The intake filter is easy to replace, and it offers good performance. These filters are actually meant to be cleaned, sprayed with a bit of filter oil (to keep the dust from passing through), and put back into service. As long as there are no holes in the filter after cleaning, keep using it.
The intake is basically the same design which was on the "Katana 265 Kit" which was sold by Sector 111 a few years back.
