    Air box mod = remove filter, pull off funelly thing at the bottom of airbox, refit filter.

    When you remove your air filter, you will probably notice it is only half dirty. Theory being that when the funnel is removed the car breathes through the whole filter instead of half of it.

    Some say it improves performance, gets rid of flat spot and means you can hear turbo spinning up louder.

    I don't know if it improves performance or gets rid of flatspot, didn't really notoce on mine, but I can hear the turbo a bit better..... this all be placebo effect though!

    Dmf question.... ain't a foggiest! An expert will probably be along shortly.
