Why You Need This

EGT monitoring isn't optional on boosted applications — it's insurance against catastrophic engine damage. This thermocouple feeds critical exhaust gas temperature data to your Haltech ECU, enabling real-time monitoring and protection strategies that prevent detonation, pre-ignition, and thermal overload. The open tip design provides faster thermal response than grounded junctions, crucial for detecting rapid temperature spikes during transient conditions.

Whether you're running an RB26 conversion, turbo LS swap, or high-boost SR20DET build, positioning this probe post-turbo gives you the data needed for safe tuning. We see too many expensive engines destroyed by uncontrolled EGTs — particularly on pump fuel conversions where knock detection alone isn't sufficient protection. The 1.41m length suits most applications from compact Japanese engines to larger V8 conversions, reaching from exhaust manifold to ECU mounting positions.

ECU & System Compatibility

Compatible with all Haltech Elite series (550/750/1000/1500/2500), Nexus R3/R5, and Platinum ECUs featuring thermocouple inputs. Connects directly to designated EGT channels for seamless integration with Haltech's protection and logging systems.
