KAX Engine & Cabin Air Filter Kit for Hyundai & Kia — CF12160/CA12065, Coconut-Charcoal Cabin, OEM-Fit

The KAX CF12160 CA12065 kit combines an engine air filter and a cabin air filter designed specifically to restore engine efficiency and improve interior air quality in compatible Hyundai and Kia models.

If you drive a Hyundai Tucson (selected 2016–2021 1.6T/2.0L years) or a Kia Sportage (2017–2022), this paired filter kit replaces both the engine and cabin filters in a single purchase. KAX engineered the kit with multi-layer filtration media and coconut shell–activated charcoal in the cabin filter to trap particulates and reduce odors while maintaining airflow for engine health. The two filters are matched to factory fit and are intended for straightforward DIY replacement in about five minutes, helping you stay on schedule with routine maintenance.

How will replacing both filters together improve my car’s day-to-day performance?

Changing the engine and cabin filters at the same time prevents one neglected filter from undermining the other. A clean engine filter helps maintain proper air intake and fuel efficiency, while a fresh cabin filter keeps the passenger area free from dust and odors.

• Engine filter maintains airflow for stable combustion and throttle response
• Cabin filter reduces dust, pollen and odors for a more comfortable cabin
• Simultaneous replacement saves time and lowers total maintenance visits
• OEM-fit design ensures correct sealing and easy installation

Why does the cabin filter use coconut shell–activated charcoal?

Coconut shell–based activated charcoal is a high-surface-area adsorbent that captures volatile molecules that cause smells and some gaseous impurities. When combined with fine particulate media, it gives two layers of protection: odor reduction plus particle capture.

• Natural charcoal adsorbs odors from traffic, smoke and HVAC smells
• Multi-layer media traps pollen, dust and finer particulates
• Helps maintain a fresher-feeling interior without chemical fragrances
• Compatible with cabin HVAC systems—no modification needed

How easy is it to install these filters myself?

The kit is made for quick, tool-minimal replacement and matches factory dimensions for direct fit. Typical installation for each filter takes only a few minutes, and no special skills are required beyond following simple vehicle-specific instructions.

• Engine filter fits the airbox with factory alignment tabs
• Cabin filter slides into the glovebox or under-hood housing depending on model
• Estimated combined install time: around 5 minutes for most owners
• Clearances and seals designed to reduce installation errors

When should I replace this KAX filter kit?

KAX recommends replacing both the engine and cabin filters together every 12 months or every 12,000 miles, whichever comes first. Frequency may vary with driving conditions—more frequent replacement is advised in dusty or urban environments.

• Standard replacement interval: 12 months / 12,000 miles
• Replace sooner if you notice decreased HVAC airflow or engine performance
• Check filters after long dusty trips or heavy urban pollution exposure
• Purchasing the combo kit makes synchronized maintenance straightforward

Who is this kit for? The KAX CF12160 CA12065 engine and cabin filter kit is aimed at owners of compatible Hyundai Tucson and Kia Sportage models who want a simple, cost-effective maintenance solution. It suits DIY drivers who prefer quick, reliable replacements using components designed to fit factory specifications, as well as fleet managers or caretakers looking to standardize routine service with a single ordered kit. If you want to reduce in‑cabin odors, improve air quality for passengers, and help keep engine intake running clean without multiple orders, this paired set provides a practical, time-saving option.
