do uni air filters add power to atvs cus i might get one fo my 400ex for power please respond now im orderin tomorrow k thanks

I would go with a K&N Filter. They last for a long time before cleaning and is able to suck alot of air.

how long do i have to clean them like once a day or once a week thanks

[AtvRider21]

if u ride in dust GET UNI!! k&n is good for sand but i would not trust it with dust

[Juggalo]

yeah uni for dust k&n for sand. you clean a uni as much as you would clean your stock filter.

UnI just suck if u get a foam filter get a twin air.But u could get a K&N.Outer wears only take 5-10% air flow away but u are not gonna feel half hp.
