These oil filters contain a modern synthetic filter media designed for ultimate flow with less pressure drop, and are engineered for outstanding filtration. They feature a "spin-on" heavy-duty metal can with a 17mm nut affixed to the end, which allows for an easy installation and removal. The 17mm nut is cross-drilled, so racers can safely wire the filters to their bike. So, if you want excellent oil filtration for your bike, then these K&N oil filters are what you need.
