Hi Guys! First off all, thanks so much for your comments and assistance on this trouble. I don't know how the intake manifold from EA63 looks like, if you can provide a picture, I'd really appreciate it. On the other side before proceed to search and buy another intake manifold, need to confirm with some of you, the final lenght of it, i.e the factory intake manifold has 51,8 cm between cylinder heads where the manifold is connected to them. Another point to consider on this, is that the EA71 cylinder heads are not in line, what I mean if you take a look to the following pictures, you can appreciate that the factory intake manifold has a little curve on the driver side.
The manifold that I bought from EA81 is straight, for this reason need to know if the EA63 intake manifold has the same format that the factory manifold.
Regards!
