DIY: ROW Air Box mod

I bit the bullet and bought some new boxes from a member. If using an SDS to reset adaptations won't correct it, I'm not sure what else will.

Well when you buy the ROW Airboxes most place include new MAF sensors. Maybe if you do this mod you just need the new sensors??

google "turbulent air across maf causing lean code".
Also I did notice with the charcoal filters out going uphill the engine would have this stutter...went away when I put the charcoal filters back.
I do run the AFE filters already, I guess that's good enough for extra airflow.

Plan is to replace with OEM unmodified boxes or purchase ROW boxes.
Here is my airbox when I removed my lids after I got fed up of the dead spots in my fueling map at throttle tip in. I also have a tune, so no check engine light, but honestly no tune can compensate for the inability to measure the incoming air. the sensor itself is faced the wrong way to work with cutting the trumpet off. If the sensor was further downstream we would have zero issues as all air incoming from cutting of the trumpet will be metered.
i did just take out the carbon filter and every once in a while, i throw a code for it. (mostly in winter (hey, surprise more dense air!)) perhaps the sensor that's in the US version cannot handle the mass of air. makes sense. if it can barely handle it, then anything else is foolish. if you need the few HP (2%??!) , just buy it from FCP Mercedes Air Filter Cover - Genuine Mercedes 1560940306 | FCP Euro. that includes the MAF.
personally, i don't think i felt and seat of the pants difference. besides the occasional code, and the anguish that that causes in the background, there is a change in intake noise. you can really hear the difference.
