InnotechRV TPMS Sensors - Aluminum (pack of 2)
**Important: These are not standard sensors. They are for use only on aluminum valve stems (which are rare). For standard sensors please see our other listings**
Some later model cars have aluminum valve stems in which case it is recommended that these sensors be used to avoid dissimilar metal corrosion.
Additional sensors can be added to the basic system to monitor up to a total of 22 wheels.
