The two sizes are 'basically' interchangeable but I prefer the slightly longer 14610/7317 size to the thimble size shorty for the increased media area. Some Nissan's have listed/spec'd the 14612 size, some the 14610 size, but I've never heard or seen a Nissan/Infiniti application that didn't accommodate the latter.
But yeah the shorty will be ok, just wouldn't be my preference over the 14610/7317 size.
sajac,
You are correct, many OE's and parts houses/quick lubes are consolidating the 7317 filter size to 6607 to simplify sku count. That said, I run the 7317 Ultra on my turbocharged 350z VQ35 even though it calls for a 6607.
