Overview This precision 1/4" open tip thermocouple delivers accurate EGT monitoring for your Haltech EFI system, essential for protecting high-performance engines under boost or extreme load conditions. At 0.95m length, it's perfectly sized for most engine bay installations whilst providing the rapid response needed for real-time exhaust gas temperature monitoring and closed-loop tuning. Technical Specifications Part Number: HT-010863 Probe Diameter: 1/4" (6.35mm) Cable Length: 0.95m (37.5") Tip Configuration: Open tip for fast response Temperature Range: Up to 1200°C continuous operation Connection Type: Bare wire termination for Haltech EGT inputs Why You Need This EGT monitoring isn't optional on serious builds — it's insurance against catastrophic engine damage. Whether you're running a turbo LS swap pushing 20psi, an RB26 on E85, or a 2JZ build chasing big numbers, exhaust gas temperatures tell the real story of what's happening inside your combustion chambers. The open tip design provides faster thermal response than sheathed probes, crucial when monitoring rapid temperature changes during aggressive tuning or track use. This 1/4" diameter strikes the perfect balance between durability and response time. Smaller probes break easily in high-vibration applications, whilst larger units respond too slowly for effective closed-loop EGT control. The 0.95m length suits most engine installations from Escort RS builds to modern drift cars, reaching from exhaust manifold to ECU mounting points without excessive cable routing. We've used these extensively on everything from trackday SR20DETs to big-turbo BMW applications — they're proven reliable in the harshest conditions. ECU & System Compatibility Compatible with all Haltech Elite ECUs (Elite 550, 750, 1000, 1500, 2000, 2500) and Nexus range (R3, R5, Rebel) featuring dedicated EGT inputs. Also works with Platinum series ECUs when used with appropriate EGT amplifier modules. Contact our technical team to confirm your ECU's EGT input requirements and wiring specifications.
