1/4" Open Tip Thermocouple only - (1.18m) 46-1/2" Long Length: 1.18m (46.5")

Overview

This 1/4" open tip thermocouple delivers precise exhaust gas temperature monitoring for your Haltech EFI system, crucial for protecting turbocharged engines and maximising performance tuning accuracy. At 1.18m length, it's perfectly sized for most engine bay configurations whilst providing the rapid response times essential for real-time EGT monitoring during aggressive tuning sessions.

Technical Specifications

• Part Number: HT-010865
• Probe Diameter: 1/4" (6.35mm)
• Cable Length: 1.18m (46.5")
• Tip Configuration: Open tip design
• Response Time: Ultra-fast thermal response

Why You Need This

Exhaust gas temperature monitoring isn't optional on serious builds — it's insurance against catastrophic engine failure. This open tip thermocouple provides the fastest possible response to temperature changes, critical when you're pushing boost levels on 2JZ-GTE builds, RB26 conversions, or any turbocharged application where EGT spikes can destroy pistons in seconds. The 1/4" diameter strikes the perfect balance between structural integrity and thermal response, whilst the open tip design eliminates the thermal lag you get with sheathed sensors.

We've seen too many expensive rebuilds that could have been prevented with proper EGT monitoring. Whether you're running E85 on a built LS motor, dialling in boost on an SR20DET swap, or pushing the limits on a Honda K-series turbo build, this thermocouple gives your Haltech ECU the real-time data needed to protect your investment. The 1.18m cable length works perfectly for most engine bay layouts without requiring extensions that can introduce electrical interference.

ECU & System Compatibility

Compatible with all Haltech Elite ECUs (550, 750, 1000, 1500, 2000, 2500) and Nexus R3/R5 systems equipped with thermocouple inputs. Also works with standalone Haltech WB1 and WB2 wideband controllers featuring EGT monitoring capabilities. Contact our technical team to confirm input configuration for your specific ECU setup.
