I was monitoring a few Acura on-line parts web sites to see when are they going to update their databases with TLX parts and found a few today:

... and here is another one

It looks like they distinguish the i4 from the v6 by transmission choice, but not sure how to get to the V6 or the SHAWD....

Somehow the diagrams and images don't show. Hope they'll fix that soon.
