Where To Buy The O2 Sensors And Save $$$

You could run down to your neighborhood auto parts store and buy the oxygen sensors you need there, but you'll likely pay twice as much than online.

If you need/want to save some money check out what the oxygen sensor costs at your local auto parts store and then check out the price of the same sensor here (you'll see the difference):

This O2 sensor is a downstream (after catalytic converter) sensor that fits 2.2L, 2.4L, 3.1L, etc.

This O2 sensor is a upstream (before catalytic converter) sensor that fits 3.1L, 5.7L etc.

This O2 sensor is a downstream (after catalytic converter) sensor that fits 5.7L, etc.

If you aren't sure if these oxygen sensors fit your specific vehicle or not (or it's not listed above), click on the O2 sensor and once you're there (at the site), you can cross reference your vehicle's info on their handy parts look up index.
