Pod Air Filter

[Whoops]

Supporting m in sc's first point is the fact that the airbox is a resonant chamber.

see the explanation here. http://motorcycleinfo.calsci.com/Airboxes.html

That just reinforces my conclusions that performance modifications are far outside of my (and probably most people's) expertise. It's hard for me to easily dismiss the engineering expertise of people that spend their entire careers perfecting their knowledge and experience. However, most car and motorcycle forum I have visited typically have a number of "essential" modifications everyone does. To me they seem to be more fad than improvement. The article touches on exactly that with the old mod most of us probably remember about opening up the air box. While I don't particularly care for the CalSci windscreen I bought for my FJR, they do have a lot of great information on their site. Their windscreen cleaning formula for example, works brilliantly.
