Louvers look good.Acsent proved with 4548-12 testing that the Boss spec sheet is correct. It’s always been a rock catcher just like the Wix XP. I’m not paying a premium price for OEM efficiency and choked louvers with a cut ADBV.
M+H has destroyed two iconic US filter companies. I used Wix for over 20 years and watched M+H turn them into. Those NC boys were proud craftsman at one time but those days are long gone. I will not support M+H.
