Just wandering which would be the best solution for street bike if you guys have played with combinations on dyno...

My mc21 has a cutt out lid like tyga+ holes on top.

Inside i have fitted an unknown free flow filter element that has been cutted to fit exactly like stock.

I was thinking which would be better:

1) fit daytona free flow? is it avalaible?

2) buy universal foam filter and cut to fit? is there a good maker selling a piece to cut?

3) fit a good maker's free flow foam pod filters inside the airbox?

all sugestions welcome!
