Cold air/Ram air example
Cut a 2-1/2 " hole in side of filter housing, insert the air cone without the bracket through the air box and clamp the hose up close to hold in place. Modify as necessary the bracket on the other end to attach behind headlamp or other opening in the front of the vehicle. Shorten the hose as necessary.
This one sheet of paper covers the air box modification.
I don't know why it's not included.
