Nissan Silvia Idle Speed Control Motor Gasket - Radium Engineering - IACV Gasket - `94-`02. This gasket is a direct-fit sealing piece for the Radium Engineering Idle Air Control Valve on S14/S15 SR20DET applications from 1994–2002, designed to replace worn or damaged IACV seals.

Manufactured from a composite of Kevlar and Nitrile rubber, the gasket offers resistance to fuel and oil exposure common in engine bay environments. The CNC knife-cut process produces consistent edges and thickness for a reliable seal against the IACV and intake flange. Ideal for enthusiasts performing maintenance or customization on Silvia platforms, this gasket helps prevent air and fluid leaks where the idle speed control motor mounts.
