- Ensure the engine is off and the battery is disconnected before starting.

- Identify the small, in-line air filter connected to the IAC valve's air hose.
- Carefully disconnect the hoses from the old filter and remove it. Note the orientation.
- Install the new IAC filter, ensuring it is oriented correctly and connections are secure.
- Reconnect the battery, start the engine, and let it idle for several minutes to allow the ECU to adjust. Check for a stable idle RPM.
Troubleshooting & FAQ
How do I know if my IAC filter is clogged or failing?
Common signs of a clogged IAC filter include rough or unstable idling, frequent stalling at low RPMs, or a "Check Engine" light. The filter restricts airflow to the IAC valve, preventing it from accurately managing idle speed.
What is the function of this filter?
The Idle Air Control (IAC) filter is a small air filter that cleans the air being drawn into the IAC valve. This prevents dust and debris from entering the valve and engine, ensuring precise idle speed regulation.
Can I clean and reuse the old filter?
It is not recommended. These filters are designed for replacement. Cleaning may not remove all trapped micro-particles and could damage the filter media, leading to poor performance or engine contamination.
What is the recommended replacement interval for an IAC filter?
Replacement intervals vary based on operating conditions (e.g., dusty or saltwater environments). It's good practice to inspect the filter annually and replace it if it appears dirty or as part of your engine's routine service schedule.
