Good for removing stuck filter.

I have used it to remove old oil filter and it made death grip, which is good. But it really killed the filter canister, which is OK since I do not reuse it anyway. You can use this with various sizes of filters. When I installed a new oil filter, it dented and scratched canister a bit. You should be very careful not to tear canisters. I ended up buying a cheap wrench socket at Walmart so that I do not worry about damaging filters. I kept this to use for other purposes.
