Try Pipercross, they do a lot of replacment panel filters.

Aside from potential longevity of filter life vs the oem - I don't believe there are any real world gains to be had in the intake area.

Many of the results I've seen show no gains, and some mumurs of oil from the K&N's being blamed for dirty MAF's - though that's likley due to over enthusiastic oiling when filter is being cleaned.

i agree that their is no performance gains but like the way it makes the car sound! think Ive sorted it with the help of my local Audi dealer supplying measurements, it is the same size as the 2005 model apparently will soon find out as have ordered one from jays performance filters will let you know many thanks eugene

No changes in the intake area between B6 and B7 variants.
So pretty much all components under the bonnet will be interchangeable.
