Yes I am talking about the plenum, I guess every country has different ways of saying things. The reasons I want to replace the stock one are:
1. Response (I am upping the turbo to a 3037)
2. Easier acces to fuel rail, etc.
3. Cleaner air piping configuration
4. It looks better (stupid reason but true)
I am not concerned to much about money but I would like to avoid un-neccessary expenses. Of course intercooler, injectors etc.. are all being swapped out for high performance items.
