Got it today.
I looked up some optional filters for it as well.
There are two lengths available for it.
Short:
AC Delco - PF53
Amsoil - SDF57
Amsoil - EAO57
Fram - PH3614
Mighty - M3614
Wix - 51348
Long:
AC Delco - PFL400A
Amsoil - SDF34
Amsoil - EAO34
Fram - PH3600
Mighty - M3600
Wix - 51546
I've physically tried the Mighty filters on it. The rest were looked up online.
by crossreferencing the various numbers.
