Holes in airbox

[Dave]

I put a couple of holes in the airbox on my stock 4000Q.
It seems to run a bit better and definitely sounds nice.
I am going to do some before and after stopwatch tests on
the 90Q 20V and see if it really makes a difference.  A
bit of screen siliconed to the inside of the box should
cut down on the leaves, bugs and small animals.
