Comments: Made in Japan by Toyo Roki Mfg., this is the current Honda OEM filter specified (worldwide?) for use in the S2000 only. It superseded the U.S.-spec 15400-P0H-305 in mid-2003. As reviewed by Road Rage at
http://forums.s2ki.com/forums/showthread.p...threadid=191911, this filter has good construction and good filter media. NOTE: As described
here, this filter appears to be identical to the HAMP filter.

Comments: Made in the U.S. by Filtech, this is the original OEM filter specified for the S2000
in the U.S. for MY00-MY03. It has been superseded by the 15400-PCX-004. As reviewed by marcucci at
http://www.ntpog.org/reviews/filters/old_filters.shtml, this filter has good construction, but the filter media is not great ("fuzziness" may be a concern for extended drain intervals). If you still have these lying around, there's no need to toss them.

Comments: Made in Canada by Fram, this is the original OEM filter specified for the S2000 (and most Honda cars)
in Canada for MY00-MY03. It has been superseded by the 15400-PCX-004 for the S2000, and by the 15400-PLM-A01 for other Honda cars. As reviewed by marcucci at
http://www.ntpog.org/reviews/filters/old_filters.shtml, this filter has mediocre construction and filter media, and is distinctly smaller than the U.S. and JDM filters. They were common in the U.S. as substitutes for the 15400-P0H-305 when dealer stock ran low. If you still have these lying around, use them on your Civic or toss them.
HAMP Synergy (model ??)
Recommended for the S2000? YES.

Comments: Made in Japan, marketed by Honda under the name HAMP (Honda Aftermarket Parts). Appears to be essentially identical to the 15400-PCX-004. As reviewed by marcucci at

Comments: Made in the U.S. by Filtech, this is the current universal Honda OEM filter specified for use in most Honda cars, but NOT the S2000. It is distinctly smaller than the U.S. and JDM S2000 filters.
Honda 15400-PLM-A02
Recommended for the S2000? NO.
Comments: Made in the U.S. by Fram, and probably equivalent to the Fram part #7317 pictured above, this was the universal Honda OEM filter specified for use in most Honda cars until mid-2003, but NOT the S2000. It is distinctly smaller than the U.S. and JDM S2000 filters, and was widely recognized as being a generally poor-to-mediocre filter.
