! have a 2000 F-350 superduty with a V-10. I replaced my original airfilter with a Airaid an in the process had to remover a round cover that houses the MAFS and I am not how it should fit within this round tube. there are arrows on the face of it, but I no way to know how they should line up. Can any of you guys help me? All help greatly appreciated.

 

Most of the time the arrows point in the direction the air goes in.
