Just added these chrome vents to replace the black ones. No need to remove the bumper. Just get a plastic pry tool, start on the outside and it pops right out. 5 minute job. Bought them here: https://www.ebay.com/itm/294438174611

 

Many people do not like the chrome accents and buy delete kits, but I actually like the chrome. From your pictures, it is hard to see how those inserts fit into the front end as a whole. It it possible to grab a zoomed out photo? Also are the trim pieces good quality?

 

I love chrome so this is a nice upgrade for me. They fit perfect and the quality is excellent.

 

Enjoy chrome while you can.
MINI is moving away from chrome in the next couple of years, to stay green.
