Idle Air Control (IAC) Valves

The idle air control (IAC) valve is located on the throttle body of fuel-injected engines, where it works with the vehicle’s ECU to electrically regulate airflow to the engine to ensure smooth idling. We manufacture Idle Air Control Valves at our ISO/ TS16949-certified facilities in Greenville, SC, and Reynosa, Mexico, respectively. A key aspect of the manufacturing process is the load testing, which makes sure each actuator delivers a greater force than actual load.

Takeaways

  • Tested at greater than normal force to extend longevity
  • Anodized aluminum housing resists wear and tear from corrosion

    High-temp polyester coating on solenoid coil wire ensures proper function during cyclic exposure to elevated temperatures 

A Sweet Spot Category

According to our research, more than 70 million vehicles (model years 1995 through 2005) on the road today have entered “sweet spot” years for IAC repairs, which means they have an IAC that will need to be replaced soon. Choose high-quality BWD Idle Air Control (IAC) Valves to take advantage of this growing repair opportunity.
