I like how its SO reputable that it doesn't even have a brand name... not even a fake one... at least take the time to come up with a creative name for it...
looks like a part from a leaf blower that he just installed the filter on... i think it would be better to just have the K&N airfilter minus that weird fan.... it probably constricts airflow more than anything else...
I wunder how many of those $10 leaf blower fans that guy has sold.... a nice profit in my opinion..
