I made a shield on the top front with 2" foam (like you use on your house windows to insulate an a/c unit). I have a K&N drop in with that. So there is a significant additional opening (bigger than the throttle body) but some heat protection and a little more sound. It is a little louder but not ridiculous and I think I notice a performance increase. It can be easily changed for dealership visit or inspection. I see recently there is a UK company offering a filter with the top end opened (which would be exposed on our cars) or the make an adapter ring that can be used with universal K&N type filters.
