Tried to replace the stillen g3 filters with these dryflows as recommended by stillen; however, the filters are not the same width and a support bar did not fit back after replacing the filters. So, I am returning these dryflow filters and just cleaning/oiling the k&n that came with the g3. It may be possible to not reinstall the support and therefore have the required clearance, but I didn't want to leave the support out.
