Nah, I know simple filter upgrades rarely net anything more than a few "butt dyno" HP and a slightly different sound. I'm mostly looking for something that's at least as good as stock but cleanable/reusable. Amsoil and AEM both offer reusable dry filters, but apparently not for the VX. I'm not convinced that they don't sell products that would fit though, but unfortunately their sites don't seem to have a page that lists dimensions for all their filters.
