ive had the coathanger GAB in for about a year now, been readin up on the OSCAI, 2nd hole twoards the bottom that goes into the stock air box, my question is how do you get a pipe to fit snug on that part, do you use duct tape? and where do you put the end of the tube? below the front bumper? thanks in advance

 

You could use some pipe that is used for clothes dryers. Put it into the hole of the air box and attach a hose clamp to it once it is in the air box to keep it in place. Then you can bend the pipe down so it barely sticks out below the splash guard.
