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 installation and removal. The 17 mm nut is crossed-drilled so racers can safety wire the filter to their bike.

Brilliant........ this K&N Oil Filter (KN-171B) has changed my life. The 17mm nut on the end of the canister has made removing the old filter at oil change so easy, even in confined spaces. No more useless filter straps Thank you K&N!

The only oil filter to use on my 02 Harley road king. User friendly and can't beat it.

Very good filter and fast service. The filter is easier to remove and install with the 17 mm built-in nut on the end..

I'll presume this filter works the same or better (K&N reputation) than the original but overall I'd rate it higher due to its design with the simple 17 mm nut feature allowing spanner or socket use.
