I have the cleaning solution and filter oil if anyone's interested. Don't use them anymore since I changed my setup.
Should fit all 2.8 V6 cars according to K&N - B5 A4 and C5 A6. Removed from a '99 A4 2.8. Could use a cleaning and the guide "dryer" duct has a tear in it. Still perfectly functional though. Kit is complete except for the cable ties used to hold the duct to the lock carrier. It uses standard cable ties which I'm sure will be easy enough to replace
