A K/N oiled filter with outwears just can’t be beat imho. Stock filters work but get expensive (after a while they are spent and need replacement) ... Max flo oiled foam filters are a significant upgrade and a guy can get 25+ tanks before needing to be cleaned and re-oiled lest “fines” start working their way into the engine. I’ve got 100+ tanks on the K/N with outerwears without any debris getting into the intake. A machined intake / velocity stack is needed and the filter will protrude out the rear of the saw a bit (some guys do not like that) but if used for bucking / noodling I haven’t had any issues.
