2004 G35 Coupe spark plug and maintenance inquiry

[fatire_mtb]

I am a one week newbie with my G and I love it. As the initial exuberance of driving is settling in some practical car ownership thoughts are coming back in to view. The first thought is regarding general maintenance and tune-up information. Such as what spark plugs are recommended? At what mileage should I replace the O2 sensors? How often should I replace the A/C filter?

If any of you experience G-owners are kind enough to throw in any other related tips I am definitely appreciate your help and would like to thank you in advance!

Owner's manual will specify plug.

O2 sensors can be judged by looking at the duty cycle on a scope. Should not be very soon, but there are exceptions.

All fluids should be replaced every two years. Annually replacing all filters will help longevity a lot.

Since the car is already 3 years old why not start out RIGHT and replace every fluid immediately [PS, Coolant, Special ATF, Diff, of course oil].

Depending on how many years past warranty you want to keep vehicle research AC compressors and how to squeeze additional life out of them.

Make sure you use only demineralized or distilled water when mixing coolant................tap water contains too many minerals and clarifiers.
