I broke the clips on mine trying to install the cabin filter panel over the M3 strut brace, resulting in the same leak. Any interference from the M3 brace hardware with the cabin filter panel also prevented the gasket from sealing properly. I was able to fix it by adding 3/8"x1/4" EPDM door weatherstripping to the cabin filter cowl, where it seals against the top of the profile gasket:

Good info, thanks for sharing it! I’ll have to add some of that weather stripping I think my cowl also has a few broken clips on it. I do run the engine cover as you can see and haven’t had any issues, although I haven’t driving in any significant rain in months because we are in a drought lol
