DIY: ROW Air Box mod
I read a lot about the ROW Air Box Mod, but I couldn't find a good DIY, just a couple of pictures here and there. Based on that I took the jump and modded my stock air boxes and documented the process.
Keep in mind this can through a CEL if you are not tunned. You will need: - A Dremel with a cutting wheel - Exacto knife - Long neck pliers - Sand Paper 150-200 Optional: - MAF cleaner - Compressed air You start with your stock air box top: https://cimg1.ibsrv.net/gimg/www.mbw...f5285b8c1c.jpg Make sure you remove the MAF sensor: https://cimg2.ibsrv.net/gimg/www.mbw...6d2f5bac0d.jpg I just rip off the thin plastic lattice by hand: https://cimg3.ibsrv.net/gimg/www.mbw...6ccba9aa09.jpg With a Dremel I cut a superficial groove in the black plastic: https://cimg4.ibsrv.net/gimg/www.mbw...2897c98db1.jpg Close up of the groove: https://cimg5.ibsrv.net/gimg/www.mbw...b97302a0b9.jpg You now can easily separate and remove the plastic pieces: https://cimg6.ibsrv.net/gimg/www.mbw...23866ebbfd.jpg https://cimg7.ibsrv.net/gimg/www.mbw...6f57885aee.jpg Note: It may be possible to use a heat gun to melt the glue a remove the black plastic without breaking it, but I didn't try. With the Dremel cut the "trumpet": https://cimg8.ibsrv.net/gimg/www.mbw...18191c60a2.jpg Be careful to cut the trumpet but not dig in the metal parts around the MAF: https://cimg9.ibsrv.net/gimg/www.mbw...17211c99c6.jpg After cutting, quite rough: https://cimg0.ibsrv.net/gimg/www.mbw...bd6da6c99a.jpg Trim hard to reach sections with long neck pliers: https://cimg1.ibsrv.net/gimg/www.mbw...7700dd732b.jpg Trim the glue with an Exacto knife: https://cimg2.ibsrv.net/gimg/www.mbw...142f432167.jpg Sand the edges to remove the remaining glue and to smooth the rough cutting around the trumpet: https://cimg3.ibsrv.net/gimg/www.mbw...ca1542b9a4.jpg Clean the air Box with compressed air, then water then compressed air again, make sure there is absolutely no trace of dust or water, then reassemble the MAF sensor. While you are at it you can use some MAF cleaner to make sure the MAF is grease free. https://cimg4.ibsrv.net/gimg/www.mbw...952792da3a.jpg Behold your modded airbox: https://cimg5.ibsrv.net/gimg/www.mbw...21f3a1f791.jpg Hope this helps! |

The flat spot may not be optimal, but it still works better than not having a it at all. The maf especially takes advatange of this because it helps straighten the airflow.
https://mbworld.org/forums/attachmen...d-p1040833.jpg Also because there is a gap in the back I highly doubt that there are any velocity stack effect: https://mbworld.org/forums/members/t...box-mod-09.jpg Sure real ROW air boxes will be better, but for the price, can't beat it. |
I have known about this mod, and the velocity stack issue held me back.
To the OP. Most excellent write up. Kudos. |
skills!!!

Keep us posted on how she feels. I try not to second guess engineers though, at least often.

What is the price/part number for the ROW boxes?

y'all do know that you can send your factory boxes to bruce and send him some cash and he will send you back some air boxes done like this?

(of course all within a certain budget - otherwise we'd all be driving cars with gold plated engine parts) |

For some reasons the pics from the OP are gone, so here I repost with the pics.

Hmm.... That sure looks like it would allow more airflow. Real way to tell if you are getting more air would be to log MAP before and after.
How does it drive ? Any difference ? Still smooth ? |
I did this to my E63. Reset adaptations. No go. Lean faults at idle.
