Thanks for the input Max. As you know, I'm going down the throttle body route this summer and the details of your air box are very useful. I'll start off with the ITG foam filter...if I use Chas and if its too noisy, will go down your route.
In my view, there is always going to be a compromise between getting the best power, convenience, aural comfort etc.
