Heated or not?

[Payback45]

I need new O2 sensors and I need to know if I have heated or non heated. How do I find this out? I have a 02 Legacy USDM BE

Do you guys also know if I have 4, 5, 6 wires on either of them? I would check my self but I have no way of getting under my car. Also, do you guys recommend a particular brand ?

I recommend OEM sensors.
