Can anyone post some pictures of your Swiss Cheesed boxes, or any mods you have done to your stock box. Do you have any moisture problems? Looking at opening up for some more air, but have reservations on doing so.

Swiss cheese if need be but below filter and to the front as to avoid Engine compartment heat add a couple drains in the bottom ........
Or drill two big holes in the front or cut out a big V as others .....I "had" no additional water issue .... The rubber flap on the fender use to direct water right in the side of the box .... I have switched to a AFE Magnum stage II since ....

I used lots of smaller holes through-out the box

Just curious if anyone noticed a difference after putting the holes in the boxes? I recently installed a K&N filter. Would I benefit by putting the holes in or just leave it?

Better air flow helps keep EGT's down.

I have run the K and N but hated the oil running into the turbo. This was on a Dodge so I switched to the AFE and liked it better.
