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.

Fast delivery. Chrome finish is a plus. The external socket fitting will make an easy removal on my next oil change. I trust the engineering K & N designs into their products to filter out contaminates to protect my 2006 Harley Davidson 35th Anniversary superglide motorcycle.
