Since my roadster are waiting the end of winter in my garage, i've done a few mod..

74 mm throttle body
MAF
C240 2003 air box
K&N filter
Magnaflow exhaust to be install

Now my OEM 2.5" intake tube wont fit. Are you buying the C240 3" intake tube? And what about the black plastic part that the intake tube connect to, just beside the radiator?

I've been searching local junkyard for that tube but no one have them.
Maybe I'll just go the Mercedes dealer and order it.

Anybody got the part number?
Any other suggestion?

 

The C240 airbox tubes don't go through the radiator support but rather connect to another tube right before it so I don't think that will be the perfect solution. A set of tubes from a Mercedes V8 like the 430's or 500's might be a better fit for you. You will have to trim the driver side a little for it to fit but if you take your time and only trim it back a little at a time on the bottom, it will still seal up fairly well and keep the hot engine bay air out of the intake.

 

Thanks for the tip

So I need V8 intake tube, but what about those plastic support beside radiator?

I guess i'll just removed the OEM ones. Is the 430 or 500 benz have those?
