Idle Air Control Unit — precise idle airflow management, durable construction, exact part-match Key benefits Optimizes engine idle performance by allowing precise adjustment of the idle air stream, improving idle stability and responsiveness. Built for long service life: constructed from high-quality materials to resist wear and provide reliable operation over time. Guaranteed fit for applications that use part numbers 377500-800-0000 and 39140-E05-0000, minimizing fitment issues and installation time. Designed for 12-volt electrical systems, compatible with standard 12-V vehicle wiring. What this product does for you Stabilizes engine idle speed to reduce rough idling and minimize the chance of stalling during idle or low-speed operation. Preserves consistent air metering at idle, which supports smoother cold starts and steadier low-RPM performance. Replaces worn or failing idle control components with a unit that meets the same part-number specifications for fit and function. Key attributes Function: Precise control of idle airflow to optimize motor performance at idle and low RPM. Compatibility: Meets part numbers 377500-800-0000 and 39140-E05-0000 for direct compatibility with the corresponding vehicle applications. Voltage: Rated for 12 V electrical systems. Durability: Engineered with durable materials to resist wear and extend service life. Practical use scenarios Replace a failing idle control unit that is causing rough idle or intermittent stalling to restore smooth engine operation. Routine maintenance or part refresh when refurbishing an engine or servicing intake components on a vehicle using the listed part numbers. Fleet or workshop repairs where reliable, part-number-correct replacements are required to reduce downtime and repeat service calls. Installation and compatibility notes Confirm the vehicle’s required part number (377500-800-0000 or 39140-E05-0000) and 12-V electrical system before purchase to ensure proper fitment. Intended as a direct replacement for systems that specify these part numbers; follow vehicle manufacturer instructions for removal, installation, and any required calibration. Reliable, part-number-matched idle control designed to restore stable idle performance and long-term durability without compromising compatibility.
