Both filters come up in a search, but no one has compared the two on this forum.
K&N's website says to use KN-148 for Gen 1 and II and KN-204 for Gen III
As I understand it, nothing was changed between the generations what would require using a different filter.
I just installed the KN-148 on my Gen III yesterday and all seems to be fine. I like the idea of having a bigger filter, thinking that it's going to have more filtering media inside.
Anyone care to chime in as to why K&N recommends two different filters for our bikes?
Some some comparison pictures.
