K&N High Performance Oil Filter - KN-164

The K&N KN-164 is a premium spin-on oil filter specifically engineered for high-performance applications, most notably for BMW motorcycles. It’s popular among riders who want a balance of high flow rates and rigorous filtration.

 

Key Specifications & Features

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

   

• Anti-Drainback Valve: Equipped with a rubber anti-drainback valve to prevent "dry starts" by keeping oil in the filter when the engine is off.

   

• Construction: Features a heavy-duty metal canister for increased durability against debris or high internal pressure.

   

• Nut Attachment: Unlike many OEM filters, the KN-164 typically features a 17mm cross-drilled nut on the top, making removal extremely easy with standard tools (and allowing for safety wire attachment for racing).

Tip: While this filter fits many BMWs, always double-check your specific year and sub-model using a fitment guide, as BMW transitioned filter sizes across different engine generations.
