No!
The standard Honda filter for everything except the S2k, NSX and Insight is the PLM. These are made by Fram/Honeywell in the US market.
The standard S2k/NSX filter is the PCX, made by Toyo Ruki of Japan. It is larger then the PLM, but is a direct replacement. In fact, I use them in my FC and 3000GT.
The Insight uses a freakishly small filter made by Toyo Ruki. Forget about those.
