Holstein 2IAC0059 Idle Air Control (IAC) Valve

The Holstein 2IAC0059 Idle Air Control Valve is a direct OE replacement for a critical engine management component, engineered to restore factory idle performance and eliminate rough or erratic idling, stalling, and hard starts.

The idle air control (IAC) valve is an electrically operated device that receives signals from the vehicle's Engine Control Unit (ECU). It regulates the amount of air bypassing the throttle plate at idle, allowing the ECU to maintain a stable minimum RPM regardless of changes in engine load — sometimes referred to as an anti-stall feature.

Key Features:

• Direct OE replacement designed for precise fit, form, and function
• Precision-engineered to exactly duplicate the operation of the original equipment component
• Manufactured with premium, heat-resistant materials built to withstand high engine operating temperatures
• Gasket and fasteners included where applicable for a tight, leak-proof installation
• Built to match or exceed OEM specifications for smooth, reliable idle performance
• Backed by Holstein's 3-Year / 36,000-Mile Warranty

Holstein Parts sources components from the same factories that supply original equipment manufacturers, combining rigorous quality control and cataloging verification to ensure proper fitment. With a sub-1% failure rate across their sensor and valve product lines, the 2IAC0059 delivers dependable, long-term performance at an accessible price point.
