So dirt in the engine doesn't lead to scoring the cylinder walls or anything. It would also kind of work like sandblasting on the valves and seats, wouldn't it? I'm not saying that if you left your filter off for a week it would ruin the engine but over time, it would definitely have an effect if your filter didn't really stop much.
thats where the comparison is drawn, if you such sand into the intake then yes it will. but typical road dust, like silt, will go right through the car.. particles of dirt get through the filter anyhow. but one piece of anything can make it through the engine without damaging it. but its the size of the dirt and how much you allow in that will cause damage.Quote:

But... is better a bmc replacement filteror a K&n replacement filter??
that would ultimately be the buyers decision, the variation in design but have about the same flow.
