I have a 2016 Acura Ilx, just wondering In terms of size. If anyone has tried this... Should I just vinyl wrap the B-Pillars Instead?

The link says year 13 - 15, will these fit?

Vinyl wrap!
Sorry, I can't answer about the fitment of that specific brand, no idea. And they are a cool finish/color. But they appear like they will really stand out in a bad/cheap way as not coordinating with the color and design of the ILX. That's why I say wrap. But then again I can't see them in person. Unless you matched all trim that exact color, then I think you have a winner... (which can be done with wrap!)
Mine are wrapped gloss black, along with the front grille trims, and window trim; all of it a gloss black that really goes well with the Catalina Blue Pearl (and as of next week-the wheels too!). Non-car types think the car came this way, car people really like the matching...
