A raised component, typically constructed from fiberglass or carbon fiber, affixed to the hood of a vehicle, primarily for the purpose of channeling airflow to the engine compartment. These components are often observed on high-performance automobiles and racing vehicles as a means to improve engine cooling and, in some designs, contribute to increased induction efficiency. The design and dimensions can vary considerably depending on the vehicle application and the desired performance characteristics.
The adoption of such a feature provides multiple advantages. Effective management of engine temperature contributes to consistent and reliable engine operation, especially under demanding conditions. Some designs are engineered to capture high-pressure air, forcing it into the intake system, which can lead to improved power output. Historically, these additions were employed on production vehicles to homologate designs for racing series, establishing a direct link between road cars and motorsport technology.
