What Does This Part Do?

It provides a tight seal between the IAC valve and the intake manifold, preventing unmetered air leaks that cause erratic rough idling, stalling, or poor engine performance. This gasket should always be replaced when removing or replacing the IAC valve (18137-77E00) to ensure a proper seal.
