Just purchased a used 2005 G35 and i want to know what other small pieces as in Fuel pumps, Spark plugs i need to have my car running at its best and keep it well maintained.

 

G35Dio, don't worry about those parts until they become a problem. I've not heard of fuel filter issues from the guy with over 300k miles on his G35.

 

Suspension bushings, front struts, rear shocks, rear differential bushing. Those are the main ones to start inspecting.

 

Glad you mentioned that because i do feel my bushings are due for replacement. I will check all of the different parts you mentioned and make sure this car is driving and running 100%

I also want to know about anything i should service engine wise

 

Replace oil, keep an eye on the level.
