This is when my G35 was reborn
I replaced plugs. All fluids- brake, power steering, coolant, differential(this is when I saw I had a rear main seal leak -$800), too scared to change transmission fluid at this mileage, and switched to penzoil high mileage & purolator pure one every 3k.
The G loves air flow so installed ztube with k&n. Motordyne 5/16 spacer and magnaflow catback
This weekend just saved myself $900 when the dealer wanted to replace my driver power seat rail when all it needed was a new gear for $20 and 30min of my time

Also, I can't believe how low you've kept your mileage
