I see that some of you don't like the way the K@N filter fits the 650.

So what other filters are out there?Do the flow as good?How do they fit?

I'd like to get a better flowing filter than stock that will fit well(If there's one out there)

 

I love UNI air filters. I personally feel they filter better with the two stage design, and they let air pass very well. Plus any foam filter oil can be used to clean and re-oil them. UNI Filters And they are only $21, so buy two and always have one ready.
