Depends how close to head swirl flaps are, if they are protruding from manifold when open mesh will get in the way. What about vibration, it might be OK for short distances in F1 but will it survive 50k miles? If some bits get loose and rattle around they will surely wear through sooner or later. It will also reduce airflow and power, increase back pressure and make turbo work harder, less efficient, increase charge temp. Many diesels are known to clog intake manifolds with carbon build-up from EGR+engine breather system so it could clog up mesh at least on the swirl flap side as airflow is lower on that side most of the time.
