Tuning up my 2001

I was wondering if I could actually tune up my 2001 Nissan Maxima? If there are some things I can do what are they and what will I need? Thanks for the help.

oil change, oil filter, fuel filter, air filter, pcv valve, spark plugs, fuel injectors. it depends on the mileage. there are things that should be done at certain intervals. i think it's 30K, 60K and 100K miles. call your nissan place and tell them how many miles your car has and ask what kind of service your due for.

It is common that the fuel filter in the max doesn't have to be changed and because of its location. It should operate fine for years. Correct me if im wrong. Also anyone suggest an upgrade in performance spark plugs?
