Same with my 2004 Altima. I could never figure that move out since the 14610 fit just fine. Maybe because Nissan specified the shorter filter for the V6 and the longer filter for the 4 cylinder (?).
Actually the shorty 14612 was spec'd for my 03 Altima 2.5L. I always used to 14610 size except once when I fit the 14459 on it.
The shorty 14612 is also the spec'd size for 2010 G37S. Put my son on to the PL14610 size and he has no issues with the fit.
No idea why Nissan specs the shorter filter where the longer 14610 easily fits.
The only thing I can think of for Nissan or Purolator recomending the 14612 filter is, to possibly help cut down on some of that notorius start up rattle(timing chanin rattle). I know that anytime I have used a larger filter on my Altima, the startup rattle was worst. And the larger the filter i.e.(#24458-discontinued), the worst the noise.
