Re: 147 CDA installation? Easy?
I was replacing mine due to tree damage (don't ask!). The original air intake and filter box were damaged so I ended up using a saw to cut them out!
The cda kit had everything I needed. Used the original piping to connect to the CDA, supplied with a bracket which you need to find somewhere to attach to (used a point below the battery tray) and comes with a flexi pipe to route to a suitable point to catch fresh air. On my 156 I have it positioned facing forwards behind the little grill next to the fog light. So gets fresh air direct from outside.
Like I said, if you get it from Angel tuning I'm sure Nigel with give you some tips for the 147 fitting. He comes on this forum too I think so you might even get a post from him.
