Just saw these on my daily browsing of aftermarket parts for the Beast. Not sure if this is old news or not.

cheesy

Did not see these around a month ago, pretty sure theyre new

Johnny912

pretty cheap too and new Maf sensors at nice to have laying around.

Good find...I'm pretty sure these weren't on their site a few days ago. I wonder how much hp gains someone should expect with these on a blower? It says 5-10 hp increase on the site. Any input guys?

Weistec

We just added them guys. We saw noticeable gains and much better driving characteristics with the ROW boxes (this might be old news) especially with our supercharger system, so we decided to offer them at a reasonable price. Let us know how we can assist. Thanks!

I just may have to get me a set of these.

I ran the ROW airboxes on my CLK BS(before converting to an entirely custom intake system) and still run them on my C BS(which makes 790whp ). If they did not work they would not be on my car, PERIOD! The ROW boxes are an upgrade I recommend for any M156 motor NA or supercharged, it's some of the least expensive bolt-on hp you will find for these cars. These ROW boxes can be difficult to find from time to time so if Weistec is stocking them I would jump on it fast.

Lol good sales pitch Jim...I bet you can sell me ICE in Alaska as well. all jokes aside I agree with you and thanks for your input. It's definitely worth it especially for the price.

jrcart

LOL, I am going to hit them up and tell them I want commision on all the ROWs they sell

In all seriousness, I was just chiming in because I have personal experience running these on both NA and FI applications. My experience with the ROW boxes dates back longer than my relationship with Weistec. I think I was the first person running ROW boxes in the US, evosport secured me a set of them from Europe very early on. I was running them back in 2008 on my CLK BS when it was NA, long before I was working with Weistec. They are a proven mod and for just $450 it's the least expensive 10whp you are going to find for these cars. In Weistec's defense they simply would not be selling them on their site if they did not make proven power.

If I run these would i get a CEL? When i remove the charcoals i get a CEL.

This is great. Hopefully someone can compare these with US version on the dyno

anthonymckay

Can't you also just modify a US airbox and get the same effect?... lol

Weistec

How did that work out?

roadtalontsi

hahahahaha.
nothing like a little turbulence for the mass air flow sensor to try and read.

anthonymckay

That's not mine. It's from a blog post on OE Tuning's website with a dynograph. Looks like it worked out about the same as the ROW airbox based on the data.

May be ordering these soon!

I've had these for like 2 months now..they are great it comes with MAFs too

estrellajon

Any CELs on these?

RNS-11Z

Do Australian c63 come with row?

mr747

we have them standard H

zibby43

I would think so but you can pop the hood and check.

ruey220

is the actual diameter of the neck on the ROW boxes bigger than the US version? Has anyone flow tested to see if they scientifically flow more, or is it all just based on common sense appearance?

+1

I can't comment on the CEL thing because my car throws a CEL even with 100% bone stock parts and is stuck on perma CEL but im going to say no the ROW's won't show CEL

crazy1eye

I installed them on my 2010 with stock filters & tune, no cel. I now have AFE pro dry filters in but I also have a Eurocharged V4 tune & still no cel.
