I'm guessing you don't have the AFM "adapter" yet ?
Our AFM's don't have a lip or flange on them .......so these aftermarket adapters are needed that provide a lip so an aftermarket cone filter or hose can be attached directly to the AFM .
Just get a 3" adapter , or the biggest you can find on eBay and then get/make a coupler for your hand-me-down filter .
