Most usually buy or make an adapter for the Air Flow Meter to attach it to whatever air filter they are using.

Well there is the air filter box that holds the stock air filter and then there is the AFM that sits on top of the air filter box. So you are eliminating the air filter box and stock air filter and replacing that with a different air filter, typically some sort of open element design and then attaching that to the AFM which in turn connects to the intake tube that runs to the throttle body on the intake.

Why do you want to do this? I don't think anyone with a stock engine has documented any "improvement" by making this mod. Or?
