The factory MAT sensor sits near heat sources in the intake plenum, often skewing readings and leading to reduced engine performance. Relocating the sensor to cooler intake air helps the ECM deliver more accurate air/fuel and timing control—enhancing efficiency and maintaining power. Upgrade the performance of your 1985–1991 L98-powered Corvette C4 with the MAT Sensor Relocation Kit. This plug-and-play kit moves the MAT sensor to cooler ambient air near the air filter base. Installation is quick—requiring only a 7/8" hole drilled in the filter base and includes all hardware and instructions for a seamless process. It installs in approximately 30 minutes, and all-as-new readings can improve throttle response and drive quality. Made in the USA, the kit features a “mushroom” connector for reliable OEM-compatible integration.
