4200 miles of use on Triumph Tiger 800. ADBV and gasket were still very pliable. Filter media intact with strong construction. Put on a brand new one and will buy more in the future. Seems to be a very solid option.
I just told a friend to order a HF303 for his "new" bike based on what I heard about HiFlo Filtro - and the gasket looks like the P-type O-ring used on Japanese OEM filters.
It doesn't look like a Toyoda Boshoku/Denso filter but it does look like the generic Malaysian-made Union Sangyo filters sold by Beck-Arnley years ago.
