I dropped my Boxster off at
www.thespeedgallery.com to get the 60k mile service done. They're very cool there, did the service and also installed a K&N and perforated the airbox for me for a total of $988. Most other places were quoting upwards of $1200 for the 60k mile service alone. Anyway, the airbox perforation is crazy. Below 4000rpm, it's normal, but as soon as you peg that range with the pedal on the floor, it roars. Of course, it's not any faster, as expected, but it sounds really nice.
I may have them supercharge the car later this year. We had a nice discussion regarding exactly what we could do. I'm a salesman...I'm a business development manager...so I was expecting them to attempt to sell me something. To my surprise, they took the consultative approach. We orginally talked about a 996 engine swap, but they gave me the pros and the cons, and talked about how supercharging plus some other bolt-ons, could get close results for a lot less money. Really good shop, and I'd suggest stopping by if you are in the LA area.
