This filter was original OEM on my 2013 Victory motorcycle with about 27,750 miles. I'd checked it one other time at about 15,000 miles and it looked OK. This time I was somewhat surprised by how dirty it got. Normally the air filter is something I check more often than this, but in the Victory 106 bikes, it's inconvenient to get to (seat, tank, side covers have to come off to get to the backstrap of the frame, which is where it's mounted). There was no discernible performance issues with the old filter, but I'm glad I replaced it. I figure I got my money's worth from it!
