K&N powersports canister oil filters contain a modern synthetic filter media, designed for ultimate flow with less pressure drop, yet engineered for outstanding filtration. Engineered to support exceptionally high flow rates while providing outstanding protection from harmful engine contaminants, each filter is specifically designed to withstand the service intervals recommended by vehicle manufacturers. The heavy-duty canister is engineered to be exceptionally durable. Most of these have a 17 mm nut affixed onto the end that allows for easy removal. The 17 mm nut is crossed-drilled so racers can safety wire the filter to their bike.
