Filter placement somewhat goes against the whole shaving/tucking theme going on as well. If anything, they should have made a nice bracket to place the filter vertical...then the spillage won't be as bad, and it will actually have a better chance of draining back to the pan anyways.

Course, they can get around the current setup, but gotta line that wheel well with rags. :\

Also, they could shorten the intakes to fit some filters....or get something and ditch the MAFs.
