Air filter box question!?!?

I have heard of that also. I was advised to do that on my old Suzuki street bike, but I hadn't thought about that for a truck. I just ripped out the whole thing (on my diesel)and got a giant ag filter instead. I on the other hand need cooler denser air, so in the summer, I need to direct outside air in. In the winter, not so much.
You could just try removing the long suction tube first. That way you'd see how it worked without having to put holes in anything. I'd strongly suggest that as an alternative.

On my Dodge I manufactured a new air box. The old setup ran to the right front fender and in the winter when I was driving down a snow covered road it was sucking snow into air box. So I copied a K&N set up. I used a piece of 3" ABS pipe and a 45 degres elbow. Cut a new hole in the air box and covered up the old one Then directed the pipe to the right front and put some tin around the new filter to box it in and protect it from sucking in to much dirt and bought a new air filter from York Auto to fit on the end. Seems to be working good, definitely notice a little better pickup and gas mileage. The whole thing cost me about $30 and an afternoon in the garage.
