Technical summary from MikeQBF of elementownersclub.com:
The felt-like polyester material which seals the ends of the pleating enough to prevent bypass. The base gasket is special to Honda. It is a half-round design, with a flat surface against the baseplate but a curved surface against the block. Another unique feature is a semi-labyrinth seal between the anti-drainback valve and the filter core - best seal of the bunch. The filter media from the rest, which appears to be more of a synthetic weave than a treated paper. It had the most filter area of our sample set - by far - at 151 square inches, the result of deep pleating. This is clearly the best filter when compared to these filters (Honda 15400-PLM-A02, Fram Extra, Bosch Premium, Mobil 1 M1 and the Amsoil SDF13) by an immense margin.
