The C14 inlet is a type of air intake system commonly used in various engines, particularly in automotive applications. It is designed to optimize airflow into the engine, enhancing performance and efficiency. By allowing a controlled amount of air to enter, the C14 inlet helps improve combustion, which can lead to better fuel economy and increased power output. This inlet system is often part of a larger assembly that includes components like air filters and throttle bodies. Proper maintenance of the C14 inlet is essential for ensuring that the engine operates smoothly and efficiently, contributing to the overall longevity of the vehicle.
