Understanding the Motorcraft CX1866 Idle Air Control Valve
The Motorcraft CX1866 is an OEM-grade Idle Air Control (IAC) Valve used in several Ford models, including the Focus, Escort, and ZX2. It regulates airflow into the engine during idling, ensuring smooth RPM levels. Many buyers wonder — cx1866 does it come eith gasket — since the gasket plays a key role in preventing air leaks that can cause rough idling or stalling.
How It Works in Your Engine
When you start your vehicle, the idle air control valve adjusts the airflow automatically. It communicates with your car’s ECU to balance air and fuel for stable idle. If the gasket is missing, that precision balance can break, leading to erratic RPMs or engine hesitation.

Why the Gasket Matters in CX1866 Installation
If you’ve ever replaced an idle air control valve, you know how crucial that tiny gasket can be. For proper installation, the gasket creates a firm seal between the throttle body and valve housing. Without it, air may enter the manifold unregulated, causing performance loss. This is why mechanics often ask, cx1866 does it come eith gasket, before placing an order.
The Risk of Missing Gasket
Installing the CX1866 without a gasket can trigger idle surges or even a check engine light. The seal ensures pressure consistency and prevents vacuum leaks — essential for modern engines’ precise air control.
