My beloved 2003.5 sedan just rolled past 60K miles and I don't want to take her to the dealer for the 60K miles maintenance - because I know it's going to cost $$$$$! I want to do as much of the maintenance as I can. What is the most important thing to do first? Do I need to change the spark plugs?
I'm planning to change oil, check brakes, and clean the air filters.
Feedback from all you DIY'ers would be greatly appreciated.

 

Partial transmission fluid and differential fluid change is easy. No idea about the fuel filter though. Has anyone done this?

 

You could just take it to a regular auto repair place. Most do the 30/60 maintenance items, and usually cost a lot less. Anyway I wouldn't worry much about the spark plugs until you get 100K miles.

 

Transmission fluid change, flush is better but more expensive. Rear differrential service. Radiator drain/flush? Oil and filter change. Rotate tires. Power steering fluid change. Optional: throttle body cleaning and fuel injector cleaning. If you plan on keeping your G for a while, do all this stuff.

 

If you were going to change spark plugs, what would you guys do? Stay stock. Those of us with mods may want to upgrade to iridium right?

 

All fluids and filters, and complete brake inspection and service. If you're feeling rich, change the plugs too....they'll probably go further but you'll benefit from new ones.

You can buy the parts and do it yourself. I just bought floor mats from this guy, so he good.

Kegels, I recently delt with the same issue, I had the dealer just do the transmission & coolant flush service and an oil change (around $240); I replaced my pads & rotors myself (stock rotors & stillen metal matix pads- no dust, love em; relatively easy); I replaced spark plugs myself (no mods, just stock plat tip, not easy, first time for me, easier next time around); I also replaced the in cabin micro-flter, and engine air filter; I used the 2003 G35 Service Manual as a reference, I am no auto mechanic, but was able to get the job done and save some cash when I needed it, was between jobs at the time. If I can provide any other info let me know.

 

I would go with NGK Iridium IX's.

 

I need to go back to an article in SportZ to find out if going down in temp is what I need. Iriuduim is a step down, correct?
