Ok, I just got 4 new oil filters. They are shorter than the ones I previously used on my 2002 by about 3/4". the box says Xterra-WD22-VG33E-Production Date 09/02. The part number is 15208-65F00. Any one got any clues? Im not sure of the old part number but I know that the old box didn't list the Xterra on it but did list the VG33E. And one more thing my Xterra was built 03/02, 6 months before the production date for this filter. Kinda sounds like a Cyclemut question. If any one else uses these or knows whats up let me know please. I'm kinda hesitant about using them.
