Steve/Simon,

I am under the assumption that the SL55 inlet pipes MAY work. However, I haven't been able to put my hands on them so I can't say for sure.

Here are the part numbers:

Left - 1130942382
Right - 1130942482

They are around $20/ea.

I was going to purchase them, but one would have to ship out of New Jersey (to TX), and the other out of Germany - so who knows how long it would take.

There is a guy on MBWorld selling the SL55 Air-boxes and inlet tubes if anyone is interested, but I think he wants like $225 for the setup.

I will likely try to make my own inlet tubes with less restriction. We'll see what I can come up with.
