New owner needs advice on upgrades

[TypeA]

Hi all, first time Porsche owner. Recently purchased a used 2002 base Boxster, 17" rims.

In the near future I will be looking at upgrades and preventive maintenance and I need advice on the best places for the best prices on quality parts. Im fine with OEM, used and refurb stuff. Dont have a mechanic yet but thought Id ask owners for advice first. Ill be needing things like a new shifter and boot (want the stock look), new "Boxster" trunk emblem, new aftermarket rims, passenger side wind guard (the honeycomb looking plastic insert). Plus, eventually, a new stock clutch, aftermarket air breather (or is it called a cold air intake?), new filters obviously....stuff like that. So, where do you get your parts? Do you insist on Porsche or do you do OEM? Thanks, any advice for a new owner is welcomed. I accepted higher maintenance costs is the price you pay for such a fun car but then I also like to ask around to see if Im spending too much before I start replacing things. Thanks.
