Kefly Engine & Cabin Air Filter Kit for Nissan Sentra 2020–2025 2.0L — Direct Fit, High-Permeability Media

This Kefly kit includes a direct-fit engine air filter and cabin air filter engineered for 2020–2025 Nissan Sentra 2.0L models to help maintain engine breathing and cleaner interior airflow.

If you drive a 2020–2025 Nissan Sentra with the 2.0L L4 petrol engine, routine air filtration upkeep keeps the car running smoothly and the cabin more pleasant. The Kefly two-piece set replaces the factory engine and cabin elements with high-permeability media designed for straightforward, periodic swaps—recommended at about every 12 months or 12,000 miles under normal use.

How will these filters affect engine performance?

The engine air filter in this kit helps the engine draw cleaner air, which supports consistent combustion and reduces abrasive particles that can cause wear. Improved filtration does not change engine tuning, but it preserves designed performance and efficiency over time.

• Direct replacement for OEM 16546-6LA0A / PA99575 for accurate fit.
• High-permeability filter media for steady airflow to the intake.
• Reduces dust and debris entering the intake system to limit wear.

What benefits does the cabin filter provide for passengers?

The cabin filter captures airborne particles from outside before they enter the passenger compartment, improving the air you breathe and reducing dust on interior surfaces. It also protects the HVAC components from contaminant buildup that can reduce airflow and comfort.

• Replaces OEM cabin numbers WP10447 / 27277-6CA0A and equivalents for correct fit.
• Traps pollen, dust, and road particles to improve cabin air quality.
• Helps maintain heater and air-conditioner efficiency by keeping vents cleaner.

Is installation difficult and how often should I replace them?

Both filters are designed as serviceable, bolt-in replacements compatible with Nissan factory housings; many owners can install them with basic hand tools in a short garage session. For typical driving, Kefly recommends swapping both filters roughly every 12 months or every 12,000 miles—more often in dusty or polluted environments.

• Typical replacement interval: about 12 months / 12,000 miles under normal conditions.
• Simple removal and re-fit into factory filter boxes—no modification required.
• Check more frequently in heavy dust, construction, or severe climates.

Which vehicles and part numbers does this kit replace?

This two-piece set is made to match fit and function for the 2.0L DOHC Sentra models from model years 2020 through 2025. It stands in for several OEM references so you can be confident it’s the correct selection when those numbers are called out.

• Engine filter replaces OEM 16546-6LA0A and PA99575.
• Cabin filter replaces WP10447, 27277-6CA0A, 27277-6CA1A, and 27277-5NA1A.
• Specifically compatible with 2020–2025 Nissan Sentra L4 2.0L DOHC petrol models.

Who is this for? This Kefly air filter kit is suited to Sentra owners, DIY maintenance enthusiasts, and independent shops that want a reliable, easy-to-install replacement set matching factory dimensions and OEM part numbers. If you prioritize maintaining intake cleanliness and improving in-cabin air conditions on a regular maintenance schedule, this pair provides a cost-effective, direct-fit solution.
