Introducing the Holley EFI 8 Channel CANBus EGT Kit. Exhaust Gas Temperature data is critical information when your engine tune up is on the ragged edge. Knowing the exhaust temperature of each cylinder can help you identify potential horsepower left on the table, or pin point any weak links in your max effort race engine. You can also use this data to quickly identify a potential ignition misfire, or stuck injector! The included sensors are designed to work with any engine combination, with an open reinforced tip for the fastest response rate, and improved shielding. The probes come in 4 different lengths ensuring a clean looking installation. The included 316 stainless steel bungs feature a built in step, making bung installation as easy as possible. Everything needed to upgrade your exhaust system is included, such as 1/4 in. 316 Stainless Steel EGT Bungs, 8 EGT Sensors, and the 8 Channel CANbus EGT controller!
