I have been looking for ages and couldn't find anything. So today I decided to pulled out the ecu to find the No.
It's "0 261 200 402".
The ecu seems to be the same as the 325i ecu, so do you think this will work on my 320 with positive results?
If you just browser search 402 you will see what I mean.
When you say full 3.5" intake, do you mean just the CAI Kit or is there more to it?
