Removing O2 Sensor
I'm getting ready to remove the stock exhaust system on my '02 KRS to install an aftermarket system (Two Bros) and I need to remove the O2 sensor first. Any suggestions on what tool to use to remove the sensor? Can I use a 7/8" wrench (7/8" corresponds pretty closely to the 22 mm flats on the sensor.) AutoZone sells a special socket to remove O2 sensors, but the BMW O2 sensor is really tall, and the AutoZone tool doesn't appear to be deep enough to allow the sensor wire to clear. Anyway, suggestions appreciated.
