KAX Engine & Cabin Air Filter Kit for Hyundai & Kia — CF12820 + CA12816, OE Fitment & Activated Charcoal

This two‑piece replacement set includes one engine air filter (CF12820) and one cabin air filter (CA12816), engineered to match OE fitment for many 2020–2026 Hyundai and 2021–2026 Kia vehicles. Built with multi‑layer filter media and coconut shell‑based activated charcoal in the cabin element, the kit aims to reduce particulates, controls odors, and maintain proper airflow to protect engine performance and passenger comfort. The package is sold as a single purchase so you can service both filters at once without ordering parts separately.

Which cars will this KAX kit fit?

The KAX CF12820 CA12816 kit fits a range of Hyundai and Kia models when replacing OE numbers 97133‑L0000 (cabin) and 28113‑L1000 (engine). It’s specified for various model years and trims that originally used those part numbers.

• Compatible models include 2022–2025 Hyundai Tucson and 2021–2025 Hyundai Santa Fe.
• Also fits 2020–2026 Hyundai Sonata and 2022–2026 Hyundai Santa Cruz.

How does this pair protect engine performance and cabin comfort?

The engine filter controls dust and debris entering the intake to help sustain fuel efficiency and throttle response, while the cabin filter captures pollen, dust, and urban particulates and uses activated charcoal to address odors. Together, they reduce contaminant load both under the hood and inside the passenger compartment.

• Engine filter: multi‑layer media traps fine dust to protect mass airflow sensors and combustion components.
• Cabin filter: activated charcoal layer neutralizes common odors and traps allergens.
• Matched kit ensures both systems are refreshed simultaneously for balanced maintenance.

How easy is installation and when should I replace these filters?

Both filters are designed for straightforward, tool‑light installation—most owners can complete the swap in about five minutes per filter. KAX recommends replacing them together every 12 months or 12,000 miles to maintain airflow, filtration efficiency, and odor control.

• Quick swap: simple access locations and OE‑style fit make installation fast.
• Maintenance interval: suggested annual or 12,000‑mile replacement cadence for consistent performance.
• Buying the combo eliminates forgotten replacements and reduces return service trips.

What materials and features are included in the KAX kit?

The filters combine durable pleated media with a specialty activated charcoal layer in the cabin element. The kit is manufactured to meet form, fit, and function expectations for the referenced OE part numbers, focusing on particle capture and odor adsorption.

• Cabin filter: coconut shell activated charcoal plus multi‑layer filtration media.
• Engine filter: reinforced pleated media for high dust‑holding capacity and airflow balance.
• Packaged as a two‑filter maintenance bundle for convenience and cost savings.

Who is this for: The KAX CF12820 CA12816 kit is aimed at Hyundai and Kia owners who prefer to perform scheduled maintenance themselves or want a cost‑effective, convenient way to renew both cabin and engine filtration at the same time. It’s suitable for drivers seeking OE‑style fitment, improved in‑car air freshness, and reliable engine protection without the need to source parts separately.
