So I have been trying to find one, and have seen some on the forums, but can't anywhere to buy one, it seems a intake system for the non-s cabrios are few and far between. I want one thats really loud, can anybody help me out.

 

Check out the DDM Works intake for the MC. It is loud and it sounds GOOD!!!

 

there are a couple of threads out there under 1st Gen/MODs/Cooper for the CAI. check out this thread

I have the Works DDM CAI that you can get one from Way Motorworks. I've had it since MOTD, installed by Way himself.

Is it loud?? dunno about that, I don't let anyone else drive my MCC . but it does sound cool (so I'm told)
