Is there any advantage to using a tapered filter as opposed to a straight filter?

Straight:


Tapered:


I ask, because most products use a tapered filter, when it would seem straight would be better...

In most cases, you'd want to use the biggest filter (within reason) that you can fit. FocusSport agrees with this philosophy. The Cool-Flo for the Zetec, for example, doesn't have much room for a huge filter, so we use the tapered cone for proper clearance.

Nothing wrong with that, unless it's a wall of fire.
Seriously, it's the same logic as using the largest filter you can fit, more surface area. No point in using a filter that can't breathe from the face. I don't know why K&N still sells such a piece.
