Definition
A car diffuser is an aerodynamic component, typically fitted to the rear bumper of a vehicle. It is designed to manage the airflow exiting from underneath the car.
Why it matters (in Poovi’s context)
Improves the vehicle’s aesthetic appeal by giving it a sportier or more aggressive look, and can potentially offer minor aerodynamic benefits.
