How does the M2 Medium mount?
 

I bought one 2nd hand, there are no brackets/holes. are the couplers the only thing that holds it in?

Yes it just sits in place pushed on to the duct work .Held by the pipe from the turbos and the pipe to the elbow .

yep.

Interesting. The PFS has a nice bracket on the bottom to rest on the frame rail....

Make sure you put something inbetween the bottom of the intercooler and the bar it sits on. The aluminium is much softer and will wear. I juts used some old rubber floor mat.

Thanks!
