To replace Bank 1 Sensor 1 (the upstream oxygen sensor) on a Subaru Legacy, first, ensure the engine is cool and disconnect the battery. Locate the sensor on the exhaust manifold, then use a suitable oxygen sensor socket or wrench to unscrew it. Install the new sensor by threading it in by hand, then tighten it securely without over-torquing. Finally, reconnect the battery and clear any diagnostic trouble codes if necessary.
