Our factory specializes in the manufacturing of high-quality automotive underbody components and thermal management parts. The BYD Destroyer 05 Radiator Baffle Plate (also known as underbody front air deflector, cooling air guide, radiator lower splash shield, or front bumper lower cover) is a precision-engineered OE-grade replacement part designed specifically for the BYD Destroyer 05 (2022–present, DM-i version). As a professional automotive parts manufacturer, we integrate advanced injection molding technology, aerodynamic design capabilities, and strict quality control to deliver products that meet or exceed original equipment standards.

The radiator baffle plate is an important part of the vehicle‘s cooling system, which is also known as an underbody air deflector, cooling air guide, or front bumper lower cover. Installed underneath the front bumper, this component bridges the gap between the radiator assembly and the underbody, directing incoming airflow precisely through the radiator core for maximum cooling efficiency. The DM-i hybrid powertrain, with its 1.5L Xiaoyun engine producing up to 81 kW (109 hp), relies on precise airflow management for optimal thermal regulation. In addition to its primary cooling function, this part also serves as an underbody splash shield, protecting the radiator, intercooler, and front chassis components from road debris, stones, and water ingress. When the original baffle plate becomes cracked, damaged, or missing due to road impacts or aging, the engine may face overheating risks, increased fuel consumption, and aerodynamic drag. Our premium replacement baffle plate restores factory-fresh airflow direction, cooling efficiency, splash protection, and aerodynamic balance.
