they wil working alright. but would recommend to change if more than 10 yrs or 100kms.
shouldn't cost too much and can get from repco or supercheap.
they are borch oem replacing. make sure dun mess up with one wire or 4 wires.
I've worked on a 92 NSX with custom exhausts (although heaps cheap looking) and the Bosch aftermarket HO2S's were causing the engine light to stay on. Don't get me wrong, Bosch does make great products. Honestly I believe the way they were wired was the problem. Just be careful who makes the connecters and make sure they are secure.
That argument can go on forever but if you changed it,I would bet there would be benefits. i.e. it would read more accurately.
Absolutely -- The role of the 02 sensor is understated. Often an 02 sensor is faulty without actually throwing a CEL Code. This is because the voltage is sensitive & minor malfunctioning of the Sensor will still output a voltage, just incorrect leading to (usually) over-rich condition. This can reduce fuel consumption in our cars (esp when they have had it or are on their last legs) to as bad as 300kms a tank. Even less in some cases (such as mine lol).
Bottom line -- If you have the $100 then do it, and reset your ECU so it can re-trim itself over time. And post up the item you used.
There was reference above to not using single wire or 4 wire, can someone enlighten me?? The dick that replaced mine originally (worked for around 2 days) put a universal Falcon AU sensor in it (4 wire) and now that the harness / connector is gone I have had difficulty in connecting it all.
I know:
1 wire is 02 Sensor Power
1 wire is Voltage Output
1 wire is O2 Heater
Is that right? Hmm .. Also problem with bloody 02 sensor placement being on underside of extractors means its prone to being hit / bumped. Why the didn't install them pointing out the side I'll never now.
