K&N powersports oil filters are ‘TUV’ product endorsed
& ‘TUV’ factory production monitored.  This means every
K&N oil filter is equal to or will exceed OEM specifications.
K&N filters contain a modern synthetic filter media, designed
for ultimate flow with less pressure drop, yet engineered for
outstanding filtration to meet or exceed OEM specifications. 
K&N powersports ‘wrench-on’ oil filters feature a heavy-duty
metal can with a 17mm nut affixed onto the end that allows
for easy installation and removal. The 17mm nut is cross-
drilled so racers can safety wire the filter to their bike.
