Review on 🔧 Dorman 097-134 Copper Oil Drain Plug Gasket - Fits M12, Pack of 10: The Ultimate Oil Leak Prevention Solution by Justin Garrett

They fit my G37 (VQ37VHR) drain plug perfectly. I don't know if they will work as well as the shims sold at an Infiniti dealer parts department because I am not willing to pay Infiniti dealer parts prices for shims. What I can tell you is that I have never had any oil leak out of the drain plug during use. The first thing that screws onto the bolt, thread it up to the head of the bolt with the non-scored side facing the oil pan. I've done both with no leaks, but after reading a lot of forum posts I've come to the conclusion that more and more people think this is the way to go.
