prob best to think about actual filtration, heat soak than noise 
Bigger holes will let more engine 'warm' air in, let more dust/debris in (clog up the filter element)...... but sound louder

iirc i have about 4 larger holes along the middle, then smaller holes around them, my main cold air feed is directed right at the larger holes as to get most cold air in.
