I want to keep my stock airbox, but would like to get better air flow. What mods have worked with gettint the soaked or full of grit. Holes in the bottom or sides

Thank you

 

I drilled them in the bottom. No sign of water and it's been probably 25000 mi. ago. I drilled in each of the squares w/ a paddle bit.

 

I attached a 4" drain pipe elbow to the bottom. And just installed a Amsoil Ea nanofiber dry filter.

Did any of these modifications add any bennifits?

 

I drilled the bottom of my 06 air box also, 3/4 or 1 inch speed bore bit for wood, it fit in the little squares, seems to breath better, I have an AFE drop in filter, with my XZT box, best mileage so far is 25.9 on paper, average about 22 or 23 all highway, all on paper, the over head only tells the temp, acurately hahaha

 

Just how slow are you driving to get 26mpg??
