anyone try them? are there any advantages over other filters (i.e. K&N, etc.)?

 

I personally dont know alot about it but alot and I do mean alot of the Locals here in Japan run that filter. Its probably because of ease of maintenance to change the filter itself. But I have no idea if its anybetter or not.

 

I have it on my car, it is like my 15th filter...i just replaced it with a new Greddy Airinx
