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 High Flow Air Filters is recommended.

  • Adds 5-10 Horsepower
