1. What spark plugs should I use for the maxima? the stock OEM "NGK Laser Platinum" spark plugs are ~10$ EACH...is that what I'm supposed to use?

2. Is changing tranny fluid a required maintence step? I didn't see it on the car care guide in the "Shop Talk" or in my owners manual

3. Fuel filter, same as #2...didn't see it as a required step for car maintence? but is it required?

 

yes use ngk, they are about 10 from the dealer, i paid 11, some people use colder copper plugs for some reason i cant remember.

yes change your fluid

yes change your filter

all these things will help to keep you car in general good health, and will improve things like mpg and how smooth your engine runs

good luck
