the standard AFM sits inside the airbox, but u need the adapter from the AFM for your pod, if thats the one your talking about.
As for the pod, i know the K&N fits perfectly, not sure on others as i havent tried them , but if they are a similiar size they will fit in the box, as far as i know teh apexi one fits in with no problems .
if the hks is a mushroom pod, i think it may be to big to fit it.
NOTE: To anyone ive sold one to can u list your pod, as a refrence to others
