I have a 2010 vision 8 ball. I am looking to buy the Arlen Ness twin sucker front filter. I noticed when I zoomed in on the picture that the part # 7081395 was at the bottom of the filter. I then went to Victory Parts R Us and found the OEM air filter with the same part number. Why is the Ness filter 53.99 and the Victory Parts R Us filter 19.20?
