[Biturbos4] First of my own wrenching of my '01 S4

I had a K&N panel filter in my '90 CoupeQ, initially I though the intake sound got louder (pretty cool), but no performance gain I could really feel.  When it's time to clean and re-oil it, I found out that improper oiling (ie. too much) can kill the MAF, plus I read a few independent studies that K&N doesn't flow much more than a stock paper filter, and its filtering performance gets much worse than stock, so I went back to a oem.  Lo and behold, I felt zero performance difference after the switch, and it even sounded the same as before!  Base on that experience, I'd say keep using stock filters.  In addition, if you let more air through, you have to let more dirt in at the same time, and more dirt = bad for engine.
