My daughter just got an 08 Ford Fusion AWD with the 3.0 engine. I looked up Fram Ultra filters for this engine on Rock Auto and found that it lists two different filters. The XG2 "before 9/25/08" and the XG10575 "after 9/25/08". Is that the build date? If so, did something change with these engines mid year that requires a different filter? Thanks for any info.
