wanna know if anyone here is running a pre-filter. often times known as filter skins, I know, air-raid and k&n make them. they slip on over your cone filter to pre-filter out the big stuff. i have one on my quad, and it makes a HUGE diff in the service interval. figured it would make sense considering the filter on my car is like 4 inches above the ground. anyone know where to get one for a k&n the size that is on my car?
