Query: Great oil filter

This is by far one of the best oil filters on the market. The studies I've read about synthetic media filter shows that they filter exceptionally well. You can actually feel the quality of this filter when you handle it. It is sturdy and hefty. The weight of the filter gives about the amount of filter material available. And one bonus that I love is the nut, which makes removes a snap.
