Overview Haltech's 1/4" open tip thermocouple delivers precision temperature monitoring for your high-performance build, measuring exhaust gas temps with the accuracy your tune demands. At 1.52m (60") length, it reaches awkward header locations whilst keeping the sensor clear of heat soak and vibration damage. Essential for turbo builds, race engines, and any application where knowing your EGTs prevents expensive catastrophic failure. Technical Specifications Part Number: HT-010868 Probe Diameter: 1/4" (6.35mm) Cable Length: 1.52m (60") Tip Design: Open tip for fast response Temperature Range: Up to 1100°C continuous Why You Need This EGT monitoring isn't optional on serious builds. Whether you're running a single turbo 2JZ pushing 500bhp or a twin-scroll setup on an RB26, exhaust gas temperatures tell the real story of what's happening in your combustion chambers. Run too lean under boost and you'll see EGTs climb rapidly before detonation destroys pistons. This 1/4" open tip design responds faster than closed-tip alternatives, giving you real-time data when milliseconds matter during aggressive tuning or track sessions. The 1.52m cable length is crucial for proper installation. Short cables force you to mount the thermocouple too close to the turbo or exhaust manifold, where heat soak gives false readings and cable insulation fails. This length lets you position the probe in the optimal location — typically 6-12 inches downstream from the exhaust port — whilst routing the cable safely away from extreme heat zones. We see too many failed installs where builders compromise on probe placement due to inadequate cable length. ECU & System Compatibility Direct connection to Haltech Elite 550, 750, 1000, 1500, 2000, and 2500 ECUs via dedicated thermocouple inputs. Also compatible with Nexus R3 and R5 systems for comprehensive engine monitoring integration. Note that some ECU variants may require specific input conditioning — our technical team can confirm exact wiring requirements for your particular Haltech system and build specification. What's in the Box 1x 1/4" Open Tip Thermocouple with 1.52m cable Bare wire termination for ECU connection Complete Your Build Most customers installing EGT monitoring also require proper bung welding in their exhaust system — we can recommend trusted fabricators in your area. Consider adding multiple thermocouples for comprehensive monitoring on multi-cylinder turbo setups, particularly useful on RB26 or 2JZ-GTE builds where individual cylinder monitoring prevents single-pot disasters. Our technical team keeps UK stock of complementary Haltech sensors and can advise on complete monitoring packages tailored to your specific engine platform and performance goals.
