Why You Need This

Exhaust gas temperature monitoring is critical for any serious build, particularly turbocharged applications where cylinder head cracking from excessive EGTs can destroy an engine in minutes. This open-tip design provides the fastest response time available — crucial when your ECU needs real-time data for boost control and ignition timing protection strategies. We've fitted these on everything from high-boost 2JZ builds to RB26 GT-R conversions where pre-turbo EGT monitoring prevents catastrophic overheating during sustained track sessions.

The 1.75m cable length suits most engine bay installations without requiring extensions that introduce measurement errors. Unlike cheaper thermocouples that drift over time or fail under thermal cycling, this unit maintains accuracy across the full temperature range. Whether you're monitoring individual cylinder EGTs on a built SR20DET or tracking intercooler efficiency on an LS turbo conversion, reliable temperature data is non-negotiable for both performance optimisation and engine protection.

ECU & System Compatibility

Compatible with all Haltech Elite series ECUs (550/750/1000/1500/2000/2500) and Nexus R3/R5 systems featuring analogue temperature inputs. Also works with standalone temperature monitoring systems and third-party ECUs accepting K-type thermocouple inputs.
