I've been looking at the K&N XStream assemblies, looks like that one will flow a lot of air. I've also been looking to see if anyone is making a micro-screen filter like in some
oil filter applications
http://www.kandpengineering.com/tech...ghlights.shtml I imagine a micro-screen type would give the best possible flow, seems to be the least restrictive of any filtering element out there - I wouldn't recommend in dusty environments. I do intend to use the K&P replacement for the Moroso on my motor.
