Rear Oxygen Sensors? Which ones...

[JerZeyStangz]

My rear oxygen sensors are toast and they need to be replaced. I was just wondering where is the best place to purchase them and which ones to get? Alot of people recommend staying with OEM (Ford) or going with Bosch (which they make like oem). I heard that they are both great but some people like to stick to the brand for a lot of reasons. What do you guys think? :dontknow:

You should use ONLY Ford OEM O2 sensors.

I don't have personal verification of that. What I can tell you is that the OEM sensors look a little different than the aftermarket Bosch ones. Both my dyno shop and one of the best independent EFI tuners here in Phoenix told me never EVER use aftermarket O2s. Ever. Everever.

I've notice when I got my car 3yrs ago that it ran the best on the original sensors and got the best gas mileage...
