1/4" Open Tip Thermocouple only - (1.87m) 73-1/2" Long Length: 1.87m (73.5")

Overview

This 1.87m (73.5") quarter-inch open tip thermocouple delivers precise exhaust gas temperature monitoring for serious engine management. Essential for turbo builds, forced induction applications, and any performance engine where EGT data drives tuning decisions and protects expensive components from thermal damage.

Why You Need This

Exhaust gas temperature is the single most critical parameter for preventing catastrophic engine damage in turbocharged applications. This thermocouple positions directly in the exhaust stream to provide real-time EGT data to your Haltech ECU, enabling precise fuel mapping, boost control, and most importantly, component protection. Without proper EGT monitoring, you're running blind — high EGTs silently destroy turbos, melt pistons, and crack cylinder heads long before other sensors detect the problem.

The 1/4" open tip design offers faster response times than enclosed sensors, crucial when monitoring rapid temperature changes during aggressive driving or dyno tuning. At 1.87m length, this thermocouple suits most engine bay layouts from compact SR20 swaps to spacious LS conversions, with enough cable to route cleanly from exhaust manifold to ECU location. Popular fitment points include pre-turbo manifold runners for individual cylinder monitoring, or post-turbo for overall exhaust temperature trending in single-turbo 2JZ and RB builds.

ECU & System Compatibility

Direct compatibility with Haltech Elite 550, 750, 1000, 1500, 2000, and 2500 ECUs through dedicated thermocouple inputs. Also supports Nexus R3, R5, and Platinum series ECUs with appropriate input conditioning. The K-type element integrates seamlessly with Haltech's internal temperature compensation and calibration tables for accurate readings across the full operating range.

What's in the Box

• 1x Haltech 1/4" open tip thermocouple (1.87m length)
• Thermocouple connector for Haltech ECU integration
