Show original supplier description

The Feuling KN-171B is a black, spin-on style performance oil filter engineered to keep your engine's oil clean and protect against wear particles. It utilizes a highly efficient synthetic-blend filtration media that works with synthetic, petroleum-based, and blended oils, including high concentrations of synthetic racing oils. This design ensures high flow rates while effectively filtering contaminants. Constructed for durability, the KN-171B features a heavy-duty canister, a double-rolled seal, and a pre-lubed base gasket. For convenience, it includes a 17mm welded hex nut for easy on and off wrench removal. The filter also incorporates an anti-drain back valve to prevent drain-back and dry starts, and a bypass valve for consistent oil flow. This K&N oil filter is designed to meet or exceed the service intervals recommended by vehicle manufacturers and is protected by a 1-year limited warranty. It is important to confirm fitment for your specific motorcycle model. The item is noted to fit select Harley-Davidson Motorcycles, including Twin Cam '99-'17 and M8 '17-'26 models. It does not fit a 2014 Ski-Doo Grand Touring 600 E-TEC LE.
