K&N powersports chrome canister 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, chrome-plated 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.

Bought for HD Road King. Easy selection. (really wanted black but they were all out, this works though). Good product design. Wrench flats make it super easy to change. No special tools needed for K&N oil filter. Thumbs Up

Great service, I like the easy installation with the bolt type attachment on the filter. A lot easier to fit than an OEM part so in all, a great bit of kit.
