Dacall Cabin & Engine Air Filter Combo for Mazda 3/6/CX-5 (NA) — HEPA Cabin + Pleated Engine

Dacall's Cabin & Engine Air Filter Replacement Combo supplies two precision-fit filters engineered to restore airflow, block fine dust and odors, and match OE fitment for naturally aspirated Mazda 3, Mazda 6, and CX-5 models.

This two-piece replacement kit includes a cabin air filter and an engine intake filter sized for specific naturally aspirated Mazda engines (not compatible with turbocharged variants). Each filter is manufactured to align with original-equipment dimensions and mounting points so you can swap them in without modification. The cabin element uses a multilayer design including activated coconut carbon and a HEPA-style layer, while the engine filter uses a pleated media to protect the intake system and maintain fuel economy.

Which Mazda models and engines does this combo fit?

This Dacall set is intended for naturally aspirated gasoline Mazda vehicles only — not turbocharged engines. Compatible fitment covers Mazda 3, Mazda 6, and CX-5 across specific years and displacements listed below.

• Mazda 3 (2014–2018) 2.0L / 2.5L naturally aspirated
• Mazda 3 Sport (2014–2018) 2.0L / 2.5L naturally aspirated
• Mazda 6 (2014–2021) 2.5L naturally aspirated
• Mazda CX-5 (2013–2019) 2.0L naturally aspirated; (2014–2025) 2.5L naturally aspirated
• Not compatible with turbocharged variants — check engine type before ordering

How does the cabin filter improve in-car air quality?

The cabin filter employs a four-layer filtration system engineered to reduce odors and trap fine particles commonly found on roads. It combines activated coconut carbon for gas adsorption with a HEPA-style layer that captures submicron particulates, helping to keep the HVAC system cleaner and reducing airborne allergens inside the cabin.

• Coconut carbon layer reduces exhaust and roadside fumes
• HEPA-style layer captures particles down to 0.3 microns (lab-tested)
• Microfiber mesh blocks larger dust and grit
• Reinforced frame resists collapse in humid conditions

What performance or maintenance benefits can I expect?

Replacing both the cabin and engine filters at recommended intervals restores restricted airflow and helps the engine breathe freely, which can stabilize idle and protect downstream components. Dacall notes faster airflow versus clogged elements and provides guidance on when to replace filters to avoid HVAC or engine performance issues.

• Improved airflow: up to 17% faster than clogged filters
• Helps prevent MPG loss linked to a dirty engine filter
• Swap interval guidance: roughly every 12 months or 12,000 miles
• Easy DIY install — typically 5–8 minutes per filter

Are these filters direct replacements for OE part numbers?

Yes — the combo is produced to match common OE references so it can replace many original part numbers for both cabin and engine filters. A quick compatibility check using the vehicle part-finder is recommended before ordering to confirm exact fitment for your model and year.

• Cabin filter cross-references common OE codes used across Mazda models
• Engine filter lists multiple OE equivalents for straightforward replacement
• Designed for precision fit — edges and frames align with OEM slots
• Contact support for fit questions or installation help

Who is this for: Drivers who own naturally aspirated Mazda 3, Mazda 6, or CX-5 models and want an economical, convenience-focused solution to refresh both cabin air quality and engine intake protection. This combo suits DIYers and maintenance-conscious owners who prefer replacing both filters together to ensure consistent performance and reduce return trips to parts suppliers. Verify engine type and model year before purchase — this kit does not fit turbocharged engines.
