  • O/E replacement oil filters for most cars, trucks, SUV's, motorcycles, & ATV's
  • 17 mm exposed nut designed for easy oil filter removal
  • Heavy duty construction for extreme conditions
  • Anti-drain back valve (where applicable) eliminates dry starts, prevents oil from draining back into crankcase during engine shutdown
K&N powersports oil filters contain a modern synthetic filter media, designed for ultimate flow with less pressure drop, yet engineered for outstanding filtration. K&N powersports 'spin-on' oil filters feature a heavy-duty metal can. Most of these have a 17 mm nut affixed onto the end that allows for easy removal. The 17 mm nut is crossed-drilled so racers can safety wire the filter to their bike.

Nice to have a nut on the end for removal. Hopefully the filter will last as long as the oil will.
