What is the cost to replace the O2 front sensor in a 2005 Impreza RS 2.5L? on 2005 Subaru Impreza

Will Subaru reimburse for this cost? I've replaced twice now in 125k miles. What is the expected cost to replace? Also had a transmission linkage problem. Cost me $500.

o2 sensors are sold everywhere the cheaper ones don't last. use dealer parts only. aftermarket parts are mode to fit multiple vehicle and don't meet specific specs
