Filters are pre-oiled with Twin Air BIO Foam Filter Oil using our state-of-the-art filter oiling machines to provide the ultimate consistency in pore coverage. Genuine Twin Air Products. 2017 Husqvarna Enduro 701.
I changed the stock paper air filter to this foam air filter, installed a yoshimura r77 slip on and the Rottweiler fueling dongle and it made a noticeable difference in the power and throttle response. I put a thin layer of grease on the seal around the plastic before installing in the air box just to be sure no dirt or dust can get by and oiled the filters with pj1 filter oil. I like that these can be cleaned, oiled and reused so in the long run will save me money.
