The K&N HP-3003 Premium Oil Filter is engineered to provide high oil flow rates and exceptional filtration for maximum engine protection. Constructed with a heavy-duty canister, this filter is built to handle high oil pressures while shielding internal components from harmful contaminants. The pleated synthetic-blend filtration media is optimized for use with all synthetic, conventional, and blended motor oils.

For professional-grade serviceability, K&N includes a 1-inch welded hex nut on the top of the filter, allowing for quick removal with a standard wrench. An integrated anti-drain back valve helps eliminate dry starts by keeping oil in the engine's upper galleys during shutdown.
