StaunchAuto Engine & Cabin Air Filter Combo for Infiniti QX50 QX55 (2.0L, 2019–2025) — Reinforced ABS Engine Filter & Activated Ca

If your Infiniti is due for routine maintenance, this paired filter set offers two targeted upgrades in one purchase: a long-life engine air filter built with reinforced ABS framing and high-performance filter paper, and a cabin filter using coconut-shell activated carbon with dual-layer particle capture. Together they help keep engine airflow efficient while trapping dust, odors, and airborne particles before they reach passengers.

How will the engine filter affect performance and longevity?

The engine filter uses multi-layer media to trap contaminants that would otherwise enter the intake, protecting combustion components and preserving airflow. Its reinforced ABS frame resists deformation, so the filter keeps a proper seal throughout its service life, which the manufacturer rates at about twice that of basic paper filters.

• High-quality filter paper captures fine dust and debris.
• Rigid ABS frame maintains consistent sealing and fitment.
• Lower intake resistance supports fuel efficiency and throttle response.
• Recommended replacement every 6 months or 12,000 miles for best results.

What does the cabin filter remove from the interior air?

The cabin element combines a particle-trapping layer with coconut-shell activated carbon to reduce odors and adsorb gaseous pollutants. Its dual-layer construction targets pollen, dust, and many common vehicle odors, helping passengers breathe cleaner air while the HVAC system runs quietly.

• Activated carbon adsorbs odors and volatile compounds.
• Double-layer media screens out particles down to fine sizes.
• Engineered to reduce HVAC noise and maintain steady airflow.

Will these filters fit my Infiniti model and how easy is installation?

This combo is designed for Infiniti QX50 2.0L models from 2019 through 2025 and the QX55 for 2022–2025. The engine filter replaces part 165465NA1C and the cabin filter replaces 272775NA1A, matching OE dimensions for straightforward swap-in installation without modifications.

• Direct-fit replacements for the listed Infiniti part numbers.
• Simple installation using basic tools and OEM access points.
• Includes both engine and cabin elements—one purchase, two service items.

How does choosing this combo save money over time?

Regular filter changes help prevent buildup that can reduce engine efficiency or strain HVAC components; replacing both engine and cabin filters at recommended intervals is a low-cost preventative step. The longer-lasting engine media and odor-absorbing cabin carbon reduce the frequency of replacements and improve overall cabin comfort.

• Extended engine filter life reduces parts and labor frequency.
• Cabin carbon layer lowers need for additional odor treatments.
• Recommended service schedule: every 6 months or 12,000 miles.

Who is this for: drivers of Infiniti QX50 (2.0L) model years 2019–2025 and QX55 owners from 2022–2025 who want a cost-effective, OEM-compatible filter upgrade for improved intake protection and cleaner cabin air. It’s ideal for routine maintenance shoppers, do-it-yourselfers replacing both filters together, and anyone seeking quieter HVAC operation plus odor reduction without changing original equipment fitment.
