Searching for intakes for my 2006 crv and finding little. However there’s much more options for the 2002-04 and I don’t get why they wouldn’t be the same... are they in fact the same and one meant for 2004 would be perfectly fine for my 06?

 

It's my understanding that 2002-2004 have mechanical throttle (cable) while 2005-2006 have a throttle-by-wire electronic system. The difference in throttle bodies and linkage probably explain the incompatibility.
