Radium 20-0162 IACV Spacer Kit – SR20DET S14 / S15

Create clearance for top-feed fuel rail setups on your SR20DET with the Radium Engineering 20-0162 IACV Spacer Kit. This idle air control valve spacer is compatible with the SR20DET engine commonly found in Nissan Silvia S14 and S15 chassis.

The OEM 2-bolt IACV bypass hard line is replaced by this anodized aluminum spacer kit to gain clearance for top-feed fuel rails. Radium includes an anodized aluminum barb adapter and PCV hose to reroute the charge pipe hose externally to the intake manifold.

This kit is a clean solution for SR20DET builds using top-feed fuel rail conversions where the factory IACV bypass hard line interferes with fuel rail clearance.
