Oxygen sensor ?

[BuckHunter]

Ok so I'm fixing to change my O2 sensors they have never been changed in 20 years. I'm not getting any codes its just going to be a maintenance thing. It has Bosch in it from the factory. Should I just go to the parts store and get Bosch or go with Motor Craft thoughts greatly appreciated.

Year+Model+Engin+Trans+... in your Thread\Profile\Signature\... will encourage folks to answer quicker.
Your profile notes 2002 Ranger, no other specs.
Likely got 2 or 3 OxSensors, depending on engine+exhaust.
Should be changed every 10yrs\100kMiles along with Plugs+Wires, to maintain power+mileage & not overheat CatCons.
All are 4WireNarrowBand with a Ford standard 4PinRoundConnector; only difference is Cable length.
Avoid cheap Asian offbrand OxSensors as they last a few months then die young; Bosch is Ford OE supplier, cheaper to order\buy Bosch.
A Bosch 15719 with 24i00 0m610 Long Cable+Plug is good to replace any Ford 4WireNarrowBand Sensor.
