I heard somewhere that they are magnesiums, is that true?

 

Yee

 

. . . . . . and the valve covers. Here's a little more info on the 113.

 

Hmm.....I'll keep that in mind. Unfortunately I only bought the intake assembly in the auction.

 

Thanks Marcus, As usual you have enlightening reading. A real eye opener. I certainly didn't know about the 8 valves in the intake manifold which remain closed until around 3700 rpm. Do you think the later and upgraded Motronic ME 2.8 ECU could be retrofitted to the C43 to improve performance?

You can see the butterfly valves in the picture at the beginning of this thread https://mbworld.org/forums/clk55-amg...ook-right.html
What do you think of removing the runners in the middle of the manifold?

 

How is the 05 intake setup gonna be an improvement and work on your W208 CLK?

 

I don’t know what impact the ECU would have, but the ME 2.8 throttle body should help. ME 2.0 throttle bodies are 69mm, while the ME 2.8’s are 74mm. The AMG 55 (NA) TB is 74mm too, but it’s a different part. The ME 2.8 430 injectors are different too, but I don’t know what the difference is. Better atomization? More flow? Both? Neither? The ME 2.8 55 injectors are different than the 430’s, but at 27% more engine capacity, that’s expected. Many other 2.8 parts are "different", but I don’t know if they produce more power or just aid in drivability (O2 sensors for example).

Just so I don’t completely hijack the thread, the intake manifold for the C43, CLK430, CLK500, and CLK55 (all years) show the same part number in the EPC - 1131400301.

DOHC, did you buy a 63 intake (later year)? A 55K intake/blower? Or?

 

IIRC the intake was advertised as a clk500/ml500 intake but I need to check again. As far as it's use to me: 1 will be a plethora of spare parts and 2 I can have the intake and tb ported and gasket matched while still being able to drive my car. Other than that the magnesium intake should be lighter and dissipate heat better than an aluminum one.

While I do have an e55 amg setup in the works. It will be some time before the install happens. Little extra info, I'm also using the 05 heads off the e55 setup for the same purpose to be ported and gasket matched to that intake. I will however swap the clk55 cams, lifters and valve springs to the e55 heads tho. Also plan on getting a set of those box headers to be ported on the inlet and gasket matched to those e55 heads. All 4 of those parts will be bolted on as an induction package as I call it.

 

Marcus r u sure about this I have a feeling that all of the N/A 55 throttle bodies r ALL the same size.

 

I just checked again and things have changed a little, but not much. The original TB part number for an ME 2.8 (2001/2002) CLK55/E55 (NA) was 1131410124. The original part number for a 2001/2002 CLK430 was (and still is) 1131410125. The 1131410124 appears to have been superseded by the 1131410125, as the 1131410124 part no longer appears in MB of Annapolis’ Internet parts lookup AND the CLK55/E55 now show in the vehicle reference for part number 1131410125.

The ME 2.0 TB for a 1999/2000 E55 is part number 1131410025. That’s the same part used on a 1999/2000 CLK430 – and the early CLK430 definitely uses a 69mm TB.

Here’s the MB of Annapolis parts lookup website. Just plug in the part numbers and look at the vehicles that they cross reference to. BTW, note the price difference - the early 025 part is over $1K more.

 

I remember some years ago there being a thread on the differences between some manifolds with having an AMG stamp and others not.

 

Found it....
