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.

I have used this KN-171C oil filter on my 08 Electraglide. It is a superior product. I will most definitely be using K&N filters on all of my vehicles from now on.

Filter is as described: chromed finish, is excellent and durable. Decent price and excellent shipping service.

Two positive features of this filter are 1: All chrome and 2: Socket nut on the end for easy removal. When you have a custom bike chrome is a nice feature. The nut on the end takes away the need for bulky tools to remove the filter. I've purchased K&N filters for my bike for many years and have had great results and performance.

Until I can purchase the reusable filter, this is the only one I use. Great product at a great price.
