Monitoring for Duramax Owners

The Insight CTS4 provides a convenient way to keep important operating information visible while driving, towing, or monitoring vehicle performance.

Depending on vehicle compatibility, available parameters may include engine coolant temperature, transmission fluid temperature, boost pressure, engine RPM, intake air temperature, and additional engine and drivetrain information.

The CTS4 is particularly useful for drivers who want a dedicated gauge display without having to navigate through the factory instrument cluster.

Important: The Insight CTS4 is a monitoring and diagnostic device. It does not include performance tuning. Available gauges, diagnostic functions, and vehicle support vary by application. Verify compatibility with your specific year, make, model, and engine before ordering.
