So 2o minutes of searching, All the V8 air boxes I see on crossfires are infact MB V8s that have been swapped in. If someone infact knows the answer to this question, if they could chime in please and perhaps post a link to all the info that is already available that I can't find.

Well, I did find this! I really like the way it looks!
