The K&N Wrench‑Off oil filter combines pleated synthetic‑blend filtration media and a heavy‑duty canister to provide high flow rates and contaminant protection for conventional, synthetic and blended oils. A one‑inch welded hex nut on the canister simplifies removal with a standard wrench, and many models include an anti‑drain back valve where applicable. Filters are built to meet recommended service intervals and carry a 1‑year limited warranty.
