              So even with my stage 1 K&N and stage 2 DNA fitted, these holes would make a difference in air stream i guess ???
              Cause i have a few left of my previous side panel conversion and without the little filter they would come in handy then........

         Kev is there any advantage to air intake to drill the holes even when i have stage 1&2 dna filters and would it do any harm if i did?
