Is this an electric or mechanical gauge and will it fit my 1968 Barracuda  318 engine?  What does AirCore mean?

Asked by: Raymond1947
Thank you for your question. This is an electric gauge. AirCore refers to our short sweep electric meter movement. The sensor is a 1/8" NPT male fitting. If the port on your '68 Barracuda engine is not 1/8" NPT you will need an appropriate adapter.

Thank you so much for contacting us. Unfortunately, all of the temperature sending units used with AutoMeter gauges are 1/8" NPT thread. While we do offer different thread adapters metric adapters, we do not makre one in that size. This is the correct sending unit for this gauge: Hope this helps!
