I contacted the manufacturer a while back, here's their response
Dear Mr. Bopper,
Thank you for contacting us. You will need the F106 valve. If your oil pan's drain port is recessed, you will also need an adapter extension ADP-106, but we suggest our adapter-integrated valve F106SW. If you have any questions, please feel free to ask, or visit our website for more information:
