RVgolf Engine & Cabin Air Filter Kit for Nissan Altima 2.5L (2019–2026) — High-Efficiency Direct-Fit

RVgolf Engine+Cabin Air Filter kit provides high-efficiency filtration and low-resistance airflow specifically designed for the 2019–2026 Nissan Altima 2.5L to protect the engine and improve in-cabin air quality.

This matched pair includes an engine air filter and a cabin air filter tailored for the 2.5L Altima model years 2019 through 2026. Both parts use advanced media and construction to trap particulates while minimizing airflow restriction, making replacement quick and straightforward for DIY owners or service technicians. The set replaces factory numbers CA12551 and 165466CA0A for the engine, and 272776CA1A / 272775NA1A for the cabin—confirm fitment with your vehicle before ordering.

How do these filters improve my Nissan Altima's performance?

Cleaner intake air helps the engine operate more efficiently by reducing dirt and debris entering the combustion system. The low-resistance design preserves airflow, which can support steady throttle response and reduce unnecessary strain on intake components.

• High-fiber engine media captures fine particles while maintaining airflow.
• Low-pressure-drop construction reduces intake restriction and noise.
• Direct-fit dimensions align with factory housings—no trimming required.

What does the cabin filter do for the interior environment?

The cabin filter uses multiple filtration layers to trap dust, pollen, and many common airborne particles while also reducing some odors and contaminants. It’s designed for quiet airflow so HVAC noise remains low when the fan runs at different speeds.

• Multi-layer media captures suspended impurities and common allergens.
• Low-resistance layout minimizes blower noise and maintains vent flow.
• Helps keep the passenger compartment fresher between maintenance intervals.

Which model years and part numbers does this kit replace?

This RVgolf kit is built for the Nissan Altima 2.5L from 2019 up through 2026. It matches OEM sizing and replaces the commonly referenced numbers to simplify cross-referencing during purchase and installation.

• Engine filter replacements: CA12551 and 165466CA0A.
• Cabin filter replacements: 272776CA1A and 272775NA1A.
• Always verify the part numbers against your vehicle’s existing filters before ordering.

How easy is it to swap these filters and how often should I change them?

Both filters are engineered for straightforward, no-fuss installation that most owners can do with basic tools. RVgolf recommends routine replacement to maintain protection and airflow, with service intervals based on driving conditions.

• Typical change interval: about every 12 months or 12,000 miles under normal driving.
• Shorter intervals advised for dusty, polluted, or heavy-stop urban driving.
• Design fits into factory housings for a quick, tool-light swap by drivers or technicians.

Who is this for: This RVgolf Engine+Cabin Air Filter kit is ideal for Nissan Altima 2.5L owners (2019–2026) who want a direct-fit replacement that balances high filtration efficiency with low airflow resistance.
