Anyone know where to get a new O2 sensor for under what a Mazda dealer wants for one? They want $219.00 for one...

 

Your local auto parts store. $24.95. It's usually a Bosch.

 

Is this something that I ask for at the counter? Do I ask for one for a rx7?

 

Yeah, just tell them you need one for a 93-95 RX7. They should have it in stock. It's a fairly universal o2 sensor.

 

that is what i did^

 

Bosch Universal O2 Sensor

part number 11027

29.99 at most auto parts stores, just plug it in your precat and cut your existing o2 sensor wire, put it in the crimp connector and thats it.

I think they are charging 200+ because thats the o2 sensor with the connector. I think OEM uses NTK sensors

 

Thanks guys, and thanks BlackR1 for the part # that should really help me out. I'll check it out asap.

 

I got mine from rx7.com here is the link:
http://www.rx7.com/cgi-local/3catalog.cgi?cat=11&part=3

only $25. beats paying for the mazda one.

 

oopss, I thought you said fuel filter, well I also got one of there 02 sensor's for $40. Still waiting on the insatall though.

 

I payed 17.99 for mine.

Ask for Bosch universal single wire o2 sensor.

 

Are the Bosch any good? I want to replace mine but not with some POS. If they are descent then I will change mine out tomorrow. I need to just in case. I have never changed it before.

 

The Bosch is just as good as the expensive Mazda sensor. There is NO reason to spend the extra money. Remember, the only time the ecu uses the o2 sensor is when you are cruising, not at WOT.

 

I bought a OEM replacement from NAPA for like $110, but If I were to change it again I would buy a Bosch. Rather cut some wires than pay like tripple the price IMO.
