I don't think there are any front end bypass filters other than M/C for the 4.6's, but I could be wrong. FYI the FL910 has a 3/4-16 thread and the FL820 a 22x1.5 thread...so unless someone's put in a different adapter, or a remote mount, I can't see how that works. Some pics of the FL910 on the car would be great. Edit: apparently the police cars have a different thread oil filter adapter, so if that's what you're referring to, that would explain the difference.

Bingo that explains it then.

The last Wix 51372 I installed was dome end (2015 production) and the Mobil and K&N are dome end too. I don't think there are any thread end bypass filters for this application, except for Motorcraft.

AC Delco PF1250 has a thread end bypass hide The last one I removed from my '04 Ford Ranger 4.0L looked very good and did not demonstrate startup rattle. http://www.bobistheoilguy.com/forums/ubb...d_o#Post4076564

Canadastang - The PF1250 is an eCore. I don't want you to be misled. It rarely freezes in Houston. When it does freeze, it is usually not a hard freeze. This may have an impact on the ADBV as well as the relief valve functions.

Well, the Mustang never sees winter, but the Lincoln certainly does, including the occasional cold start at -20c (or lower). Are e-cores problematic in cold climates?

Canadastang - the combo valve is made of Nitrile rubber and will harden over time at temperature. MotorKing has stated nitrile will last about 7000 miles or so. When the nitrile hardens, the anti drainback functions and / or relief valve functions may be impaired. I think nitrile would be fine at -20C. I had no issues down to about 32F/0C for a 5000 mile OCI / FCI.

No issues with nitrile during appropriate length runs, but the ecore I tried gave me horrible rattle starts even in summer. YMMV.

Maybe they figured that since their filter media tears they don't need the better flowing round holes. Otherwise maybe there is too much flow grin2. Whimsey
