PHILTOP Engine & Cabin Air Filter Kit for Mazda CX-5 2013–2025, Fits Mazda 3/6 — Direct-Fit OE-Style Pair

PHILTOP’s two-piece air filter kit includes a direct-fit engine air filter and cabin air filter tailored for Mazda CX-5 (2013–2025) and compatible Mazda 3 and 6 models.

This matched engine and cabin filter set is made to replace Mazda part numbers CA11259 (engine) and CF11811 (cabin) so you can refresh both airflow systems in one purchase. The kit is engineered for straightforward OE-style installation and is intended to restore filtration efficiency for particles, dust and common pollutants that affect engine performance and in-cabin air quality. Buying the pair together simplifies maintenance and helps keep service intervals consistent.

How will replacing both filters together help my Mazda?

Replacing the engine and cabin filters at the same time ensures both the drivetrain intake and the passenger compartment benefit from fresh filtration. That coordinated approach supports steady engine airflow while also improving the quality of air you and your passengers breathe.

• Engine filter traps road dust and debris to protect the intake and sensors.
• Cabin filter reduces pollen, dust and common odors entering the cabin.
• Paired replacement helps maintain consistent airflow performance for both systems.

Will these filters fit my exact vehicle model and year?

The PHILTOP kit is formulated to fit Mazda CX-5 models from 2013 through 2025 with the specified engine, and select Mazda 3 (2014–2018) and Mazda 6 (2014–2021) 2.5L applications. Use your vehicle’s make, model and year to confirm compatibility before ordering to guarantee a direct OE-style fit.

• Engine filter mapped to replacement part CA11259.
• Cabin filter replaces part CF11811.
• Compatible with Mazda CX-5 2013–2025 and listed Mazda 3/6 years.

How simple is installation for a DIYer?

Both filters are designed for intuitive, tool-light replacement. The cabin filter typically swaps out behind the glovebox in minutes, while the engine filter lifts into place under the hood with an OE-style fit and clear orientation markings.

• Cabin filter accessible behind the glovebox; usually no tools required.
• Engine filter installs directly into the factory airbox with common fasteners.
• Included guidance speeds up the process for first-time installers.

When should I change these filters again?

PHILTOP recommends replacing both the cabin and engine filters every 12 months or every 12,000 miles, whichever comes first. That interval helps sustain airflow, filtration efficiency and consistent system performance in typical driving conditions.

• Suggested schedule: 12 months / 12,000 miles.
• Shorten intervals sooner in dusty or polluted environments.
• Replacing both filters together keeps maintenance simple and predictable.

Who is this for: drivers who want a ready-made, compatible filter kit for routine service — especially Mazda CX-5 owners (2013–2025) and those with compatible Mazda 3 or 6 models — who prefer a one-box solution to refresh both engine intake and cabin air filtration. The PHILTOP kit suits DIY enthusiasts and professional technicians who need accurate fitment, clear installation and coordinated maintenance intervals without shopping for separate parts.
