If you don't care about carbon looks you can make the same power with row boxes and ml63 y pipe.

MAF sensors were on the outside of V1. V1 was less bulbous. The one listed is V2.

Kriston

Tested that, makes nothing. ROW's make little to nothing, only box that actually made power was the Renntech box.

I tested them and gained airflow while logging but also had headers and 82mm tbs. Did you try the bigger y pipe?

Kriston

Did this several years ago at EC Canada. It was a waste of time. The Row's are sketchy too. These airboxes don't make much power at all, but the Renntech made almost 10 WHP on the dyno same day. Look for my original post years ago, i posted the graphs.

I have renntech TB's and long tubes as well.

I had complete opposite on the y pipe and picked up 2 mph. You sure you tried the y pipe because I was the first one to do it. Any pics of it on your car?

Its a huge difference in size vs stock pipe.

Kriston

This was done 5-6 years ago.

Every photo in this thread (3) and the photo in the eBay listing shows differences in design. So much for only 2 versions.

So...you didn't try the larger Y-Pipe?

E55 Bulldog

I want this look under my hood and ill take the added power as well.

Kriston

So you didnt read my post?

HLG600

I did, and found it vague. So please clarify if your testing covered the specific combination of ROW airbox lids and the early M156 Y-Pipe.

Search my old posts and you will find the answers you seek.

Respectfully, instructing to search through old posts rather than answering a simple Yes/No question is a bit silly, especially when that question is directed at something you claimed.

Here was my setup and is really close to the renntech setup for alot less money.

AKnight55

picked up a RennTech box a few months ago on Facebook marketplace of all places for $1,500. They are definitely rare to find on the used market for a decent price.

Yea these also look different than the one listed on eBay. I messaged the seller asking him for a deal and he wasn’t budging at all. If Kriston is saying both iterations of the designs basically function the exact same, it really Makes me want this intake more but seller is being a little uptight.
