[A4] Pre-chip checklist

[Brizax at aol.com]

the only time they are bad is if you over oil them and the oil gets sucked  
into the maf and ruins it, deff. replace the diverter valve when you chip it. 

I'm not  sure--but I think I remember reading somewhere
that the K&N might not  be the best option for the car.
Something about the fact that the K&N  allows larger
particles through than some of the other  oem/normal
non-oiled filters, which can be a problem over time
for a  turbo.  Turbo's don't react very well to
dirt/dust/and other  substances;-)

You might want to check on the Audi sites such  as
audiworld and others.  Search a little and if you
can't find  it--then ask in the forums for the car you
are interested  in.
