K&N Motorcycle Oil Filter KN-175 — High-Flow Heavy-Duty Filter with Welded 17mm Hex, Synthetic-Blend Media

K&N KN-175 is a high-flow, heavy-duty motorcycle oil filter that delivers durable filtration compatible with synthetic, petroleum, and blended oils.

Engineered for powersports bikes and designed to meet modern service intervals, the K&N KN-175 uses a synthetic-blend media to trap harmful contaminants while allowing excellent oil flow. The canister is constructed for strength and features a welded 17mm hex for faster removal, making maintenance easier for riders who demand reliable protection under real-world conditions.

How does the KN-175 help protect my engine?

The KN-175 uses a highly efficient synthetic-blend filtration medium that captures most engine-damaging particles while allowing oil to circulate freely. It is laboratory tested for capacity and burst strength, giving you confidence it will resist collapse or bypass under pressure.

• High-efficiency media captures metal shavings and soot
• Engineered to resist pressure-related failure
• Compatible with synthetic and conventional oils for versatile protection
