This product is a multi-brand universal idle air control valve originally designated as 90512528 (GM/Opel OEM number) and 0280140548 / 0280140577 (Bosch standard numbers), while also being fully compatible with 08265551 and 90469595 OEM references. This part was adopted by GM, Opel, Vauxhall, and Holden as the standard idle control actuator for various gasoline-powered vehicles produced between 1994 and 2003.

The valve helps maintain smooth engine operation during idle conditions, especially under cold start, air-conditioning load changes, or steering and electrical load variations. It effectively reduces common idle-related issues such as RPM fluctuation, engine stalling, and rough idle behavior.
