So this system does not work if you have done the throttle body mod?

It works, but trust me you want to go ahead and do the full coool air intake and not hte warm air intake like the Ebay sale shows. I had a Spectre intake on mine and went ahead and got the tubing to make my cool air intake to replace the OEM intake. I also got a V8 intake to go with it. Not more than $130.00 for the entire intake setup and works great with the MAF and TB.

That is not a picture of a V8 cover, V8 covers do not fit as I recall. They may look the same but the attachments points do not match the V6 engine.
The V6 front part does not fit the V8 rear part.
Only one V6 cover assembly fits, the other are too high and rub on the Hood liner. and mark the cover.

If there was no difference between the parts they would not have different part numbers.
If you are changing the cover then you should get the one that has the bigger filters or why bother.

Use #A 112 090 11 01 - main body.
Use
#A112 010 04 67- front piece.
Use
Filters, K&N's #33-2181, or OEM (paper) A 112 094 00 04

As described in post #1

The 1120940004 p/n is for the filter elements that fit into the A1120901101 engine cover box. (See post #1)

That's certainly a V8 cover. it's the S430 cover. You can use the V6 front with the V8 back.

OK, I had V8 backs and they did not fit V6 fronts.
What are the part numbers for the record?

How do you have to modify the larger side of the tubes? I know you recommend the spacers going into the engine cover / air boxes, but what about the other end?

Would it make more sense to use a generic 3" intake tube? Something like this?

What kind of intake tube set up is that?

here they are:
airbox: 112 094 00 04
https://www.crossfireforum.org/forum...mber-90534.jpg
Front cover: 112 010 04 67
https://www.crossfireforum.org/forum...mber-90532.jpg

Yes, it rubs the liner.
https://www.crossfireforum.org/forum...rbox-90533.jpg

I think I got the tubes for the W123 (they were cheap and on Ebay and just the right size for the airbox.) I got the Needwings Devil Horns, but only used the tubes through the front and not the horns themselves.

As mentioned previously 112 094 00 04 is a filter. That molded in number is showing you what filter fits.
I think V8 parts start with 113 xxx xx xx. Maybe not (?)
V8 air boxes mount in different positions if I recall and this puts the front part too far forward. I had all these parts and junked them at the tip.

I have a question about the intake tubes. Instead of the benz parts, I used generic autozone 3" tubes and cut off the ends of my old crossfire intake tubs to connect them into the front end radiator fittings for air intake.


Does the small size of those fittings basically make this entire mod useless, as the size of the air intake is the same as OEM?


Or do the bigger filters/tubes mean that more suction is created or something for more air? The cold air intake side of the tubes is the same as the original though.

I bought the V8 because some where on the forum I thought some one had mounted so I bought it doesn't fit so in the trash it goes bought one for the SLK320 and it fits perfect.

The fittings by the radiator have holes which are uninterrupted but the filters hava million or more holes in them. The smaller holes in the filters have more restriction just because they are so small, if you have larger filters fitted then you have more holes and the restriction in each small hole is less of a problem as there are more holes in total.
You can compare it to a can with a smal hole leak and the same can with two holes the same size, the can with two holes will drain first.

Sorry to inform you but you will not gain any more air flow with the SLK320 cover. It is the same size/volume as the OEM cover. Only good for the bling factor. That's why it fits exactly. Just resale the V8 and SLK covers and get the correct C240/320 cover if more performance is what you're after. I bought mine from a salvage yard for $85. Search for a 2002 M/B C320 cover in your area HERE....

I'm actually very good at planning and micro managing, by the time I have proved to myself I could do a project I forget about it and move on to the next. Just ask my wife, I planned for a big family, had one child and then moved on to the next project. It saves money and leaves lots of time for more planning.
Around the house I'm a virtual handyman.
My motto, how hard can it be?

As for the clubbin', there weren't too many seals on the ice this year, so we shot a few polar bears.
I love your approach 180. I built a stone wall around my house 20 years ago and left 3 of the 14 columns without caps on top...I pictured them in my mind and that was good enough for me. Virtual stone wall completed.
