How does one remove the air curtain covers? Any other parts required? My are blocked off on my 2016 M235 6MT, Midwest delivery car (Kansas City) in Feb 2016.

Old question, but I've been wanting to know the answer since last summer.
Any info? (please)

Just pop them off and Dremel the holes open, problem solved! Or if someone could provide a part#, would be even better...

Dremel what holes? On my M235, the air curtains on the bumper cover are closed off with a black piece of plastic, but within the front wheel wells, the air curtain vents are open. So, to me it looks like the only thing I'd need to do is pop out the black pieces in the front portion of the bumper.

My highly uneducated guess; The air curtain creates a 'curtain' of air that goes over the face of the wheel reducing turbulence and thus drag. The aux coolers exhaust their hot air inside the wheel well, ahead of the front wheel. With the air curtain in place this hot air can not exhaust easily away from the vehicle possibly reducing the effectiveness of the the aux coolers. Obviously if there is no aux cooler the air curtain can remain in place with no effect on cooling performance.
Also turbulent air around the wheels aids in brake cooling.

They are opened on the convertibles and on the coupes everywhere except N/A market, figure that one......

There are provisions on the trim piece, where there "would" be vented rectangular "holes". They're simply just molded shut.. It's been done by a couple of members, the result is the same as having the factory air curtain, open. Might be able to notice if you went up really close, looking for a flaw, but otherwise from the pics I've seen, they came out alright.. Taking them out may work, too, but also may see the tab slots from where the trim locks in. Especially on a light coloured car..

All you need is a VIN # from a vert, and order them. Probably less than 20-30ea, my guess..
