The Exhaust Gas Temperature Probe that comes with our Pyrometer EGT Gauges is the EGT sensor you install to your car or truck’s exhaust manifold for exhaust gas temp readings.

Our version is a 1/8-27 NPT Type K Thermocouple EGT probe with a waterproof connector and 3’ of stainless steel braided cable attached. It comes with a 6’ stainless steel braided sensor harness that also has a waterproof connector.

Where you install the probe is key to getting the most accurate readouts. There’s different opinions about installation, with some people saying to go before the turbo and others saying to go after.

We’re in the first camp. Our Tech Team recommends going pre-turbo to get the most accurate readings from your EGT sensor. This way you’ll know exactly where your exhaust gas temperature is at any given time with quick, responsive readouts.

You want to make sure you know what the temperature is going into the turbo to make sure it isn’t running too hot. The harder you’re pushing your application, the higher the exhaust gas temp will be which can lead to temperature spikes. The end result could be damage to your turbo in the process.

Find a flat portion on the exhaust manifold where all the cylinders flow into one before the turbo. Next drill and tap to 1/8-27 NPT, thread in the EGT sensor, run the included sensor harness to the EGT gauge and you’re ready to go.

We also have EGT Probe Adapters like Thread Adapters and EGT Brackets that save you time and effort during installation. So when you’re looking for the best EGT probe to make sure you’re getting the most reliable exhaust gas temperature readings, find out more about the EGT sensor that comes with our EGT pyrometer gauges.
