Went to rice err PEP boys and asked for an O2 sensor for a GT Mustang to replace the OEM one.

Wow, good looking sensor by Bosche. Much larger than the OEM Fd one. It has four wires and is about $60.

Can I use this O2 sensor....? If so, I think it has four wires:

2white
1 grey
1 black

Anyone using this sensor? Think it is preheated? How is it coonected? Which wire is the actual sensor to clip the oem plastic connector too?

TIA!

Damn y'all...not one reply?

Looking for alternatives to the oem sensor with a heated one.

You can buy a Bosch O2 sensor for the FD for $30.00
Its the same exact O2 sensor Mazda sells for over $200

I think you can.

usually 4 wire sensor is better then single wirw sensor.
because it's heated and it has seperate ground wire.
I think grey wire is sensor wire and balck is ground and white ones are for heater.

This O2 sensor is before the cat....just thinking of alternatives...really nice sensor comes with antiseize and plastic cap over the threads. Thanks for the feedback everyone!
