Description
The Verus Engineering Hood Louver Kit for the Ford Focus RS/ST MK3 is designed to reduce underhood heat and pressure while improving overall cooling and aerodynamic performance. By improving airflow out of the engine bay, the louvers help increase airflow efficiency through the radiator and charge air cooler, improving cooling stack efficiency during demanding driving.
Reducing pressure buildup beneath the hood also helps decrease front-end lift, providing a slight increase in front-end downforce for improved aerodynamic performance.
During development, Verus Engineering utilized 3D scan data and CFD analysis to strategically position the louvers in low-pressure areas of the hood. The design follows the OEM hood contours while retaining as much of the factory structural material as possible, helping maintain hood rigidity and providing an integrated appearance.
The Verus Engineering Hood Louver Kit is purpose-built for MK3 Focus RS and ST owners seeking a tested solution for improved engine-bay cooling, airflow management, and front-end aerodynamic performance.

Aerodynamic Science
Verus Engineering used CFD analysis to identify low-pressure areas on the Focus RS/ST hood where the louvers could operate most effectively. The louver geometry was also developed using scan data to follow the OEM hood's body lines while minimizing the amount of structural material that must be removed.
By evacuating hot air from the engine bay and allowing cooler air from the radiator and grille area to enter, the louvers help improve the pressure differential across the cooling stack. This can improve airflow through the radiator and charge air cooler, helping manage underhood temperatures during demanding driving.
The louvers also reduce pressure buildup beneath the hood. Lower underhood pressure reduces front-end lift, providing an aerodynamic benefit that can contribute to increased front-end downforce.
Installation
The kit includes dedicated cut-out templates and all required installation hardware. The stainless clinch stud and nut system allows the louvers to be removed when cleaning or servicing the vents.
