KAX Engine & Cabin Air Filter Kit for Ford, Lincoln, Mazda — CA10242/CF10547, High‑Efficiency + Charcoal

KAX CA10242 CF10547 is a two-piece replacement kit containing one engine air filter and one cabin air filter designed to restore engine breathing and improve in-cabin air quality for compatible Ford, Lincoln, and Mazda SUVs.

This matched filter set is built as a convenient, single-purchase maintenance solution for Ford Edge (2007–2014), Lincoln MKX (2007–2015), and Mazda CX-9 (2007–2015). The kit pairs a high-efficiency engine air filter with a charcoal-activated cabin filter so both powertrain protection and occupant comfort are addressed at the same service interval. The filters are made with multi-layer media for particle capture and an activated-coconut-shell charcoal layer to reduce odors inside the vehicle.

How does this kit improve engine performance?

The engine air filter in this KAX kit traps dust, pollen, and road debris before they reach the intake system, helping preserve airflow and reduce wear on engine components. Cleaner air for combustion supports steady fuel delivery and responsive acceleration under normal driving conditions.

• High-flow filter media maintains proper intake airflow.
• Multi-layer construction captures both large and fine particles.
• Direct-fit design ensures proper sealing and easy installation.

What benefits does the cabin filter provide for passengers?

The cabin filter uses coconut shell-activated charcoal and pleated filtration to capture airborne particulates and help reduce odors and exhaust smells from entering the passenger compartment. This produces a fresher cabin environment, especially in urban or high-traffic driving.

• Charcoal layer neutralizes common vehicle odors.
• Pleated media removes dust, pollen, and debris.
• Installation reduces dust circulation and HVAC buildup.

How easy is it to replace both filters?

KAX engineered this kit as a quick-maintenance bundle: each filter is a direct replacement for factory parts and can typically be swapped in around five minutes when following the vehicle’s service steps. Combining both filters into one purchase removes guesswork and prevents staggered replacements.

• Direct-fit parts match OEM mounting points.
• Basic hand tools (if any) are sufficient for installation.
• Single-kit purchase saves time and reduces future service steps.

When should these filters be replaced together?

KAX recommends replacing the engine and cabin filters as a pair approximately every 12 months or every 12,000 miles, whichever comes first, to maintain consistent air quality and engine protection. Replacing them together keeps both the intake system and cabin ventilation performing optimally without staggered maintenance intervals.

• 12 months / 12,000 miles suggested replacement interval.
• More frequent replacement in dusty or high-pollution environments.
• Buying the combo simplifies long-term maintenance planning.

Who is this for: The KAX CA10242 CF10547 kit is for owners of Ford Edge (2007–2014), Lincoln MKX (2007–2015), and Mazda CX-9 (2007–2015) who want a straightforward way to refresh both engine intake protection and cabin air quality in one purchase. It suits DIY enthusiasts, independent mechanics, and fleet managers who prefer a matched, time-saving replacement that uses activated charcoal for odor control and multi-layer media for reliable particle filtration.
