I am at 97K miles on my 2007 LS 5 speed. I have not done anyting to it except for 3k mile oil changes, replace and rotate tires, air filter, and fuel filter. I am thinking I need to atleast change the plugs and wires, antifreeze, brake fluid, and in-cabin air filter. What else do you guys recommed?

Also what spark plugs are recommeded for a 2.2 litre?

 

Trans fluid, coolant, and plugs, at 100k. No wires just coils/coil pack and that would get very expensive replacing those.

 

I did plugs, fuel filter, cabin air filter at 75k.
