What does the inlet gasket do?

The inlet gasket serves as a seal between the intake manifold and the engine block, preventing air and fuel leaks in the intake system. It ensures that the correct air-fuel mixture enters the combustion chamber, which is essential for optimal engine performance and efficiency. A properly functioning inlet gasket also helps maintain proper engine vacuum and prevents contaminants from entering the engine. If the gasket fails, it can lead to engine performance issues, such as rough idling or reduced power.
