Made in Japan, marketed by Honda under the name HAMP (Honda Aftermarket Parts). Appears to be essentially identical to the Honda #15400-PCX-004.
The filter has good construction and a good filter media.
Loosening oil filter while driving
All Honda filters which are approved for the S2000 will have two metal contact rings with the gasket being between those two rings.
This dual ring construction is designed specifically for the S2000 to prevent the oil filter from loosening while driving due to the high vibrations of the high revving F20C engine.
Nearly all aftermarket oil filters to not feature that dual ring construction and there for should not be used.
However, this dual ring construction makes it nearly impossible to hand tighten the oil filter to the specified torque (24Nm / 18 lb-ft or 7/8 of a full turn of the filter).
This is why a proper filter socket is highly recommended.
Oil filter stopper
For additional security against a loosening oil filter while driving you can buy a simple tool often referred to as the "oil filter stopper".
It is easy to mount and basically just a metal strap around the oil filter that prevent the oil filter from turning and falling off.
