Restore smooth and reliable performance to your Nissan Silvia S14 SR20DET with Terra Firma Automotive’s New Genuine Idle Air Control Valve Assembly (AAC). This factory-fresh unit is a critical component of the S14’s air control system, ensuring optimal idle stability under all driving conditions. Over time, original valves can wear, stick, or fail, leading to frustrating issues such as stalling under boost, low idle during cold starts, or erratic idle behavior.
Sourced directly from Nissan and delivered brand new in the box, this OEM AAC valve offers the exact fit, finish, and performance the SR20DET engine requires. Unlike used or aftermarket replacements, a genuine Nissan valve ensures precise airflow management and compatibility with factory engine control settings, helping your S14 maintain peak reliability and drivability.
With these units becoming increasingly rare, Terra Firma Automotive is proud to offer one of the few remaining opportunities to secure this essential component. Whether you are restoring a stock example or maintaining a high-performance build, replacing a worn idle air control valve with a genuine Nissan part is a smart investment in both performance and longevity. Keep your SR20DET-powered Silvia running as it should—smooth, consistent, and ready for the road or track.
