Interesting that the Carquest 85365 fits - that's the same filter most Nissan cars take (just installed one on an Infiniti G37x today, in fact). Glad to know that, because it's way cheaper than the Yamaha one (like $3 vs $30) and there's a Carquest right here in my suburb. Carquest filters are made by Wix, or were, anyway. I've heard Mann has started making their filters, which is also good. We use Mann filters exclusively at the European specialty shop I work at (used a Carquest filter for the Infiniti because we don't do many Japanese cars so we don't stock filters for them)
