Kefly Air Filter Kit for Toyota Prius & RAV4 Hybrid (2010–2018) — Engine + Cabin Filters, High-Flow & Multi-Layer

This kit includes a high-flow engine air filter (CA10741) and a multi-layer cabin air filter (CF10285) designed to meet or exceed factory fit and filtration for a range of Prius, Prius Plug-In, Prius V, RAV4 Hybrid and selected Lexus hybrid models. Both filters use durable media and reinforced cores so they resist deformation and maintain performance over typical service intervals. The pair is sold together to simplify routine maintenance and keep intake and HVAC systems functioning efficiently.

Which cars will these Kefly filters fit?

The kit is tailored for several 1.8L and 2.5L hybrid applications from Toyota and Lexus. Fitment covers model years and trim variants where the listed OEM part numbers apply, so confirm compatibility with your vehicle's year and engine before ordering.

• 2010–2015 Toyota Prius L4 1.8L and 2012–2015 Prius Plug-In L4 1.8L
• 2012–2018 Toyota Prius V L4 1.8L

• 2011–2017 Lexus CT200h L4 1.8L and 2015–2021 Lexus NX300h L4 2.5L

How do these filters protect the engine and cabin air?

The engine air filter uses breathable, tear-resistant media and a reinforced core to capture particulates while preserving airflow to the intake. The cabin filter uses industrial electrostatic layers to trap dust, pollen and some odors before they enter the passenger compartment.

• Multi-layer electrostatic cabin media reduces allergens and visible dust
• High-breathability engine fabric balances filtration with airflow
• Reinforced cores resist deformation under installation and use

What OEM part numbers does this kit replace?

Kefly provides cross-reference coverage to make it simple to match these aftermarket filters to the original equipment numbers used by Toyota and Lexus. Use the listed replacement numbers to verify fitment against your vehicle’s existing filters or parts catalog.

• Engine filter cross-references: CA10741, CF10285, CP285, 17801-37020, 17801-37021, FDPAF741
• Cabin filter cross-references: CF10285 plus many 87139-series parts (see full list included with product)
• Keep OEM part numbers or your VIN handy when double-checking fit

How often should I replace these filters and what maintenance tips help them last?

Kefly recommends replacing both engine and cabin filters approximately every 12 months or every 10,000 kilometers, whichever comes first. Inspect filters more frequently in dusty or polluted environments and during heavy seasonal pollen to maintain airflow and cabin comfort.

• Replace annually or at ~10,000 km for typical driving conditions
• Inspect visually for heavy dirt, clogging, or damage before the interval
• Follow vehicle manufacturer service procedures when installing filters

It suits DIY vehicle owners, routine maintenance shops, and anyone seeking matched intake and HVAC filtration to preserve engine breathing and improve passenger air quality without complicated modifications. Always verify part numbers and fitment against your vehicle, and follow safe maintenance procedures when replacing filters.
