K&N Oil Filters

K&N Oil Filters are designed to satisfy the needs of racers and engine builders as well as the average motorcycle or ATV owner who wants the best oil filter available. K&N Oil Filters trap harmful contaminants while the filter's construction allows for high oil flow rates.

The 'spin-on' oil filters feature a heavy-duty metal can. Most have 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.
