the US Spec M156 engine are equipped with a mass air flow sensor housing that has a restrictive profile. Non US Spec M156 airboxes, commonly nicknamed ROW Airboxes (Rest of the World) are manufactured with a much higher flowing mass air flow sensor housing profile.

Installation is quick and simple as the ROW Airboxes are a direct replacement for the factory US spec airboxes. Upon starting the engine it will be apparent that the engine is breathing more freely as it will have a more aggressive sound note, better throttle response, and improved power band.

Vehicles with a Stage 1 or Stage 2 M156 Supercharger System greatly benefit from the improved flow characteristics of the ROW Airboxes. For Stage 3 systems, the ROW Airboxes are a requirement.

The ROW Airboxes come in a set of two, both left and right sides, and include brand new mass air flow sensors.

For maximum results, the combination of our M156 ECU Upgrade and M156 High Flow Air Filters is recommended.

Key Features:

  • Adds 5-10 Horsepower

  • Increased Flow Area

  • Amplifies performance of your Weistec Supercharger or ECU Tune

  • Set of 2

  • Includes New MAF Sensors
