Kefly Filter Kit for Mazda 3/6/CX-5 (2013–2025) — 3-Piece Engine, Oil & Cabin Filters, High-Flow + Electrostatic

The Kefly Filter Kit combines a high-flow engine air filter, a reinforced oil filter, and a multi-layer cabin air filter to protect engine performance and improve in-car air quality for compatible Mazda models.

This three-piece replacement set is engineered to match factory fit and service intervals for many Mazda 3, Mazda 6 (naturally aspirated), and CX-5 models. Each component uses upgraded materials — breathable media for the engine intake, electrostatic multilayer media for the cabin, and metal-reinforced construction for the oil filter — so the drivetrain breathes cleaner and the cabin smells fresher between services.

Which Mazda models will this Kefly kit fit?

The kit fits multiple Mazda variants across model years when equipped with naturally aspirated engines listed below. Check your vehicle’s year, engine size and whether the motor is turbocharged before ordering.

• Mazda 3 (2014–2018): 2.0L SkyActiv and 2.5L versions, including Sport models.
• Mazda 6 (2014–2021): compatible with naturally aspirated (non-turbo) engines only.
• Mazda CX-5 (2013–2025): compatible with 2.0L (2013–2019) and 2.5L naturally aspirated engines (2013–2025).

How do the three filters improve performance and comfort?

Each filter targets a different source of wear and contamination: the engine air filter reduces debris reaching the intake, the oil filter protects the lubrication system, and the cabin filter traps dust and odors. Combined, they help maintain steady airflow, cleaner oil circulation, and fresher interior air between scheduled services.

• Engine air: high-breathability fabric resists deformation and tearing for consistent airflow.
• Oil filter: metal end caps and center tube increase durability under pressure and heat.
• Cabin air: industrial electrostatic media and multiple layers capture particles and odors.

What replacement numbers and equivalents does this kit cover?

The Kefly kit is cross-referenced to many OEM and aftermarket part numbers so you can confirm fitment against your vehicle’s current filters. This simplifies sourcing and helps ensure compatibility during maintenance.

• Engine air filter equivalents include CA11259, A26280, AF-5211, 49247 and related codes.
• Cabin air equivalents include KD45-61-J6X, CF11811, CPJ6X and others.
• Oil filter equivalents include PE01-14-302A and related PE01-14-302 variants.

How often should I change each filter in the Kefly kit?

Follow recommended service intervals for reliable protection: oil filters require more frequent replacement than air filters, while the cabin filter depends on driving environment and particle exposure.

• Oil filter: replace approximately every 6 months or 5,000 kilometers (whichever comes first).
• Engine air filter: replace about every 12 months or 10,000 kilometers.
• Cabin air filter: same 12-month / 10,000 km guideline; adjust sooner for dusty or polluted areas.

Who is this kit for? The Kefly Filter Kit is suited for Mazda owners who perform routine DIY maintenance or independent shops that service naturally aspirated Mazda 3, Mazda 6 (non-turbo), and CX-5 models and want reliable, cost-effective replacements. It’s ideal for drivers seeking direct-fit aftermarket parts with reinforced construction and improved particle-trapping cabin media, plus clear cross-reference numbers to match existing components. If you’re unsure about engine type or turbo status, confirm your VIN or consult a dealer before purchase to ensure correct fitment.
