I think mine just had a small semicircle cut out and I extended it a bit more.Mine already has a slit in the bottom of the cap from the factory. 22 ATAS ES DCT. Not sure if they’re all that way.
That is what I did, didn't need much more.Yes, on 2023 ATAS DCT, I have small slit, but it is way to small. Just cut a bit more?
