Well i know some guys like to get the airbox breathing by cutting a hole in the top but i went all the way!! Well as much as one could whilst keeping some structual integrity in the box.

And i did this because i have the K&N airbox replacement filter. There is a heat sheild wrapped around this sucker and sealed against the bonnet (poorly).

Top end power gain was quite noticeable!
