1/2 NPT Temperature Sensor for Holley Sniper, 1/2 Version of Holley 543-120

1/2 Inch NPT Coolant Temperature Sensor — Holley Sniper EFI Compatible
(1/2" version of Holley 543-120)

Ships from Pennsylvania, USA!

Holley doesn't offer a 1/2" NPT temp sensor compatible with their Sniper EFI systems, despite many stock and aftermarket intake manifolds only having 1/2" NPT ports. Using an adapter bushing puts the sensor out of the coolant flow and almost guarantees a small air pocket around it, resulting in skewed temperature readings.

I ran into this issue myself and found that nobody makes the correct sensor for this application; so I made one. I've run and tested this sensor on my own vehicle for 3 months. Simply drop right in, and go!

1-Day Handling, 90-Day Warranty

NOT compatible with Holley Terminator — Sniper EFI systems only.
