so I need an airbox kit for my banshee.. I have a choice of the uni style foam filters, which I tend to dislike. cleaning them is a PITA and they dont seem as durable as a K&N.. I have had K&Ns on my trucks and they are a breeze to clean, and seem to trap dirt well...

which one do you choose for performance, durability, & effectiveness?

the service manager at the yamaha shop told me the k&n's might give a little more performance but even with the outterwear, the uni foam will trap dirt better..

the bike in question is a 03 banshee.. will be ridden in dirt and sand

in my testing, the factory filter was always faster than my k+n. no matter how it was jetted or lid/no lid. i'll sell it too. 25$

I would go with K&N and get the outerwear on it. True you will get more performance out of it.

Also K&N run a little longer then foam when it dirty. Also easily to clean too.

 

The only choice for me is foam. My dirtbikes have all come with it, and every quad I have owned has had an upgraded foam filter. I trust them to trap the dirt better than the paper/cotton type. My YZ's and the CR's I have seen have all used foam filters. Those high compression, low tolerance motors really depend on clean air.

Since I already have to clean the foam filters on the bikes, it makes sense to clean the filters on the quads too.
