KAX Engine & Cabin Air Filter Kit for Mazda 3 2012-2013 2.0L — CA11259 & CF11672, charcoal cabin + multilayer engine media

KAX CA11259 CF11672 is a two-piece replacement kit containing an engine air filter and a charcoal cabin air filter engineered for Mazda 3 2012–2013 2.0L models.

This combined kit replaces both the engine and cabin filters in one purchase, simplifying routine maintenance for Mazda 3 owners. Each filter is built with multilayer media — the engine filter focuses on protecting engine components from dust and debris, while the cabin filter uses coconut shell-activated charcoal to reduce odors and capture fine particulates. Designed for quick installation, the set helps maintain airflow and comfort without needing separate orders or part searches.

How will the KAX filter kit affect my Mazda 3’s performance?

Replacing the engine filter with the KAX CA11259 helps preserve engine breathing efficiency by keeping dirt and abrasive particles out of intake systems. Cleaner intake air supports consistent fuel-air mixing and may help components operate as intended between services.

• High-efficiency media traps dust, pollen, and road grit before they reach the engine.
• Rigid frame maintains seal and fit in the factory airbox.
• OEM-compatible dimensions for an accurate, tool-minimal swap.

What makes the cabin filter different from standard filters?

The KAX CF11672 cabin filter uses activated charcoal derived from coconut shells to reduce odors and adsorb volatile compounds while mechanically filtering particulates. Its multi-layer construction captures airborne debris and improves in-car air quality compared with single-layer paper filters.

• Activated charcoal layer targets smells and light gases.
• Fine particulate layer traps pollen, dust, and soot.
• Designed to fit the Mazda 3 cabin filter housing for straightforward replacement.

How easy is installation and how often should I replace these filters?

Both filters are designed for quick, intuitive installation—most owners can complete the swap in about five minutes with basic tools or none at all. KAX recommends replacing both the engine and cabin filters together every 12 months or about every 12,000 miles so neither filter is neglected and overall system performance stays consistent.

• Set includes both engine and cabin filters to save time and avoid separate part orders.
• Simple vehicle-specific fit reduces installation guesswork.
• Replacement interval recommendation: 12 months / 12,000 miles for balanced maintenance.

Are these filters compatible with my vehicle and how do I confirm fit?
