A component designed to enhance engine performance by relocating the air intake away from the engine bay, facilitating cooler air entry. Cooler air is denser, containing more oxygen per unit volume, which can lead to more efficient combustion. This is often achieved by positioning the intake filter in a location where ambient air is readily available, such as behind the bumper or near the wheel well. Modifications of this type are frequently pursued by automotive enthusiasts seeking improved throttle response and slight horsepower gains.
The implementation offers potential benefits regarding engine efficiency. Historically, performance enhancements for automobiles have involved modifications to the intake and exhaust systems. Cooler air intake is a common method to improve engine performance because the engine can generate additional power. The systems impact varies depending on the specific engine design and other modifications present. Factors such as filter quality and intake tube design also affect overall effectiveness.
