51747200765 Radiator Duct | Thermal & Aerodynamic Optimization

Engineered for optimized thermal management in 2012-2015 5 Series Gran Turismo models, the 51747200765 Radiator Duct features injection-molded PP-TD40 material with integrated airflow vanes. The structural ribbing pattern matches factory radiator support contours while improving directional airflow by 28% compared to standard designs. Precisely positioned mounting tabs align with original equipment fastening points from the crash bar to the front carrier module.

Aerodynamic shaping reduces turbulent air recirculation behind the kidney grilles, maintaining consistent cooling system pressures. The UV-resistant compound withstands underhood temperatures up to 130°C while resisting oil/fuel vapors. Compatible with both N63 and N55 engine configurations, this duct maintains 9.5mm clearance from moving suspension components during full steering articulation.
