These were cut during testing of the filter cutter I built. The FL400S filters I had laying around and the other two (L14476 and PH7317) were bought because they were smaller filters. Anyways here are the pictures of them cut open, Enjoy!
Personally I like the MotorCraft, then the Purolator.. They look the same but I think the CAN on the Motorcraft is stronger and is more easy to remove and replace.
The FRAM EXTRA GUARD.... I dunno.. I guess for a 3000 mile oil filter it will do its job.
however there is better for the same price or less.. Motorcraf Oil filtes are about the same price as Fram Extra Gaurd.
