Review on K N PS 7040 Oil Filter by Jim Acquista

K&N makes the best filters in my opinion. This is for my wife's Mercedes. You can see with its open media style that the elements are more unified and stable. The frame is even slightly stronger than the Wix style I've bought in the past. I'm sure there are some website or web bloggers out there who will tell me this is different than any test, but I can feel the difference and it says a lot. If they take the time to add that the difference in material weight is for a reason. I also use them on my Duramax!
