I like Tempest products; spark plugs and oil filters with a magnet. Unfortunately, I had a recent issue with their oil filter, trying to get the darn thing off. They have a 1" nut to facilitate removal. Unfortunately, they paint it. When trying to get it off the plane my socket would not fully engage the nut because of the paint. The paint also seems to serve as a lubricant to help it slip. It turned out to be an exasperating ordeal. I suggest that the paint be removed from the nut before installation. The socket fits much better and shouldn't be a problem next time.
