I was looking at the Alba Z400 K&N kit which has a new adapter and the filter about 2 months ago when no one else had anything out. Is this still the best setup right now for a K&N system?

 

That is the set up I use and am very happy with it. It works just as good as the K&N's I have on my other quads. I mainly ride dunes that is why I chose the K&N. I saw the complete setup on ebay for $75.

 

It seems to work well on mine. There are other adaptors but, they all seem to be about the same price. Putting this on, a pipe and jetting - wow. It feels very strong. I would like to find a raptor to measure it against because it feels a lot like that kind of power.
