2018 S60 T5 Dynamic AWD, new to this, looking for advice

[liamchesley]

Both my parents had Volvo's when they were kids, and I recently got the 2018 S60. My dad loved it, so he decided to one-up me, and got the 2019 S60 T6 polestar. I've always been interested in cars, as well as my dad. I probably got it from him. I have very limited knowledge on where/how to start. I've been looking at performance air intakes, turbo intake pipes, and smaller modifications. The problem I'm having is that there doesn't seem to be many places that sell parts that are specific to my vehicle. Would part that aren't specific to my volvo fit if I were to attempt to install them? Where would I go to find quality parts for my car? ANYTHING helps. Just looking for a good starting place
