I don't think the North American box tops are meant to be a restriction. They have to fit carbon filters on top of the regular air filters. The carbon filters seat behind a lattice. And when you stack that carbon filter in the box top, there probably isn't enough room for the cutout of the black, oval ROW air inlets.

[QUOTE=SonnyakaPig;4922877]I can see how opening up restriction at any point would be a good thing. It's an interesting question.

I would think opening up the front inlets and replaceing the boxes with RT boxes would be a great setup. But, then you still have the same size straight piping connecting the front to the back.[/QUOTE

Idk I just havnt seen a design in my opinion that would actually do something there are a few good ideas ie rt grouppe m, they all need to be put together and then still there are bottle necks

DuaneC63

Could you post a link on were you got them?

I purchased them from

http://shop.auto-bendig.de/catalog/

PNs are as follows:
LT side A1560940306
RT side A1560940406

Did some measurements... The funnel inside the NA box is 1.5" wide.... The ROW boxes are 2.75" wide.

The modified funnel inside the NA box to accommodate the carbon filter really restricts airflow.

IMHO I think Mercedes designed the air box perfectly for ROW applications. The NA version was a hack job/after thought to satisfy the NA market.

I'll let you guys know seat of pants feel tomorrow when I drive it.

So what is the cost for 2 shipped to the US?

Interesting...I'd be happy to install these just for the sound improvements alone. The thought of making this car sound even better is worth the price of admission for me!

Rsquad911

Well after driving it all day from SOP feel I notice a difference in the mid range. Pulls a little harder then usual.

I'm happy just for the sound and $$$ savings over a Gruppe M and Carbonio intake.

So these eliminate the use of the charcoal filters--has anyone thrown codes for charcoal delete?? I thought I remember someone having issues and they reinstalled the charcoals and it went away. Am I on crack?

Also, does anyone know if AMG would have made any other adjustments (ecu?) to accommodate our ****ty air boxes and charcoal filters?

I'd love to know how much better it sounds.
Anyone have before and after vids?

Ugly orange DOT lens, ****ty air boxes and no LSD fin cooler--maybe the ROW C63s are worth the extra $

No doubt and you can add the 19 inch wheels, we should start some kind of list of all the differences between a Euro spec and a U.S. spec C63.

What about aftermarket intakes, such as Renntechs CF one? How big are those funnels?

Rsquad911

The front inlets before the boxes were designed for the ROW boxes.

Hence the restriction with the US boxes.

Plus there hasn't been any proven data that shows the restriction is in the front inlets.

Once you match the front with the air boxes they were designed to mate with you get back the factory designed flow. Getting more flow vs the stock North American setup.

The rest of the world gets the "Original" setup.... We get a restrictive modification to get our car to market..

Here`s another members dyno sheet....
With Stock boxes charcoal/carbon removed (RED) vs ROW boxes (BLUE)

For comparison the member`s car made 359HP with stock US air box and charcoal filters intact.

Idk how much stock I would put in a dyno sheet that shows a difference of 4 hp you can get tgat type of variation between your first and second run on a dyno

It's the torque that matters.

HP sells cars... Torque wins races =O)

Based on looks alone, the Renntech looks to be superior. Smooth transition from box top to runner into the manifold. There is another member here that actually has some data showing it works at the track.

O is that how it works, well I guess you have it all figured out how to get this car to win races..

Rsquad911

[QUOTE=dodger63;4925810]Yup!

Rsquad911

Renntech obviously doesn't think the funnels are a restriction...

The factory funnels are used with this.

They say that this thing really does make a difference.



For cost vs performance/sound, I'd say the ROW boxes are your best bet. You can get about 6 sets for the price of the Renntech hahaha.

dodger63

keep digging actually the redesigned the whole front. I belive dadsc63 tested it for them if you want to talk the truth here. It's not my first run at testing all these intakes trust me, I'm glad your happy with your purchase,

JohnnyUte

It better make a difference for what you pay for Renntech. It's really hard to tell without actually running several dynos on each setup.

Got a whole bunch of PMs for video/sound clips....

So here they are...

For theses interested I posted a DIY ROW-style air box mod:

Do you have to disconnecting your battery when you swap out the ROW air box? My ROW air box come with new map sensors and do not want to pop that stupid "check engine light". On my 07 GTI, every time i disconnected the map sensor, the CEL on and i have to clear the code. Please let me know, thank you.

DuaneC63

They are plug and play. No need to disconnect battery. No CEL.

Anyone know if this is available yet? This is what I've been looking for...
