The humming sound that you've mentioned also manifests itself as a hissing sound in many cars. This sound is that of the filter shedding excess air especially when the engine gets switched off. My guess is that there's some resonance happening in your engine thats causing the humming sound. Its not from the filter alone. Having said that nothing can be done abt the sound without affecting the filter's performance

I had the same problem when i used a conical filter in my diesel sumo.
And Steeroid faced it when he used a conical K&N in his Dicor.
It does get on the nerves after sometime.
OT:Is there any improvement from the filter on the Diesel lancer?

My dear man, DO NOT make that hood scoop! In the monsoons you will end up getting a VERY WET filter. THAT is not good for your engine or wallet!

The filter is not making that hissing/ humming sound due to restriction of air-flow. That is induction noise. Either you live with it or try some rubber air pipes behind the filter to reduce the humming. This will help absorb some of the induction noise.
