Why You Need This

EGT monitoring isn't optional on serious turbo builds—it's insurance against catastrophic engine failure. This open tip thermocouple gives you real-time exhaust gas temperatures, critical for preventing detonation and protecting pistons, valves, and turbine wheels. Unlike cheaper alternatives, the open junction design provides lightning-fast response to temperature changes, giving you millisecond warning of dangerous conditions during aggressive tuning sessions.

We see too many builders running blind without proper EGT monitoring, then wondering why their 2JZ or RB26 build grenaded at 25psi. Whether you're pushing a stock turbo LS swap hard or running big boost through an SR20DET, this thermocouple connects directly to your Haltech's analogue inputs for seamless integration. The 1.98m cable length is perfect for routing from exhaust manifold to firewall without splicing—essential for maintaining signal integrity in high-EMI environments around ignition systems.

ECU & System Compatibility

Direct connection to analogue temperature inputs on Elite 550, 750, 1000, 1500, 2000, and 2500 ECUs, plus Nexus R3 and R5 systems. Also compatible with Haltech's dedicated WB1 and WB2 wideband controllers featuring thermocouple inputs. Contact our technical team for specific wiring guidance on your ECU configuration.

What's in the Box

• 1x K-type thermocouple with 1/4" open tip probe
