Air Filter 1109-06897 Replacement Filter Element for Yutong Bus

Part Number: 1109-06897 is a premium-grade Air Filter Element or Air Cleaner Assembly specifically engineered for use in Yutong ZK6122, ZK6127, ZK6128, and ZK6118 series 11–12 meter luxury coaches and highway buses. As a critical component of the engine intake system, this filter plays a vital role in protecting high-output diesel engines — such as Weichai WP10/WP12, Cummins ISL/ISME, and Yuchai YC6L — from harmful airborne contaminants like dust, soot, and debris. Constructed with advanced imported or high-performance domestic nano-composite filtration media, it delivers exceptional dirt-holding capacity, low airflow resistance, and long service life under demanding operating conditions. Featuring a robust polyurethane (PU) end cap seal and optimized pleat design, it ensures reliable sealing across extreme temperature ranges and maintains engine performance, fuel efficiency, and longevity. Recognized as a core OEM component in China’s commercial coach fleet, 1109-06897 meets the highest standards for durability and filtration efficiency in 2026.
