K&N Motorcycle Oil Filter KN-163 for BMW Models — Wrench-Off Nut, High-Flow Synthetic

Built for powersports engines that demand reliable oil circulation and durable filtration, the KN-163 pairs high-efficiency synthetic media with heavy-duty construction to help preserve engine life and simplify maintenance. It’s engineered as a direct factory replacement for many BMW models and optimized for use with synthetic and conventional oils.

How does the KN-163 improve engine protection?

The KN-163 uses premium synthetic filter media with uniform pleats to capture contaminants while preserving oil flow. That balance of filtration efficiency and capacity means the filter resists clogging under typical riding conditions and helps maintain consistent lubrication.

• Premium synthetic, high-efficiency media captures fine particles.
• Uniform pleat design increases surface area and dirt-holding capacity.
• Laboratory-tested for capacity and burst strength to withstand real-world stresses.

Will this filter make oil changes faster and easier?

Yes — the KN-163 includes an integrated welded nut on the canister that accepts a wrench, letting you remove the filter quickly and cleanly without fumbling small tools. That feature reduces changeover time, particularly useful when working in tight spaces or on the roadside.

• Welded wrench-off nut for quick, tool-friendly removal.
• Stamped to match OE dimensions for straightforward installation.
• Designed to be a direct fit for many BMW powersports applications.

How long can I expect this filter to last, and what oils are compatible?

The KN-163 is engineered for long service intervals and, when used with recommended maintenance practices, offers protection up to 20,000 miles under appropriate conditions. It’s compatible with premium synthetic, conventional, and blended oils and includes a part-specific bypass/pressure relief valve tuned for modern oil formulations.

• Long-life design rated for up to 20,000 miles in suitable use cases.
• Compatible with synthetic, conventional, and blended motor oils.
• Part-number-specific bypass/relief valve optimized for oil pressure control.
