If you're definitely replacing them, don't bother buying the special socket with the cutout to fit the wiring harness through. Those sockets tend to flex at the cutout and can strip the O2 sensor.
Instead, just cut the wiring off at the end of the sensor and find a deep socket impact that fits (7/8 in. or 22mm) and use a breaker bar or an impact drill.
Use never seize on the new sensors and a wrench to tighten.
BTW, the upstream O2 sensors (between the engine and catalytic converters) are the important ones. The computer uses info from these to adjust the mixture correctly. The downstream sensors only monitor the catalytic converter efficiency and doesn't effect performance.
