No pouch, no anti-seize, no special handling instructions, no identifying information/specifications and no instructions. This is a non-standard product.

I also warmed the car up to operating temperature before attempting the removal. I used an ARES 70039 O2 head offset 3/8" x 7/8" (22mm). Other buyers mentioned that their part arrived "used". To me it looks…
