KAX CA12057 CF12058 Engine & Cabin Air Filter for Hyundai

KAX CA12057 CF12058 is a two-piece replacement kit that includes one engine air filter and one cabin air filter designed to restore engine breathing and improve in-cabin air for select Hyundai and Kia models.

This KAX dual-filter kit is built as a straightforward maintenance solution: an engine air filter tuned to protect the intake system and a cabin air filter that combines multi-layer media with coconut shell-activated charcoal to reduce odors. It’s intended for Hyundai Elantra (2017–2020), Elantra GT (2018–2020) and Kia Forte (2019–2024). The bundle simplifies servicing by putting both filters in a single purchase so drivers can replace them together on the recommended schedule.

Will these filters fit my Hyundai Elantra or Kia Forte?

Yes—this kit is matched to specific model years where factory dimensions and mounting points are compatible. Always cross-check part numbers and your vehicle’s year to confirm fit before ordering.

• Compatible models: Hyundai Elantra 2017–2020, Elantra GT 2018–2020, Kia Forte 2019–2024
• Contains: 1 engine air filter (CA12057 equivalent) and 1 cabin air filter (CF12058 equivalent)
• Check your owner’s manual or existing filter part numbers for verification

How do these filters improve driving comfort and engine health?

The engine filter traps dust and debris before they reach sensitive intake components, helping maintain airflow and combustion efficiency. The cabin filter captures pollen, dust and pollutants while the activated charcoal layer reduces common odors for a fresher passenger compartment.

• Engine filter: multi-layer media catches particulates to protect the engine
• Cabin filter: particulate filtration plus coconut shell-activated charcoal for odor control
• Dual replacement reduces the chance of overlooking either filter during service

How difficult is installation and what tools will I need?

Installation is designed for quick, owner-friendly replacement and usually takes about five minutes for each filter with basic tools. The engine and cabin filter locations are accessible without advanced mechanical skills, but working safely and following your vehicle’s service guide is recommended.

• Estimated time: ~5 minutes per filter for typical installations
• Tools: common hand tools (screwdriver or socket set) may be required depending on access panels
• Tip: Replace both at the same time to simplify future maintenance

When should I replace these filters and what maintenance benefits can I expect?

KAX recommends replacing the engine and cabin filters together every 12 months or every 12,000 miles, whichever comes first. Timely replacement preserves engine breathing, helps maintain HVAC performance, and keeps cabin air more pleasant and allergen-reduced.

• Replacement interval: every 12 months or 12,000 miles
• Benefits: consistent engine airflow, reduced HVAC strain, and improved cabin air quality
• Buying the combo saves time and ensures coordinated maintenance

Who is this for: Drivers who own the listed Hyundai or Kia models and want a convenient, single-purchase maintenance solution that covers both engine filtration and cabin air freshness. It’s suitable for DIY owners who prefer quick, tool-light replacements, fleet managers who standardize preventative care, and anyone seeking to reduce odors and particulates inside the vehicle while protecting engine components from debris.
