1/4" Open Tip Thermocouple only - (2.10m) 82-1/2" Long Length: 2.10m (82.5")

Overview

Professional-grade 1/4" open tip thermocouple delivering precise exhaust gas temperature monitoring for serious engine builds. At 2.10 metres long, this sensor provides the reach needed for complex exhaust manifold installations whilst maintaining the fast response times critical for boost control and engine protection strategies.

Why You Need This

EGT monitoring isn't optional in high-performance builds—it's insurance against catastrophic engine failure. This thermocouple's open tip design responds in under a second to temperature changes, giving your Haltech ECU the real-time data needed for knock protection, boost control, and fuel map safety limits. We see too many rebuilt engines that could have been saved with proper EGT monitoring, particularly on turbo LS swaps pushing over 600hp or RB26 builds running aggressive timing maps.

The 2.10-metre cable length suits everything from tight SR20DET engine bays to sprawling LS truck manifolds where the ECU mount is distant from the exhaust. The 1/4" diameter strikes the perfect balance—robust enough for trackday abuse yet small enough to weld into manifold bungs without compromising flow. Unlike cheaper thermocouples that drift over time, this unit maintains calibration accuracy even after thousands of heat cycles, essential when your engine protection strategies rely on precise temperature thresholds.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range including Elite 550/750/1000/1500/2000/2500, Nexus R3/R5, and Rebel ECUs. Connects directly to any spare analogue input when paired with appropriate thermocouple amplifier. Contact our team to confirm the correct amplifier module for your specific ECU variant.
