I can give you a specific example where a K&N cone filter is a significant improvement over a stock factory airbox.
1985 and older Buick Grand National/T-type turbos. The factory airbox simply cannot flow the kind of air required when you make just a couple modifications to the vehicle.
What's more, a K&N facilitate the use of aftermarket cold air induction systems, which do make a difference.
So, while they are to a large degree marketing creations, K&N's (or more specifically, large cones) have their place.
