Ok...anyway--both are pretty equal when it comes to performance. THe K&N offer an exposed conical filter where Volant has a conical filter retained in a box that pulls air from the passenger side fender (like stock) and from a hole in the bottom of the Volant box. Volant also offers their VaraRam system that allows you to hook up a ram air style tube that runs from the bottom hole of the filter box to the opening for the tow hooks on your lower valence... The K&N doesn't offer that.
