Green Air Filters f. RS6 ?

[eurovintage]

Looking for a set but can not find the, only the K & N.
Just wondering if the air filters on the RS6 are the same size as for other Audis with the 4.2L V8 ?
Maybe S6 .... Anybody have a part # ?
Thanks

You want stock air filters, better protection, plenty of flow.

Air filters are RS6 specific. They have metal screens on one side to help protect against damage. Other 4.2L have a completely different air box. I'd stay away from K&N since the MAFs are only a few inches away from the filters and could easily get contaminated with oil.
