i just got my K&N oil filter for my car today. i am actually impressed with the design. i usually buy OEM filters but i wanted to try this one and it looks identical to the OEM filter and it is made in germany also (stamped on the top). the one quality i like for the 104 filter is the inside is re-inforced more than the OEM so the pleats don't break down (turn brittle) and fold during long service intervals.
