A programmable sensor such as the Ritesensor is the best option for the Subaru range as the Legacy has been fitted with a variety of OE sensors from Schrader between 2008 and 2021, so it is very easy to fit the wrong replacement sensor as they all have different specifications. A tool such as a TECH600Pro will identify the correct specification of part and program a sensor, such as Ritesensor, to replace ensuring correct functionality.
