Coralfly Air Filter (equivalent to OEM 17801-21050) is a reliable filtration element specifically designed for one of Toyota's most popular engine families, where fuel efficiency and intake cleanliness are paramount.

Description and Characteristics:

• Purpose: Protects the engine from fine dust, pollen, and other contaminants. Effective air purification prevents fouling of the throttle body and sensors, ensuring stable motor operation.

• Compatibility: Optimized for Toyota Corolla (2009–2016 models, E150, E170, E180 chassis) with 1.3L, 1.6L, and 1.8L engines. It is also widely used in Toyota Auris, Yaris, Avensis (T27), and Prius models.

• Material: Uses a dense filter media with a special fiber structure that offers high dirt-holding capacity without restricting the necessary intake air volume.

• Construction: The precise shape of the panel filter and high-quality sealant ensure an airtight fit in the housing, eliminating unfiltered air "leakage" even under high vibration.

Technical Specifications:

• OEM Number: 17801-21050 / 17801-0D060

• Housing Type: Panel (rectangular)

• Advantages: Operational stability in various climatic conditions, easy replacement without special tools, and high degree of protection for the piston group.
