I need both before & after cat o2 sensors

What's a good price?
What's a good brand?

What should I avoid?
 
Cool, Turbo&Auto
those are the 4 wire universal, right? How'd you do it? Was it difficult to wire in?

OEM runs $250 from honda, & a bit more or less for other OEM plugged ones.

Anyone got anything to say on Walker o2 sensor?
 
I used a ohm meter and measured for the heater +, 12v, and then the 2 gnd wires. Process of elimination and you have the signal wire.
 
the idea makes sense to me ... dumb question, what am I measuring, resistance, correct.
I'll get some help on it but still tell me anyway, please?
