I tryed every possible way w/K&N ,way too much dirt in intake boot, just look around at top engine builders, most use foam, Uni is a good choice............a little dirt goes a long way inside a motor ,kinda having a superfine grit sanding compound inside your motor........NOT.........Uni with a good synthetic oil spray to keep out the "devil" in your motor......this comment will stir it up with some but........... been there done that ,stand my ground,

twin-air or uni without a doubt I dont trust gauze filters on an offroad machine I can see using one on a car or truck but not a machine that spends most of its time in the dirt,mud or sand.

TwinAir:D They are awsome

is the white brother's power filter any good!!

Has anyone tried one of the Twin Air power flow kits? I was looking into buying one for my EX but would like a little input. I does away with the stock backfire screen and replaces it with a new filter cage. The inside of the filter has a backfire resistant foam.

I put a TwinAir powerflow kit on my 440ex. It is AWESOME. It comes with a new cage. The cage bolts to the Air box and is sealed with an o-ring to prevent air leakage from around the filter. The filter it self is bigger too. Twice the size of stock.

I've been interested in giving Sparks air filter a chance, everything else Curtis makes is awesome so I'm sure his filter is too.

Pretty much all foam filters offer good protection for your motor. I ran two K&N's in the past and both passed fine dirt no matter what I did. I use a UNI now with no problems :cool:
