The K&N KNA-2443 engine air filter is engineered as a high-performance, washable replacement for your vehicle's standard disposable air filter. Its long-life construction is rated for up to 18,000 miles of use, offering extended service intervals. Installation is straightforward, as the K&N KNA-2443 is designed to drop directly into your factory airbox without requiring any modifications. This makes it a simple and cost-effective upgrade for your vehicle's air intake system. The filter media is specially treated to provide excellent filtration while allowing for improved air intake. This K&N air filter is compatible with a wide range of Toyota, Lexus, and Mitsubishi vehicles, including models like the Highlander, RAV4, Sienna, Avalon, Camry, Lexus ES 350, NX300, and RX350.
