Seeking Stems and pressure sensors

[lurky]

Hello
I have a 2007 Boxster. For the last few years a local tire place has switched my snows/summer tires across one set of wheels in the spring/fall.
I got tired of the headache so I picked up a second set of wheels and I plan to switch them myself next time.
So now the summer tires are on the car and the winter tires are in the garage on the new wheels but there is a big hole where the stems should be.
I need to pick up both stems and the Porsche tire pressure sensors and I don’t know anything about stems.
-Can you use any stem with any tire or do I need specific ones?
-Where can I order the stems and the sensors?
-Can I attach the stems myself of does it require special tools?
Thanks!

The valve stems on your Boxster's TPMS is exclusive to that sensor brand only which is made by Huf.

The sensors are inside of the tire on the wheel barrel. Only the valve stems are exposed. You will need to have a tire shop do the installation for you.

Here's a link to a company that sells sensors for our cars at a good price. Talk to Jon.

He's a site sponsor on the Cayman board, so it's good to throw him some business.
