I recently had a leak on my 2016 WRX at the tire shop. As usual, I had a valve stem cap from their cap basket that didn't fit. TPMS on the WRX and many Subaru's have a long valve stem cap (0.73") and the stock valve stem caps look weird as most of the threads are exposed. These caps are almost the same as the OEM caps with a few minor differences. Gasket inside like OEM Oddly enough there aren't many aftermarket offerings for valve stem caps this size.
