Looks good Robert with filter high enough above engine to receive cool air via louvres thumbs

I wouldn't worry about water ingress under hood, not much gets in anyway otherwise it would be a lot dirtier there.

FWIW my M3W had the K & N style filter low down and up front. Torrential rain seemed to have no effect on its performance.
