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.
