X-Series Temperature Gauge 100-300F

The X-Series Temperature Gauge 100-300F from AEM Electronics is a professional-grade analog engine temperature monitor designed for serious enthusiasts and mechanics who demand precision coolant tracking. This gauge is essential for tuning street engines, monitoring high-performance builds, or diagnosing thermal issues on modified vehicles, helping to prevent catastrophic overheating.

This AEM temperature gauge reads across a 100–300°F span, covering the full operational envelope from cold-start diagnostics to high-heat track sessions. The analog needle display responds dynamically to real-time coolant temperature shifts, allowing users to spot rising trends before electronic circuits trigger limp-mode. Note that a sender is required for operation and is sold separately.

Mechanics and engine builders rely on the X-Series Temperature Gauge 100-300F across naturally aspirated, supercharged, and turbocharged platforms, making it a versatile tool for ensuring cooling system reliability. Its compact design allows for straightforward installation on custom dash panels, pillar mounts, or center console pods without adding significant bulk or weight.
