I haven't heard of this so I checked the OEM parts catalog.
There are two versions, the base part number (driver's side) is 1k0 959 701 L. The 2005 have suffix mx1, 2006 have suffix mx2. There is no indication of any other part number. ECS tuning shows the part number as 1K0 959 701 Q Z3E and no difference in years.
I would say that they will fit but I don't know why the catalog and ECStuning show different part numbers. http://www.ecstuning.com/ES485186/ Here's a direct link that may help you.
