Proper air scoop set-up?

Im looking for suggestions to allow proper air flow when using a front air scoop on a P200. Ive heard that cutting slits in the cowls or cutting them on a slant provides a better ride. The increased air flow from the scoop will get caught otherwise causing more turbulence.

Is this true?

Doesn`t anyone know about these air scoops/front spoilers? I see that they are sold by SIP. Maybe someone from SIP can reply!
