nithinmike Posted July 9, 2015 Share Posted July 9, 2015 I just bought a used 1998 Legacy 2.2 5spd MT with ~169,000 miles on it. I'm looking for replacement knock and downstream O2 sensors for it. For the O2 Sensor, I am looking at the Bosch 15726. Is this a good sensor or should I go with the more expensive OEM part? For the knock sensor, I have not yet found a suitable part. Are there any non-OE parts or should I stick with OEM? Quote Link to comment Share on other sites More sharing options...
