Besides not having to oil, the media is thin and like I said, only one layer of it and is thinner than K&N so it doesn't restrict as much air...but who could tell the difference while riding. Race filter performance with street filter abilities, time will tell.
Supposed to filter a lot better as well which I will be checking in ....not sure now that I think about it...but for the cost I'm expecting the same cleanliness of my air box compared to the Piper Cross.
