2-1/16 Pyrometer Gauge - GM Diesel Truck

The 2-1/16 Pyrometer Gauge from AutoMeter is a dedicated exhaust gas temperature (EGT) monitoring instrument engineered specifically for GM Diesel truck owners and serious diesel mechanics. Monitoring exhaust temperature is critical for diesel engine health and longevity, as it reveals combustion efficiency, fuel economy trends, and early signs of engine stress or boost creep.

This gauge sits at the heart of any informed diesel tuning or maintenance program, providing real-time data that helps prevent costly engine damage from excessive heat. AutoMeter's 2-1/16 pyrometer features precision thermal sensing technology designed to handle the demanding thermal environment of diesel exhaust systems. The compact 2-1/16-inch gauge face integrates seamlessly into factory or custom dashboard installations.

Diesel truck owners running stock or modified engines benefit immediately from EGT monitoring, as it identifies when combustion is becoming inefficient or when turbo boost pressures are climbing too high. Mechanics performing diesel service, diagnostics, or custom tuning rely on pyrometer data to validate engine calibration and catch problems before they escalate.
