Works well
This works as a fancy oil cap remover. I wish my oil cap looked this nice.

Well built
Well made product. I have an volvo xc60 and it fits the oil filter housing perfectly but because of its thickness, there's some interference with the heat shield or it could be part of the skid plate assembly that is next to the filter housing.

Fast delivery and good quality part
Good quality snug fit. Works as should. Only issue I had was whe tightening oil cap back on the 18 ft-lb torque made this part slip. I used material to get a better grip and torqued slow but it still slip before the torque gauge read 18.5 No leaks! So it’s all good 😊
