Yes these are the newer continental sensors. You have a deal at $150. Hopefully PayPal friends and family will work for you. My PayPal email is [email protected]. Please send me the shipping address and these will ship tomorrow once payment is received.
I am not a model 3 expert, but these sensors work on continental tpms systems. The model S switched from a different system to the continental system sometime in 2015. I would suspect that they have used the same system ever since on all their vehicles including the S and X. Hopefully you can do a bit of research about the model 3 and confirm it uses the continental tpms system. Lots of cars use that not just Teslas.
