The AAC valve gasket is a small die-cut piece that seals the idle air control valve to the intake. Once the valve is removed for cleaning or service, the original gasket is usually torn or flattened and no longer seals. A leak here causes idle fluctuations and can set a lean condition at low load. The factory Nissan part 23785-40F00 is still listed, but priced double or more over the JRE unit for just about the same part!
The JRE AAC Valve Gasket (part number 23785-JRF00) is made from the same high-quality gasket material and is die-cut to the original dimensions so it is nearly indistinguishable from the OEM piece. It replaces Nissan 23785-40F00 on the RB26DETT, RB25DET, and RB20DET. One is required whenever the AAC valve is removed.
At Terra Firma Automotive we supply this JRE AAC valve gasket so the idle air control circuit seals correctly without the higher cost of the original Nissan part. Choose Terra Firma Automotive for authentic-fit RB gaskets built for the Skyline.
