Can someone confirm this is what I need to purchase for a second set of wheels if I want to leave my stock wheels/tires together? Tried searching and couldn’t find the answer:

You can check suncoast parts - get the part number from there then check the part number the ebayer is using.

Or call your local dealer’s parts counter.

 

Tried suncoast and it asks you for your vin. Don’t think it shows the part number since they’ll match to the correct one using vin.

 

The VIN is needed for the signal receivers in the chassis. There may have been minor changes based on VIN. Suncoast won't give out the part# online, OTOH I wouldn't buy off eBay if there is any uncertainty. You will need two items, the valve stem and the pressure monitor, for your new wheels. Here are the parts I bought from Suncoast for TPMS for my second set of wheels:

Thanks. I found the sensor part number off Tirerack for the Huf brand (which I believe is what is oem as well). Thanks for the links.

 

yep AFIAK they are Huf 433mhz I think...

 

I recently had these installed by dealer on my new wheels. Asked tech if they were fine and he said they are exact same unit as OEM Porsche. No issues whatsoever.
