K&N High Performance Oil Filter for Harley Davidson Iron 883/ Forty Eight 1200 - KN-170

K&N High-Performance Oil Filter | Harley-Davidson Sportster (KN-170)

The KN-170 is the premium filtration standard for the Harley-Davidson Evolution (Evo) 883cc and 1200cc engines. Whether you are riding an Iron 883, Forty-Eight, Seventy-Two, or a Nightster, this filter is engineered to handle the unique demands of an air-cooled V-Twin, providing superior protection against the high heat and vibration levels these bikes generate.

Key Features

• Evo-Specific Engineering: Designed to meet or exceed the flow requirements of the Sportster's oiling system. It ensures that critical engine components, like the hydraulic lifters and rocker arms, receive a steady supply of clean oil.

• The Signature 17mm Nut: Features K&N’s famous welded hex nut on the end of the canister. This makes oil changes a breeze, allowing for easy removal with a standard 17mm wrench or socket—no specialized oil filter claw required.

• Heavy-Duty Canister: Built with thicker side walls than standard filters to provide extra burst strength and protection against road debris kicked up by the front tire.

• Advanced Filtration Media: Uses a high-performance synthetic-blend media designed to trap 99% of harmful contaminants while maintaining excellent oil flow rates.

• Safety First: The 17mm nut is cross-drilled, allowing you to easily attach a safety wire—a requirement for many track days and a great "peace of mind" feature for long-distance touring.

Why Choose K&N for your Sportster?

Air-cooled engines like the one in your Iron 883 or Forty-Eight rely heavily on oil not just for lubrication, but for cooling. The KN-170 ensures that oil flow is never restricted by a "collapsed" or clogged filter element. Its heavy-duty construction is specifically suited for the high-vibration environment of the rubber-mounted Evolution engine, ensuring the filter stays secure and leak-free between service intervals.
