I've previously bought the other Audi Huf Intellisens tpms sensor from this website for another car, that looks identical but isn't labelled OEM, and is about a third of the price ($23). Those came as a pack of 4 sensors for said price. So I was certainly surprised when I received this one in the mail and it was only a single sensor, for $70, meaning that this is not just 3x the price, it's 12x the price.
Sold as single sensor/stem, unlike others on this
