Hello all,

Just for everyones info who lives in North America, just to let you know that K&N does make a filter for the Audi V8's but does not list it anywhere. I did some digging and found that K&N Part# 33-2573 is what is listed in Europe. This comes up as a 1988 BMW 535 on K&N's web site.

I just installed this into my '91 V8 3.6 and their is a marked inprovement in power increase, their is a nice engine sound now plus it is reuseable, bonus.

I picked mine up for $56 Canadian, I have seen them for $35USD on a few web sites.

Hope that helps
