I am a first time Volvo owner, having picked up a used 2011 XC90 AWD 3.2. I really love the vehicle, but am having trouble locating "legit" performance upgrades for this model. I am used to owning domestic brands like Chevy and Ford and being able to pick up cold air intakes, computer chips, and exhaust fairly easy. I am wondering what you have done to yours for performance upgrades, and where to find such items. thanks for your help!
