The original factory replacement high-flow air filter for family SUVs and MPVs such as Toyota RAV4 / Previa/Estima / Alphard, featuring a four-layer viscous cotton fabric medium to achieve a balance of precise filtration and high intake efficiency, supports repeated cleaning and regeneration, and does not require modification to enhance the power response and throttle sensitivity of 2.0L/2.4L inline four-cylinder engines (including 2AZ-FE), while being compliant and not affecting vehicle warranty, and is compatible with the original single intake air filter box.
