Nissan Skyline R32 Air Regulator Valve IAC RB20

Restore factory-smooth idle performance in your Nissan Skyline R32 with Terra Firma Automotive’s New Genuine IAC (Idle Air Control) Air Regulator Valve for RB20DET and RB20DE twin-cam engines. This original Unisia Jecs OE unit is designed to precisely manage airflow during cold starts and idle conditions, ensuring stable RPMs and seamless transitions from cold to warm operation. If you're experiencing idle surging, rough idling, or engine stalls in your R32, a failing IAC valve is often the culprit.

At Terra Firma Automotive, we proudly supply only brand-new, factory-spec components—never refurbished or imitation parts. Each Air Regulator Valve comes sealed in the original Nissan packaging and delivers the reliability, fit, and function you expect from an OEM replacement. This critical valve works in coordination with your RB20 ECU to maintain correct idle speed under varying engine loads and temperatures, helping preserve drivability and engine longevity.

It’s important to note that this valve is not compatible with RB20E single overhead cam engines. This unit is intended solely for RB20 twin-cam applications in the Nissan Skyline R32 platform. As these parts become increasingly scarce, sourcing a genuine valve is key to maintaining authenticity and performance.

Choose Terra Firma Automotive to keep your Skyline running as Nissan intended. Trust in our expertise and inventory of hard-to-find, high-quality OEM components to support your restoration or performance goals. Replace your worn IAC valve today and restore proper idle control to your R32 Skyline.
