Hi
I just received a replacement downstream O2 sensor from Amazon for my T4R, and when I opened the package there was a tube, with Denso marked across it, and it has a gold colored liquid/paste in it. I am thinking this is to be applied to the threads when I install it.
The last O2 sensor (one I am replacing) I got a couple weeks ago did not have this tube of paste in it. Any idea on what this is, and what it is used for?
Thanks,
Michael
