It's worth it if you plan to keep your bike for a long time. It's much more convenient than buying a new filter all the time. Just clean it, grease it and throw it back in. Unless you're doing serious upgrades don't buy one strictly for the hope of more power. Buy it because it is a added convenience and a high quality product.

Also consider a high performance foam filter that is also cleanable and last longer than the stock filter.

I don't have mine yet but I did order a K&N, like TXJ said I have always used K&N for the fact that they are high quality and reusable, the slightly better performance and increase in mpg (in my cars) is a bonus. Plus I was browsing amazon for the Factory Pro jet kit and I found the K&N drop in for ~$13 in their new warehouse depo? If I understand correctly, its stuff that people order and for some reason send back (wrong size? Or part#?) so I could not pas up the deal.
Also as a side note: I never open up/looked at the stock filter until after I ordered the K&N, but it looks a lot like some of the other aftermarket foam filters and it was heavily oiled so I would think you could wash and reoil the factory filter in the same way you would the other reusable aftermarket ones right? |

You won't notice any performance difference from stock with the K&N filter. The stock foam filter also probably does a better job of keeping dust, dirt and other unwanted particles out of your engine compared to the gauze type design of the K&N although the K&N will let more air through. Again, any performance gains from this is negligible. The K&N also does not fit perfectly like the OEM filter. It seems to stick out a bit. You have to really push and hold the cover while you screw it back on.

Earlier with the foam filter the bike used to reach around 140kmph really quick and after that it was a gradual climb. With the K&N it reaches 155kmph pretty fast and then the climb is slow. I may be wrong and this may just be psychological. Quote:
I've been concerned about the amount of dust filtered out by the K&N and other such aftermarket filters. There are many discussions on why K&N is good and also why its not. A lot of people claim that K&N and other such filters let dust to pass through which can harm the engine in the long run. Do you think i should go back to the stock foam filter? |

http://www.unifilter.com/online%20ca...tkawasaki.html The Pipercross filter carries a very good pedigree and they also have stats as to their effectiveness. One of their claims is that "Pipercross air filters consistently outperform paper and cotton-gauze rivals to supply air to the engine - even when dirty! This is thanks to the multilaminate construction used in every Pipercross performance air filter. Layers of varying porosity foam all work together to trap different sized particles." Fairly new to the States, they have the highest reputation overseas. Pipercross is also an Official partner for the 250 & 600 Ninja Trophy http://blog.pipercross.net/?p=304 and in partnership with Kawasaki Racing http://www.pipercross.net/motorcycle/products.asp http://www.ninja250forum.com/index.p...6&topic=3515.0 http://www.pipercross.net/motorcycle/ http://www.calsportbike.com/px/ |

thanks for the input guys.. im mainly looking to do it for increased power, maybe the best bet is just removing the airbox all together and doing the dual pod k&n, cause im sure thats what ill end up doing in the long run, might as well just do it and be done with it. unless theres not a huge difference from going that route to a good quality high flow filter?

JFC makes a solid air filter as well. I think it's around $45-50 and comparable to the K&N from what I hear.
