Kefly Engine & Cabin Air Filter Kit for 2010–2021 Toyota/Lexus Hybrids — High Breathability Engine Filter, Electrostatic Cabin Fil

The Kefly CA10741 engine air filter paired with the CF10285 cabin air filter is a two-piece replacement kit designed to protect your hybrid's engine performance and cabin air quality.

This matched filter set is built for a range of Toyota and Lexus hybrid models and combines a high-breathability engine element with a multi-layer electrostatic cabin filter. The engine filter supports consistent airflow while resisting deformation, and the cabin filter reduces odors and traps fine particles to help keep the interior air fresher between service intervals. The kit replaces several OEM part numbers, making it a convenient option for routine maintenance on popular hybrid platforms.

Which vehicles will these filters fit?

These two filters are made to fit several Toyota and Lexus hybrids with 1.8L and 2.5L engines. Confirm fit by matching your vehicle year and engine size before purchasing.

• 2010–2015 Toyota Prius L4 1.8L
• 2012–2015 Toyota Prius Plug-In L4 1.8L
• 2012–2018 Toyota Prius V L4 1.8L
• 2016–2018 Toyota RAV4 L4 2.5L Hybrid
• 2011–2017 Lexus CT200h L4 1.8L
• 2015–2021 Lexus NX300h L4 2.5L

How do these filters compare to original equipment (OEM)?

The Kefly engine element and cabin filter are engineered to meet or closely match OEM dimensions and filtration characteristics while using durable media and electrostatic layers. They replace the listed OEM numbers for straightforward swapping during scheduled maintenance.

• Engine filter cross-references: CA10741, CF10285, CP285, 17801-37020, 17801-37021, FDPAF741.
• Cabin filter cross-references include many 87139-series Toyota/Lexus part numbers.
• Constructed with breathable, tear-resistant media and multi-layer electrostatic material for particle capture.

When should I replace the engine and cabin filters?

Replace intervals depend on driving conditions, but a reasonable baseline is once per year or roughly every 10,000 kilometers. Replace sooner if you frequently drive in dusty environments, heavy traffic, or areas with pollen and smoke.

• General recommendation: change both filters every 12 months or 10,000 km.
• Inspect earlier when driving in severe conditions—dust, construction, or high pollen seasons.
• Signs to replace: reduced HVAC airflow, persistent odors, or decreased engine responsiveness.

What benefits will I notice after installing this filter kit?

Installing the Kefly filters restores designed airflow to the engine and helps maintain a cleaner cabin environment. You should expect steadier engine breathing and reduced in-cabin dust and odors compared with worn filters.

• Sustained engine airflow for consistent performance and efficiency.
• Multi-layer cabin media captures fine particulates and reduces odors.
• Durable materials resist tearing and deformation during installation and use.

Who is this for: drivers of compatible Toyota and Lexus hybrid models who perform their own maintenance or prefer aftermarket replacement parts that match OEM fit and function. This kit suits owners seeking a cost-effective, matched engine-and-cabin filter solution that restores airflow, helps protect engine components, and improves interior air quality between scheduled services.
