StaunchAuto Engine & Cabin Air Filter Combo for Infiniti QX50/QX55 2019-2025 — Activated-Carbon Cabin, Durable ABS Engine Filter

StaunchAuto’s Engine & Cabin Air Filter Combo replaces the engine air filter (165465NA1C) and cabin filter (272775NA1A) for Infiniti QX50 2.0L (2019–2025) and QX55 (2022–2025), combining high-capacity engine filtration with activated-carbon cabin purification.

This paired filter set is engineered to fit Infiniti QX50 and QX55 model years specified above, delivering targeted protection for the engine intake and cleaner air inside the vehicle. The engine element uses durable filter media and an ABS frame for extended life, while the cabin element employs coconut-shell activated carbon and a dual-layer structure to capture particles and absorb odors. The combo is intended to be a straightforward, cost-conscious replacement you can install as part of routine maintenance every six months or up to 12,000 miles.

How does the engine filter protect my Infiniti’s 2.0L motor?

The engine filter traps airborne dust, road debris, and other contaminants before they reach the intake system, helping maintain efficient combustion and reduce wear. Its reinforced ABS frame keeps the filter media stable under varying airflow and temperature conditions, extending service life compared with ordinary filters.

• High-quality filter paper captures fine particulates
• ABS frame prevents deformation under pressure
• Designed to match 165465NA1C fit and airflow requirements

What benefit does the cabin filter offer for passengers?

The cabin filter uses a double-layer design with coconut-shell activated carbon to reduce unpleasant smells and adsorb certain airborne gases, while the dual media screens out pollen, dust and other particles. It also prioritizes low airflow resistance so HVAC performance and interior comfort remain consistent.

• Coconut-shell activated carbon for odor adsorption
• Double-layer filtration captures 99.9% of particulates
• Low resistance design keeps ventilation quiet and steady

How often should I replace these filters and why?

Replace both filters approximately every six months or up to 12,000 miles, whichever comes first, to keep filtration efficiency high and prevent clogging. Regular replacement reduces the chance of reduced engine airflow, degraded HVAC performance, and lingering interior odors—and it can be an economical way to avoid more extensive maintenance down the road.

• Recommended interval: 6 months or 12,000 miles
• Timely changes maintain engine efficiency and cabin air quality
• Cost-effective preventive maintenance compared to major repairs

Will this combo fit my Infiniti QX50 or QX55 model year?

Yes—this filter set is specifically produced to fit Infiniti QX50 2.0L models from 2019 through 2025 and Infiniti QX55 models from 2022 through 2025. The engine replacement corresponds to part 165465NA1C and the cabin replacement corresponds to part 272775NA1A, offering direct compatibility with those factory item numbers.

• Engine filter replaces OEM 165465NA1C
• Cabin filter replaces OEM 272775NA1A
• Fits QX50 2.0L (2019–2025) and QX55 (2022–2025)
