The BD Diesel High Idle Control (1036609) is a convenient and practical upgrade designed specifically for 2003-2004 Ford Powerstroke 6.0L engines. This plug-and-play module allows users to increase engine idle speed, which is particularly useful in cold weather conditions or when running auxiliary equipment that requires higher idle RPMs. By raising the idle speed, the High Idle Control helps warm up the engine faster, improves charging output, and maintains proper function of aftermarket accessories. Installation is simple and non-invasive, requiring no cutting or splicing of factory wiring. Built with reliability in mind, the BD Diesel High Idle Control is a smart addition for Powerstroke owners looking to enhance vehicle performance and functionality during idle conditions.
