M135i and the shed
How much bigger is the Cozzie filter Poob and would it make any difference to the amount of available air? I can see It helping up to a certin point then thinking it would be governed by the ITG hose size.
Basically i bought the Cosworth one when i was planning my own induction setup. This size of filter was matched to a 300bhp output hence why i went for it. Obviously i consulted ITG before buying it. ITG then brought out their kit and i decided to go with it but utilise the filter i already had. No more scientific than that.
Presume the standard ITG fikter is sized to cope with standard and mapped cars.
