2005 Infiniti G35

This is my first car so I’m trying not to screw it up… Got it with 175,000km on it in May (2023). The previous owner had already installed a plenum spacer which is a common modification for VQ35DE’s. This particular car has the Sport Tuned Suspension Package which comes with stiffer spring rates and wider wheels and tires (225-40R19’s in the front and 245-40R19’s in the rear). The plan is to address the wheels tires and suspension next summer…
