Hi Folks,

     I've been spending way too much time with my head stuffed under the
hood of my
9090q20v lately just staring at the airbox.
     I've decided that the swiss cheese approach is not one I want to take.
  I'm not
really convinced that the K&N cone mod is the way to go either since I'm
having trouble
visualizing how you would direct cold air directly to it.
     Here's what I AM thinking about.  Suppose you were to cut about a
three inch diameter
hole on the inboard side of the airbox and attach a straight-as-possible
hose to it which is
routed as directly as possible to the front of car with a slight flange to
direct just a
little more air to the hose.  This would roughly double or more the open
space from which
the filter box sucks air.  I was thinking that a K&N filter inside the
airbox might be
a better way to go than the cone mod. You might lower the resistance (K&N
filter) and allow that
filter at least twice the outside breathability of COLD air coming in from
the front of the
car.
     I'm looking for opinions on this mod.  I KNOW you folks have opinions
:-).
     Let's get back to talking Audis.  TIA!
