About This Product

The S&S Cycle idle air control motor is a precision-engineered replacement for the IAC module found on fuel-injected Harley-Davidson engines. This motor is responsible for managing the engine's idle speed by adjusting the airflow when the throttle plate is closed. S&S manufactures this component to strict standards to ensure responsive and accurate idle stabilization, which is particularly important for engines with performance modifications that may have sensitive idling requirements. This unit provides the reliability needed to prevent stalling and ensure a smooth, consistent idle in all weather conditions. Sold individually.

Manufacturer part number: 55-5085.
