Standard Motor Products AC158T Fuel Injection Idle Air Control Valve

The Standard Motor Products AC158T is a fuel injection idle air control valve designed to regulate airflow and maintain smooth idle performance in fuel-injected engines. This precision-engineered component controls the amount of air that bypasses the throttle plate, allowing the engine control module to maintain optimal idle speed under varying conditions.

Key Features:

• High-strength stepping motor produces maximum output torque for reliable performance
• Shielded ball bearing design resists environmental contaminants for extended service life
• Manufactured with high-grade materials to OEM specifications for direct-fit replacement
• Compatible with both throttle body and multi-port fuel injection systems
• Load tested to ensure the actuator delivers force greater than actual load requirements
• Undergoes complete quality control throughout the manufacturing process

Standard Motor Products idle air control valves help maximize fuel efficiency and engine power by ensuring proper idle speed regulation. This valve opens a small bypass circuit around the throttle, with the engine computer controlling airflow to increase or decrease idle speed as needed. A properly functioning IAC valve is essential for smooth engine operation and preventing rough idle or stalling conditions.
