Standard Ignition AC6 Idle Air Control Valve

Idle Air Control Valve for GM V8 Applications

Standard Ignition AC6 is an idle air control valve built for precise idle-speed management on select Chevrolet and GMC trucks, vans, and Suburban models. It uses a polymer-blended, isotropic neodymium/iron/boron magnet and a high-strength stepping motor to control pintle movement and airflow with consistent response.

With included gasket and hardware, AC6 is a direct-fit service part for many 1987-1998 Chevrolet and GMC applications, including Chevrolet C2500, K2500 Suburban, and GMC G3500 models. The Standard Ignition AC6 is engineered for stable idle control where accurate airflow regulation matters.

Key Features

• Idle Air Control Valve for fuel-injected GM applications
• Polymer-blended neodymium/iron/boron magnet for accurate pintle control
• High-strength stepping motor for strong actuator output
• Shielded ball bearing helps resist environmental contamination
• Load-tested actuator for added durability and consistent performance
• Includes gasket and hardware
• 1 port and 4 terminals

Detailed Description

Standard Ignition AC6 is designed to regulate bypass air at idle so the engine can maintain a steady speed under changing load conditions. This matters on Chevrolet C1500, C2500, K2500, K3500, P30, and GMC C2500, K2500, P3500 platforms where idle quality affects drivability, cold starts, and accessory load response. The valve’s stepping motor and magnet assembly are built for accurate pintle movement, while the shielded bearing helps protect the motor from contamination over time.

This part cross-references Delphi CV10027 and Walker Products 215-1009 for the same application. Standard Ignition AC6 is a practical replacement choice when servicing GM idle air control systems on 1987-1998 Chevrolet and GMC vehicles.

What It Helps Address

• Unstable or fluctuating idle speed
• Stalling when coming to a stop
• High idle after startup or during warm-up
• Poor idle recovery when accessories are switched on
• Idle control issues caused by a worn pintle or actuator

Installation Notes and Tips

Verify the 10mm pintle application notes before installation, since some listed vehicles use a primary application and others note an auxiliary air valve configuration. Clean the throttle body and mating surfaces before installing the new valve, and replace the gasket during service. Confirm the 4-terminal connector style and 1-port layout match the original part on your Chevrolet or GMC application.

Quality Assurance

Standard Ignition manufactures this idle air control valve with high-grade materials and load-tested actuator components for consistent operation and service life. The design focuses on accurate airflow control and resistance to contamination in demanding underhood environments.
