The main reason Im curious about this opening of the airbox for more direct air input, is because its the only 'no cost' modification which MIGHT result in a positive gain.... MIGHT.... Im here to see what others might have come up with having done it...

"Atomizers", "Tornados", etc are (from what Ive read) devices created by their developers to make them a lot of money. I refuse. This one however I will entertain. Hey, for a couple bucks and an hour or two of my time..

Oh, and 'engine roar, growl, throatiness" isnt one of my goals... If I get that too, no biggie, road noise from tire growl doesnt phase me in the least either.
