I purchased this filter for my 2000 Kawasaki EX-250. It fit perfectly and was easy to install. It makes an awesome intake sound now but it's still a 250 so it is as slow as ever I am definitley considering the same mod for my 1999 EX-250.

Although this filter was not the one K&N recommended, it is the one that fits my Kawasaki Ninja 2004 perfectly. I've never had a problem with a K&N filter. You guys rock!
