Kefly Mazda Filter Kit — Engine Air, Oil & Cabin Filters for 2014–2025 Non-Turbo Models (3/6/CX-5)

Kefly’s Filter Kit combines a CA11259 engine air filter, PE01-14-302A oil filter, and KD45-61-J6X cabin air filter to provide engine protection, cleaner cabin air, and reliable oil filtration for compatible Mazda models.

This three-piece replacement kit is built for naturally aspirated Mazda 3, Mazda 6 (non-turbo), and CX-5 models listed in the compatibility section. Each element—the engine air filter, oil filter, and cabin air filter—is manufactured with purpose-driven materials: breathable media for intake, electrostatic multi-layer media for the cabin, and reinforced metal components for the oil filter. The set is intended to restore filtration performance after wear and to meet recommended service intervals for typical driving conditions.

Which Mazda models and engines does this kit fit?

The Kefly kit fits specific years and engine displacements of Mazda 3, Mazda 6, and CX-5. It is designed for naturally aspirated (non-turbocharged) engines where noted, and covers both SkyActiv 2.0L and 2.5L variants where applicable.

• Mazda 3 (2014–2018) — 2.0L SkyActiv and 2.5L engines, including Sports models.
• Mazda 6 (2014–2021) — compatible with naturally aspirated engines only (non-turbo).
• Mazda CX-5 (2013–2025) — 2.0L and 2.5L naturally aspirated options (non-turbo versions).

How do each of these filters help my car run cleaner and longer?

Each filter performs a distinct role to protect engine performance and interior air quality. The engine air filter keeps dirt and particles out of the intake; the oil filter removes contaminants from engine oil; and the cabin filter reduces dust and odors entering the passenger compartment.

• Engine air filter: high-breathability fabric resists deformation and traps particulates before they reach the engine.
• Oil filter: metal end caps and reinforced center tube improve durability and filtration under pressure.
• Cabin filter: multi-layer electrostatic media captures pollen, dust, and odor-carrying particles.

What are the replacement numbers and compatibility references?

If you compare part numbers or are matching to a dealer reference, the kit’s pieces cross to many OEM and aftermarket codes. This makes it straightforward to confirm fitment against existing parts on your vehicle.

• Engine air filter cross-references: CA11259, A26280, AF-5211, 49247, PE07-13-3A0A and related codes.
• Cabin air filter cross-references: CPJ6X, CF11811, KD45-61-J6X, KR11-61-J6X and similar.
• Oil filter cross-references: PE01-14-302, PE01-14-302A and related PE01 codes.

When should I replace each filter in the kit?

Kefly provides a recommended maintenance cadence to keep filtration performing as intended. Actual intervals depend on driving conditions, climate, and load, but these baseline intervals suit normal driving patterns.

• Oil filter: replace approximately every 6 months or 5,000 kilometers (whichever comes first).
• Engine air filter: replace approximately every 12 months or 10,000 kilometers.
• Cabin air filter: replace approximately every 12 months or 10,000 kilometers.

Who is this kit for? This Kefly Filter Kit is aimed at Mazda owners who want a coordinated set of replacement filters matching common OEM and aftermarket numbers for the specified model years. It’s a practical choice for DIY maintenance, independent shops, and drivers who want to restore intake airflow, protect engine oil circulation, and improve interior air quality without mixing parts from different suppliers. If your Mazda falls within the listed years and uses naturally aspirated engines where indicated, this kit gives a convenient, single-order solution to refresh core filtration components.
