Review on 🔋 Efficient Brass Battery Sidepost Adaptor: Install Bay GM38 - Ideal for Installation by Roosevelt Weaver

Reliable product. Be careful not to undress like I've seen many others say. Factory 8mm and here 16mm. Huge difference in leverage achieved with a wrench. To update. Went for an oil change in the afternoon and found the end of the adapter had broken off. I assume it broke while driving. Examining the broken end piece, I noticed that the center looked like it was filled with concrete. Not sure what it is, but appears to be a cheap filler that may not be as conductive.
