questions about o2 sensor

Hi all,

I’ve purchased the o2 sensor:

I’ve got 2 questions about the sensor: … -1541.html

  1. Do I have to remove the white, paper-looking, thing at the top?
  2. On the Wiki page, I read that the sensor has a 48h startup time. Is this every time the sensor is turned on or just for the first time?

Thanks in advance.



1.There is no need to remove white paper like cover.
2.The 48hours is manufacturer recommended start-up time. (Every time the sensor is used)

Thanks and Warm Regards.
