If you are after max power then there are probably better choices BUT if you are after keeping dirt out of your engine. Most specifically the super fine talcum powder that I frequent in the desert (and you see in baja) then nothing will beat the Volant with Donaldson powercore filter. Which is what I run.
I have been running the powercore filters on other equipment for 20 years and I never ever seen any dirt past the filter. While I have seen many many engines damaged by dirt running other filters, in the same conditions.
