K&N's Wrench-Off oil filter uses pleated synthetic-blend filtration media to protect engines running synthetic, conventional, or blended oils while maintaining high flow. The heavy-duty canister includes a welded one-inch hex nut for easy removal, and where applicable an anti-drain back valve to prevent dry starts. Designed to meet typical manufacturer service intervals and backed by a one-year limited warranty.
