What Airfilter is better post your opinion

[reyes]

Can Somebody tell me what air filter is better for my 400ex k&n or uni?????? :devil:

[duke416ex]

I have always ran a k&n with an outerware.

[jak1389]

try a search. so much info on the topic;)

[2004400exa]

i have a uni in mine and i think its great and that just my opinion

[jak1389]

it all about the type of riding conditions you are in.

[Joe400ex]

my opinion is K@N ive had it in all of my quads it gives me great throttle response my two sense

[MR.BIG]

It depends on your riding conditions. The k&n is good but I would rather have the uni because it traps dust better than the k&n. I like both but foam traps dirt and dust a little better.

Is there anything wrong with stock?:confused:

[MR.BIG]

NO!

[FoxMxRiders]

I like Uni filter

[Out_Sider]

i like the amsoil powerfilter myself :) it provides the best filteration, but still flows like a uni or k&n

[Toadz400]

I've used stock, K&N and Uni and I will always use Uni on my machines.

uni uni uni uni uni uni!!!

[400exc]

i have a k&n with a outerwears air filter and it i awesome, it don let any dirt go through, or water, i recomend one to you

[wilkin250r]

I recommend UNI, though I run a K&N myself.

The K&N filter is real particular, you have to pay very close attention to oiling it properly, or else it WILL let dirt pass through. The UNI filter is much less critical, just slap some oil on it and go riding.

[cals400ex]

by the way, the UNI does come with its own cage and you do not use the stock one.

[400exrider26]

when you order the uni does it come with the cage? how do u just buy uni filters (just the actuall foam filter) without gettting the cage? u cant at all us the stock metal assembly from a 400ex?

[Joe400ex]

K&N i think is good my brothers bike has a unia nd it works very well

the uni comes with its own cage. it is less restrictive than the stock one. just lay the stock one on your shelf when you get the uni. the stock filter is shorter than the uni and the uni cage should be used with the uni filter.

[400exrider26]

how do you now the diffrence between if u are ordering a uni filter with the uni cage or just the actual filter?

[400exrider26]

anyone?

[jak1389]

when you call up the place you are ordering it from and ask.

[mills_racing]

welp i think the uni filters have the cage already in them when you order then ..mine did.

[Dave400ex]

The UNI filter comes with the screen. I believe mine was $26 from C&D. I use the No Toil filter Cleaner and Oil, this stuff works great!
