Well for one, it addresses the loose air filter connection that plagues bikes with the factory air boxes, which allows dust/dirt to bypass the factory air filter and contaminate the engine. Not all bikes seem to have this issue, mine did. I have been running a napa gold(will have to look to find the part#) paper filter that makes a much better connection with the rubber neck stack sticks out into the air box, but at higher work loads it feels as if my bikes is struggling with power from the paper filter, like it can't get enough air. So I am going to give this a trial and see how it works out. I did the calculations and I believe I found a uni filter that will work perfectly with the hvac duct mount I ordered from Amazon. If I can fix this reliably fix this issue I'm suspecting one would gain increased engine life and a small bit of power at an affordable price.
