Fram spin on filter part number to suit system 1 remote mount 221-90004.

Can anyone help me with the Fram or K&N spin on filter part number to suit system 1 remote mount housing #221-90004?

 

Most standard remote filter bases including the 90004 use the 3/4" by 16 thread which is Ford/Mopar style. Don't know the K&N number but Fram is HP-1.

 

I am not positive, but I believe that that base uses a 1" -12 thread. Measure diameter and count threads for one inch length (not trying to sound like a jerk but some do not understand thread count). If it is this pitch and diameter Fram filter PH 9010 will work (not a race filter) or K&N 1014 will work. You will have to make sure the nitrile gasket will fit your base. Hope this helps.
