The Engine Air Filter (OEM TA81‑1109210) is an essential component of the engine air intake system used in BYD Leopard 5 (Bao 5) and Leopard 8 hybrid SUVs. The filter ensures that clean air enters the engine by trapping dust, sand particles, and airborne contaminants before they reach the combustion chamber.

The filter typically uses high‑efficiency pleated filtration paper combined with a durable rubber sealing frame, which allows proper airflow while maintaining excellent filtration performance. This design helps protect critical engine components such as the turbocharger, intake valves, and hybrid combustion engine system from contamination and premature wear.

Vehicles operating in Qatar and GCC environments are regularly exposed to desert sand, airborne dust, and extreme temperatures. These conditions can quickly clog engine air filters and reduce engine efficiency. Regular replacement of the air filter helps maintain proper air‑fuel mixture, improves fuel efficiency, and protects the engine from damage.

The air filter is typically installed inside the engine air intake housing located in the engine bay, allowing quick and straightforward replacement during routine vehicle maintenance.

Common symptoms of a clogged air filter include:

• Reduced engine performance
• Increased fuel consumption
• Slow throttle response
• Excessive dust in the intake system

Replacing the engine air filter helps restore proper airflow and maintain optimal engine performance.

⚠️ Always verify vehicle compatibility using the VIN (Vehicle Identification Number) before purchasing to ensure correct fitment.
