A-Premium Idle Air Control Valve for Dodge Jeep Ram — 4‑Pin IAC, Direct Replacement for 4.7L/3.7L Engines

The A-Premium Fuel Injection Idle Air Control Valve with a 4-pin plug is a direct-replacement idle air control unit that regulates bypass airflow to stabilize and smooth engine idle on compatible Dodge, Jeep, and Ram models.

This robust replacement idle air control (IAC) valve is built to match factory fit and function for a range of late‑1990s and early‑2000s Chrysler-based vehicles. Designed as a four-terminal blade-plug component, it takes the place of worn or failing valves that can cause rough idle, stalling at low speed, or inconsistent rpm. A-Premium backs this part with a one-year unlimited-mileage guarantee and ships it securely in a box for straightforward installation.

How does this idle air control valve affect idle and drivability?

The valve meters the airflow that bypasses the throttle plate when the throttle is closed, so the engine management system can hold a steady idle. Replacing a failing IAC valve often removes rough or hunting idle behavior and stabilizes rpm during accessory load or temperature changes.

• Controls bypass air to keep idle steady under load changes
• Reduces hunting idle and minimizes low‑speed stalling
• Improves consistency after cold starts or when A/C engages
