How do these filters improve engine and cabin performance?

The engine air filter traps dust and debris before they reach the intake, preserving throttle response and component life. The cabin filter’s multi-layer media and activated carbon reduce odors and capture finer particles, improving the air you breathe inside the vehicle.

• Engine filter: high-flow pleated media for effective debris capture
• Cabin filter: multi-layer including activated carbon for odor control
• Both designed to maintain OEM airflow characteristics

• Direct-fit to vehicle housings—no trimming required
• Compatible with original mounting points and seals

How do I confirm the correct part before buying?

Compare the vehicle’s current filter part numbers against the replacement references and verify your vehicle’s year, make, and engine size. Consult your owner’s manual or existing filter housing label for part numbers to ensure a precise match.

• Match OEM codes like 16546-1LA0A, 27277-EG000, CF10743, and others listed
• Confirm vehicle: Nissan Armada 2017–2024 or Infiniti QX56/QX80 years indicated
