yeah any OBDII scanner will work. Some of the nicer ones will tell you what the code corresponds to. SOme only tell you the code itself. The yellow Actrons seem to be the most popular. This one guy who checked my car once was a mechanic and had a really deluxe one that had very detailed info concerning the CEL code.
NIce to have and you can use it on all your future cars unless they go into OBD III

You can get all the codes specific to Boxsters by model year on TooPants' Renntech.org
The same CEL code can mean different things to Boxsters from different model years. I found this out when I had to replace my throttle body.
