A modification found on some Toyota Tundra models, this component is typically mounted on the vehicle’s hood and is designed to channel airflow to the engine. Its presence often suggests a performance-oriented trim level or an aftermarket customization. For instance, some Tundra models may feature this element as part of a sport package, adding to the vehicle’s aggressive styling.
The addition can contribute to enhanced engine cooling, potentially improving performance, especially under demanding conditions. Historically, such features were primarily functional, directly feeding air into carburetors or early fuel injection systems. While some modern implementations are purely aesthetic, they evoke a sense of power and ruggedness associated with high-performance trucks.
