The 2000 Altima manual and 1999 Altima manual differ in their specifications for spark plugs. The 2000 recommends using NGK PFR5G-11 for spark plugs, while the 1999 manual specifies NGK FR5AP-10 for spark plugs. Does anybody know of a reason not to use the 2000 year specs for a '99? Would it be better or would there be any harm to use those specs? While the '00 car is essentially the same as the '99, there were some tweaks to it to bump up the acceleration and horsepower. Both spark plug types are platinum and look like they have the same heat range.
The models also differ in the 2000 recommendation for power steering fluid being Nissan PSF II while the '99 is Dexron III.
