Proceed with caution on this advice Rod.  If you get the oem bosch O2 sensor
for the urs4/6 (Bosch 13019), it should come with a protective plastic cap
and a tiny dab of A/S already on the threads.  The reason for this is that if
ANY A/S gets onto the probe, bye bye O2.  I also advise that one be very
careful in the insert procedure of the 02, it's really not that hard to
scrape the probe against the threads when putting the 02 in.  Also, when
removing the plastic cap, make sure the land with the A/S on it doesn't touch
the probe, btdt.  If it does, use a rag with some silicone fee brake cleaner
on it to wipe off the A/S.

Also, make sure the A/S is NOT on the washer land area, it's not meant to be,
and can affect 02 output.

I use a 22mm box end. Disconnect the sensor on the firewall dont forget to
unclip both, then feed the 2 sensor ends thru the box and go to town. I find
the boxed end makes it easier than regular end. Reverse to put new in. This
is a good application for  SHOULD I SAY IT Antiseize.
