I must have spent over an hour trying to find the right oil filter online. Can someone help? It seems certain Nissan part # may or may not work with the M37... There's an oversized version and does the submodel and/or trims matter when it comes to selecting the right oil filter? Never have I had this much trouble finding a part.

The most current p/n is 15208-65F0E, but it's the standard Nissan "short" filter and fits a ton of stuff. These superseded numbers will also fit:
15208-65F0D
15208-65F0C
15208-65F0B
15208-65F0A
15208-65F00
15208-65F01
15208-9F600

PS - The "truck" or "long" filter will fit all of the same applications as long as there's physical clearance. The current p/n for that is 15208-9E01A, with these supersessions:
15208-31U0D
15208-31U0C
15208-31U0B
15208-31U0A
15208-9E000
15208-9E000A
15208-7B000
15208-31U00
15208-31U01

Thanks guys
