The AA filter must come from the OEM supplier based on the lettering on both and the similar frame. See the EU vs US and then the part number on each piece.

Hmm... thanks for posting the pics. Looks like the AA filter may just be a stock EU filter with a different cap. I think there were posts about the spring loaded knob being a different length for non-NA cars in the early AFE treads. So, a cap change may have been required to fit.
