I agree......
The surface temp of my filter enclosure reaches 40C and above simply from underbonnet air at normal average driving. It is polished stainless and high up at the rear of the engine. Hotter during faster runs.Only an enclosed or protected air supply can efficiently guarantee lower temp air. So, a cold air feed from somewhere without gaps and suitable insulation is the best. The exposed cone filters would probably give optimum airflow but that air will not be cool. The modified airboxes would help control the air.
To my thinking the best solution is sealed air supply from a good source known to enable cool air intake. Maximising venting of hot air out from the engine bay is also beneficial, so bonnet catch extenders, air dams etc are options. If I remember correctly didn't Frankie have raised bonnet catches as well leaving a gap just in front of the windscreen? Chunky.....can you confirm?
Garret, your setup with a cold air scoop looks decent, I am not fully convinced that the side louvres allow much air IN but probably aid venting.
