High quality
Size: 36mm
Perfect fit for my 2008 Audi TT oil filter cap. FYI, don't bother removing the plug in the cap if it is stripped. Mine was stripped by Audi mechanics and I thought it held the cap in place. It does not. I tried to loosen it with a chisel and broke the cap. An expensive, rookie mistake.

It's simply works
Liquid Molly engine flush simply works.. Put it F 150 and eco boost with the chain rattle. Followed the instructions. A week later they rattling stopped. Scene clean all the sludge out.
