The IAC (Idle Air Control) valves we supply regulate auxiliary air flow to maintain stable engine idle under varying conditions. These solenoid-actuated valves feature a pintle design with electromagnetic coils that respond within 30ms to ECU signals. The linear flow characteristic (0–100% duty cycle) allows precise idle speed control, and the Teflon-coated valve stem reduces friction for smooth operation. Compatible with OBD-II systems, they self-adapt to carbon buildup through learned offset values. We offer valves for both port fuel injection and direct injection engines, with part numbers matching OEM specifications for Toyota, Honda, Volkswagen, and more. Each valve is tested for flow vs. duty cycle linearity and coil resistance before packaging.
