I found a great deal on WIX oil filters. After I shared my findings to my audi forums friends, nothing but disgust was posted about WIX filters. I did my own research on these and found them to be highly recommended. But a highly recognized member just said nothing but bad things about them. This is of concern. What are your thoughts? I usually use MANN oil filter for my audi a6 2.8 v6 (wix 51355) I also bought some WIX for a new to me 07 infiniti m35(wix 51358) In the infiniti community, mann filters were not spoken of. And wix came recommended. In the audi community, MANN came highly recommended and WIX as a comparable to MANN. Are the wix that bad? Should I cancel my order?
