NISSAN 16546-1LK0E Air Filter Element

The genuine NISSAN 16546-1LK0E air filter element (ELEMENT ASSY-AIR) is a key component of the internal combustion engine's air intake system. Its function is to mechanically filter incoming air before it reaches the intake manifold, preventing dust, soot, sand, and other solid abrasive particles from entering the combustion chamber. Proper airflow capacity and high filtration efficiency ensure optimal air-fuel mixture formation, protect the mass air flow (MAF) sensor, and safeguard cylinders, valves, and piston rings against premature abrasive wear.

Maintenance and Symptoms of Wear

A clogged or spent air filter restricts airflow to the combustion chambers, leading to several technical issues:

• Noticeable loss of engine power and sluggish acceleration
• Increased fuel consumption caused by an overly rich mixture
• Restricted engine sound and delayed throttle response
• Rough idle and potential air-fuel mixture fault codes logged in the engine control unit (ECU)

Replacing the air filter element in accordance with factory-recommended service intervals ensures long-term reliability and optimal engine performance.
