Product Details
The Honda OEM Idle Air Control Valve (IACV) is a genuine factory replacement designed for the 2002-2006 Acura RSX Type-S and 2002-2005 Honda Civic Si equipped with K20 engines. This valve regulates airflow bypassing the throttle plate, allowing the engine's ECU to maintain a smooth, consistent idle under varying operating conditions.
A failing or contaminated idle air control valve can cause fluctuating RPM, rough idling, stalling, or unusually high idle speeds. Replacing a faulty valve helps restore proper idle control, improve cold-start operation, and maintain reliable engine performance.
Manufactured to Honda's original equipment specifications, this idle air control valve provides precise fitment and dependable operation for factory repairs, K-Series engine rebuilds, and compatible engine swaps.

KSERIESPARTS Doesn't mess around at all. They ship out your products really fast. The AIC valve I bought works great! Nothing like buying OEM parts.
