Yes, they are from iForged and they will fit Ray's wheels that have right angle valvestems. Unmounting the tires, installing the adaptors, balancing was free bacause someone owed me a favor. But I asked around here and it should cost no more than $25 a wheel to install and an hour of your time. The only thing I paid for is $6 a tire for nitrogen. FYI, I'm still using the stock TPMS. Best of all, TPMS is now fully functional and I didn't have to get those metal bands or drill a hole.

you need all four of them....
