A friend of mine in the US needs a new O2 sensor and was quoted $600 inc fitting. She has no idea how much it should cost and neither do I - does $600 seem about right or not?
No it doesn't! I don't know what a standard narrow-band O2 sensor costs but I paid about £150 for a wide-band sensor + gauge for tuning my AFRs. A narrow band sensor should be cheaper than that!
