Replacement Clamp-On Thermocouple

The Replacement Clamp-On Thermocouple by Computech Systems is an essential diagnostic and engine management tool for serious automotive enthusiasts and mechanics who demand accurate real-time temperature monitoring. This precision sensor clamps directly onto exhaust manifolds, headers, or intake runners to capture critical thermal data that informs fuel mapping, ignition timing, and forced induction tuning decisions. Whether you're diagnosing lean-condition hot spots, validating intercooler efficiency, or fine-tuning a carbureted or fuel-injected engine build, reliable thermocouple feedback is non-negotiable for both street and track applications.

The clamp-on design eliminates the need for welding or threaded bungs, allowing quick repositioning across multiple measurement points without permanent modification to your engine bay. Computech Systems engineered this thermocouple for repeatability and fast response time, critical when monitoring transient conditions during acceleration or load cycling. The compact 3.75 × 1.05 × 6.05-inch form factor and lightweight 0.32 lb construction make it easy to position in tight engine compartments, while the clamp mechanism ensures stable contact and repeatable placement for consistent baseline data and comparative testing across different tuning parameters.

This replacement clamp-on thermocouple is ideal for tuners integrating Computech or third-party engine management systems that accept standard K-type or J-type thermocouple inputs. It pairs seamlessly with dataloggers, aftermarket ECUs, and portable diagnostic platforms used to validate exhaust gas temperature trends during dyno sessions, road testing, or street driving. Buy this replacement unit when upgrading sensor locations, replacing damaged probes, or expanding your multi-point temperature monitoring network—essential insurance for protecting high-performance engines from detonation and thermal runaway.
