ryvclim Engine & HEPA Cabin Air Filter Combo for Nissan Altima 2.5L 2019-2026 — CF12552 & CA12551, Direct-Fit Replacement

If you drive a Nissan Altima with the 2.5L engine, keeping both the engine intake and cabin ventilation filters fresh improves airflow and reduces dust, pollen and airborne particles that enter the engine bay and passenger compartment. ryvclim's kit pairs a performance-minded engine filter with a high-efficiency HEPA-style cabin filter plus a removal tool, so you can swap both filters at once during routine maintenance.

How will the engine air filter affect my Altima's intake airflow?

The ryvclim engine filter is built to trap dirt and road debris while preserving unrestricted airflow to the engine. Cleaner air entering the combustion system helps the intake stay free of contaminants that can reduce efficiency over time.

• Pleated media captures dust and larger particulates before they reach the throttle body.
• Designed to maintain steady airflow characteristics for the factory 2.5L intake.
• Durable frame resists deformation during installation and service intervals.
• Direct-fit sizing for fast replacement and proper sealing in the airbox.

What benefits does the HEPA cabin filter provide for passengers?

The included HEPA-style cabin filter reduces fine airborne particles, helping the vehicle interior feel cleaner and mitigating odors and allergens that otherwise circulate through the HVAC system. It’s especially useful for city driving or high-pollen seasons.

• High-efficiency filtration captures dust, pollen and many fine particles.
• Improved air quality supports a fresher-smelling cabin and clearer vents.
• Form-fit design for the Altima cabin filter slot to prevent bypass.
• OEM-style thickness for reliable sealing with factory housings.

Is installation difficult and what tools are included?

Installation is straightforward for anyone comfortable with basic vehicle maintenance. ryvclim includes a removal tool to make extracting the old filter easier in tight spaces, and the filters are engineered for direct, no-modification fitment.

• Included filter removal tool helps loosen tightly seated cabin filters.
• Step-by-step replacement typically requires simple hand tools and minimal disassembly.
• Both filters match factory dimensions to eliminate trimming or adapters.
• Packaging includes instructions and part numbers (CF12552 & CA12551) for reference.

How often should I replace both filters in my Altima?

Replacement intervals vary by driving conditions, but a good baseline is inspecting the engine and cabin filters every 12 months or 12,000–15,000 miles. If you frequently drive on dusty roads, in heavy traffic, or in high-pollen areas, check and replace them sooner.

• Normal conditions: inspect every 12 months or 12,000–15,000 miles.
• Dusty or off-road use: inspect more frequently, replace as needed.
• City driving with poor air quality: consider cabin filter swaps every 6–12 months.
• Always follow manufacturer service guidelines for engine maintenance.

Who is this kit for? ryvclim’s CF12552 & CA12551 combo is aimed at Nissan Altima owners with the 2.5L engine who want a straightforward, value-packed filter replacement that addresses both engine protection and cabin air quality. It’s a convenient option for DIYers performing routine service and for technicians seeking a single-purchase solution to replace both filters during scheduled maintenance. Note: this kit is not compatible with the Altima 2.0L turbo engine—verify engine size before ordering.
