The Holley EFI Single Channel EGT Kit gives racers a direct read on exhaust gas temperature, helping spot horsepower left on the table, weak links in a max-effort engine, or an early warning of a misfire or stuck injector. This analog version pairs the sensor and bung with an unterminated-output controller for use on non-Holley EFI installations.
Specifications:
- Controller: Single Channel Analog EGT Controller, unterminated output wires (for non-Holley EFI installations)
- Probe: 1/4" open-tip EGT probe, 60" lead, pre-terminated connector
- Bung: 1/4" 316 stainless steel weld bung with built-in step for easy welding
- Application: Universal, bolt-on
- Part Number: 554-184A
For a plug-and-play version that connects directly to a Holley EFI CANbus system, see the 554-184C kit instead.
FAQ
Is this kit compatible with a Holley EFI ECU?
This analog version (554-184A) has unterminated output wires meant for non-Holley EFI installations. For direct Holley EFI CANbus compatibility, the 554-184C kit uses a CAN module instead.
How long is the probe lead?
The included probe has a 60" lead with a pre-terminated connector, giving flexibility for mounting in most locations.
What does the kit include?
The kit includes a 1/4" 316 stainless steel EGT weld bung, one EGT probe, and the Single Channel Analog EGT Controller.
Does the bung require welding?
Yes. The stainless steel bung has a built-in step that holds it in place during the welding process for a clean weld.
