            I agree with patrick on his statement. If you want a better filter than that check out AMSOIL Ea Air filters. they beat competitors hands down . AMSOIL filters 100 % @ 1.8 to 2 microns > , cellulose filters 40 % @ 1.8 to 2 microns, 5 micron or > only 90 % efficient , wet guaze like K& N and others 20% efficient @ 1.8 to 2 micron , only 80 % efficient @ 5 microns or > . Most dirt and trash end up in your engine through the air intake so the more that is caught the better . Feel free to contact us for any more info at www.lubedealer.com/parhamsynthetic
