Yep. Came across the same thing myself a while back. Contacted K&N filters directly as they had a 303 and a 204 listed for the SP. Exchanged several emails with a Don Marshall (Technical/Sales Executive) at K&N Filters Europe.
The answer, from "the horses mouth" so to speak was that the KN-303 was the correct fitment for a 2000 SP-Y and the KN-204 was the correct one for the SP-1.
Copies of email conversations.......
Hi there, just a quick question. I have been looking at your oil filters for a 2000 HONDA SP-1. I am a bit confused as to why there are two part numbers relating to this application, namely KN-204 and KN-303. Can you tell me what the difference is between these two filters and which in fact is the correct one for the bike.
Thanking you in anticipation.
Cheers

http://www.knfilters.co.uk/search/appli ... rod=KN-303 But only on the filter cross reference for the KN-204 does it list it as a direct replacement for Honda part 15419-MCJ-505
Cheers.

Hi
KN-303 is suited to the 2000 manufactured model and KN-204 to the 2001-2002 mode.
