The EGT probe is a sensor that allows users to monitor critical Exhaust Gas Temperatures to ensure added power is not creating excessive heat which, in turn, can cause engine damage. With the EAS system a user can connect multiple EGT sensors to monitor temperatures in different locations and compare readings to be even more precise.

The Edge Accessory System (EAS) was created with future expandability in mind. The architecture of the EAS allows users to connect multiple accessories, daisy-chain style, to the CS and CTS platform. The ability to daisy-chain multiple accessories using the EAS allows users to monitor and display dozens of parameters on a single device.

*EAS Starter Kits are only available to work with the CS and CTS product lines. In order to use the EAS accessories you must have an EAS Starter kit (part # 98602). EAS Starter kits come with all Juice w/ Attitude CS and CTS products and the EAS Starter Kit w/ Expandable EGT (part # 98603).

I have an edge cts in my 2005 Cummins. My current egts are reading in the low double digits to low 100’s. Sometimes it will read normally. Will this replacement probe fix my issues or should I try something else first?

Asked by: Behemoth421
Most likely replacing the probe will fix the issue. I would recommend giving us a call 888-360-3343 with the info off the unit so we can recommend the correct replacement EGT probe.

Do you need starter kit to install this with insight cts 2

Asked by: Guss
Yes you would need the starter cable as well. If you don't already have it we sell a kit that would come with the egt and starter cable the part number is 98620.

What is the length of the probe that would extend inside once threaded in? Need to know if this would fit inside 2.5" exhaust pipe.

Asked by: Grib

How long is the EGT probe wire, can it be ran past the manifold to the exhaust bung ?
