As title says, for sale is a brand new 22641AA191 oxygen sensor.
Sensor was test fitted for 5 mins to check idle AFR corrections and then removed.
I bought this sensor to try to overcome my erratic AFR readings, but it did not work as the ECU of my 07 EDM STi was not able to read the wider current range that this sensor provides, so my AFR reading were pegged at 14.1 and could not go richer.
So my mistake is your chance to pick a bargain as these are ~350 GBP from any Subaru specialist, but now it can be your for only 200 GBP + shipping + paypal fees.
Last thing I need to mention is that to be able fit this to my car, I had to cut the wires of the sensor and fit my version of the O2 sensor connector. I obviously reverted everything back. wires are crimped and not soldered, and then heatshrink piped (if that is a verb).
