This write-up is at the end of a long learning curve as I searched for the best thermocouple for my application. All will work just fine on our trucks, but there are some small differences. I, like most of you, just assumed what the vendor sent was what was suppose to be the "one". Well, we do have some choices. For those of you planning on installing an EGT gauge, you might want to read this first. Be informed, and ask for the particular thermocouple that best fits your needs. This may be too much info for some, and doesn't really make a difference, I've been told, but for those of us that are anal about our truck, installing the mod best suited for us the first time around feels good.
We've all read the long threads about drilling, tapping and the dreaded steel shavings. This issue is also addressed.
Here are some pics of some of the various types of ISSPRO Thermocouples available for our PSDs. These are of the drill and tap variety. All are adjustable in length. (How far the tip sticks into the pipe).
Please pay close attention to the length of the probe and the diameter of the threaded plug. Also, notice the connection of the thermocouple wires to the lead wire.
