1995 Ford F150 Oxygen Sensor Replacement

My 1995 Ford F150 has (3) Oxygen or O2 sensors. One of them has thrown a check engine light, so I am replacing all of them. The upstream sensors Ford part # is F48F-9F472-AB and the Bosch replacement part # is 15717. The downstream sensor Ford part # is F4ZF-9G444-CB and the Bosch replacement part # is 15719. All you need is a 22mm wrench.
