Which is the best I do not know.But I can say I have the K&N on mine and it has been good to me but it was on the truck when I bought it.Apperently it didn't give enough of an increase on fuel economy to the previous owner because he traded it in on a Chevy Cobalt
.I don't know if I would run a K&N in real dusty conditions though.I have had issues with them on my Quad letting dirt through into the carbs even with a pre filter.
