ik ive looked around for the most part. But was wondering if the cold air intake from a crossfire and engine cover from a ml320 would work in our bays? It seems to be a good option for the crossfire guys so I was wondering if anyone on here has tried it out?

Glyn M Ruck

You already have a cold air intake.

03c320

Yea I know thst but the look of the ml320 engine cover and the cai from a crossfire looks way better so I was wondering if it would be do able in our engine bays

03c320

No one has ever tried this before?

Alswag

Sure, lets re-route our MAF, airbox, and get rid of our CAI for an intake that draws hot air.

In all seriousness, no. This will never be beneficial to a M112 with the updated airbox.

03c320

Why would I relocate any of that stuff? The airbox is just a cover there is now maf attached? And why would it be hptt air. Im not looking for huge prwformance gains but for more of ashtetic value. This is what im refering



too.

Alswag

That's a highly dangerous and unnecessary modification. There's no filter and you'd be sucking dirt directly into your cylinders. Not only that, but the aluminum (steel?) is highly heat conductive and will just evidently draw in hot air as it's not covered with anything heat resistant.

There's no point in doing that modification. There's no power to be gained, and it's more dangerous. Stick to your stock airbox.

Not only that, but that engine cover will not fit in your car without proper modification. The rubber grommets which hold your original airbox are not in the right position to secure the cover to the top of the engine.

Mmm, I do have to say that's sexy.

C32 people have done it. Would you be able to mimic what they've done? No idea if that would work or not, as unfortunately, I don't have either engine.

tommy

Al, they're in front of the red parts of the tubing. Entirely doable on that engine. No idea if it works on his engine, of course.

03c320

Yea its not dangerous obviously id have to move the filter back a few inches because that car has them they just sit behind grill on those and we do not have the space for it. I think it should be to hard to do and also I would probably wrap the intake in heat wrap to reduce heat sink. The engone cover fitting is probably the biggest obstacle.

tommy

Please excuse them. MB owners tend to be a bunch of old ladies afraid of change.

03c320

Lol. No harm done.

AzCamel

That's a nike kit but way too much money, almost no performance gain for $1k. The only negative I see is a bit of lag due to intake length but if you have a heat wrap on the intake tube you will should see temp drop when driving since the filters is right behind the grill.
It's your money.

I did an e55 air box set up in mines. Can't say if there are any power gains, but like how it looks over the c320 air box

Alswag

Ah, I didn't see them in the picture. Regardless, it's a pointless upgrade. If anything, hot air will be drawn because...

1. The filter is inside the engine bay, uncovered. Therefore it'll get hot and will just end up drawing hot air into the MAF.
2. The tubing is also uncovered, so if the filters won't draw hot air, the former will.

I mean it's your money dude, but it's not a good idea. Why make an aesthetic mod which pretty much only you (and/or your mechanic) will see, and that draws hot air into your cylinders? It's not worth it and I'd advise against it.

However, if you decide to make a CAI, use rubber, plastic, PVC, or metal tubing that's covered in thermal tape. You'd also have to find a way to cover your air filter the same way. Heck, I've seen people put filters inside of used coffee containers and it works pretty well. Unless you do it this way, you're not gaining anything, and even then it won't be any more efficient than stock.

tommy

The way that this should work is that there is a tube that is attached to the grille opening in the front of the car, this then goes to the filter (K&N cone or what have you), fully covering the filter's front (ie, no warm air from the bay directly contacts the filter's face or is drawn in), then the tubes take it to the tb. I would believe that would all be not visible in the attached pic. Of course, that's if it's designed properly. My PRM in my crx has that kind of design.

Another thing that's not being discussed here is that the path of this type of setup is more efficient than dumping air from a tube into a retangular airbox, then pushed through tubing from there. I have no idea what this increase in airflow efficiency nets you, but I'd hazard that it's at least sumthin.

We can discuss this further over beers when I'm at our Mississauga offices next month.

03c320

Do u have any pics of it?

Alswag

03c320, there's actually something I just thought of. If you do a modification similar to this (and can do it right), I'd recommend replacing the MAF housing with the housing from an M113 series engine. The housing in the M112 is about 2.5 inches, while the housing for the M113 is about 3 inches. Have 3 inch tubing going straight to your MAF, and bing bang boom you get more efficient airflow.
I don't know the size exactly of the throttle body, but I reckon you could bolt an M113 throttle body right on. Airflow opened, potential for power gains. You could get a used throttle body for a decent price off ebay, and you could also find an M113 MAF housing for about 40-100 dollars, depending where you get it.

Brew on you, good sir.

03c320

Alswag thanks for the info man. I will look into that. I am going def look I to my options before I start into this. I am mostly looking for ashtetic looks for csr shows, but power gains are always welcome. Lol I will keep everyone updated as I progress with this

Glyn M Ruck

Cheeky sod.

The Benz engines have well designed, non restrictive cold air intakes. There will be zero power gain.

If you want to mount a coloured tube plastic Jungle Jim under the hood for aesthetic reasons that is another matter.

tommy

You know me - I'd rather be sexy than efficient.

Needs a good detail, I know. Haven't gotten around to putting on the cover

solo money

wouldn’t it be smart to put a bypass Valve air intake to clean the air from all the dirt
