KAX CA11426 CF12157 Engine & Cabin Air Filter kit for

This KAX filter kit combines an engine air filter (CA11426) and a cabin air filter (CF12157) in one purchase for Toyota Prius, Prius Prime, Prius AWD‑e, and select Corolla Hybrid years. Both elements use multi-layer filtration and coconut shell‑activated charcoal to trap particulates and neutralize common odors while being straightforward to install. The set is designed so owners can replace both filters at the same service interval to keep engine performance steady and cabin air fresher without separate orders or extra downtime.

Which Toyota models and years does this kit fit?

The KAX kit fits Toyota Prius models from 2016 through 2022 (from 11/2015 production) plus Prius Prime 2017–2022 and Prius AWD‑e 2019–2022. It also suits Corolla Hybrid 1.8L models from 2020–2026. Always verify with your vehicle’s owner manual or a VIN check before ordering to ensure exact fitment.

• Toyota Prius (2016–2022, from 11/2015)
• Toyota Prius Prime (2017–2022)
• Toyota Prius AWD‑e (2019–2022)
• Toyota Corolla Hybrid 1.8L (2020–2026)

How do these filters improve engine and cabin conditions?

The engine air filter removes dust, pollen, and road debris before air reaches the intake, helping maintain combustion efficiency and protecting internal components. The cabin filter captures particulates and, thanks to coconut shell‑activated charcoal, reduces odors and gas vapors entering the passenger compartment. Together they support cleaner airflow for both engine performance and occupant comfort.

• Multi-layer media traps fine and coarse particulates
• Activated charcoal neutralizes common odors and VOCs
• Engine protection reduces contaminant-related wear
• Cabin comfort increases by lowering dust and smells

Is installation difficult and how long does it take?

Installation is designed to be user-friendly and typically takes about five minutes for each filter when you have basic hand tools. The engine filter is accessed from the engine bay while the cabin filter is behind the glove box or under the dash depending on the model year. Clear replacement orientation and OEM‑compatible dimensions make the swap straightforward for DIYers and technicians alike.

• Estimated install time: ~5 minutes per filter
• Standard tools: screwdriver or small socket set
• Includes both filters—no extra orders needed
• Follow vehicle manual for exact removal steps

When should I replace these filters and what are the benefits?

KAX recommends replacing the engine and cabin filters together every 12 months or every 12,000 miles to maintain air quality and engine efficiency. Replacing both at the same interval prevents one filter from becoming a new source of restriction or odor and simplifies routine maintenance planning. Regular replacement supports consistent airflow, reduces in‑car dust and smells, and helps preserve downstream HVAC and engine components.

• Recommended interval: 12 months / 12,000 miles
• Cost-efficient to replace both simultaneously
• Prevents reduced airflow and odor buildup
• Helps protect HVAC system and engine intake

Who is this for: The KAX CA11426 CA11426 / CF12157 kit is aimed at Toyota hybrid owners who prefer a single, convenient maintenance purchase that addresses both engine intake protection and in‑car air quality. It's suited to DIYers who want an OEM‑style fit without separate orders, service shops that perform routine filter swaps, and drivers seeking better cabin comfort and straightforward filter maintenance planning.
