MSD 2937 Idle Air Control Motor for Atomic TBI System

The MSD 2937 Idle Air Control (IAC) Motor is a direct replacement component designed specifically for MSD's Atomic EFI Throttle Body Injection systems. This precision-engineered stepper motor regulates idle speed by controlling airflow bypassing the throttle plate, ensuring smooth and stable idle performance under varying engine loads and temperatures.

Key Features:

• Direct replacement IAC motor for MSD Atomic TBI units
• Precision stepper motor design for accurate idle speed control
• Controls bypass air to maintain optimal idle RPM
• Compensates for electrical loads, A/C engagement, and temperature changes
• Factory-tested for reliable performance and durability
• Essential component for proper EFI system operation

This IAC motor works in conjunction with the Atomic TBI ECU to automatically adjust idle speed, preventing stalling during cold starts and maintaining consistent idle quality as engine conditions change. Essential replacement part for maintaining the performance and driveability of your MSD Atomic EFI system.
