Haltech 1/4in Open Tip Thermocouple 33in Long (No Fitting Hardware)

This is a 33-inch long, 1/4-inch open tip thermocouple from Haltech. It's designed to measure exhaust gas temperature (EGT) in performance applications. Accurate EGT readings are crucial for tuning engines, especially those running high boost or aggressive timing, as they help prevent detonation and monitor engine health under load.

The open tip design allows for quick response to temperature changes, giving you real-time data to make informed adjustments to your engine's fuel and ignition maps. While this thermocouple itself is well-made, remember that it does not include any fitting hardware, so you'll need to source that separately to properly install it in your exhaust system. This part is not CARB approved and cannot be shipped to California.
