How Do They Work?
Our dual coil design allows for a faster heat up and stabilized temperature. Watch the video below and see the proof for yourself.
As can be seen in this graph, the DieselRx® glow plug peaks approximately 40°F higher during the initial in rush of current. The lower stabilized temperature translates to a longer lasting glow plug.
The competitor's plug requires 8 amperes more in the initial rush and 2 amperes more at the steady state of operation. The higher efficiency of the DieselRx® glow plug is attributed to our innovative manufacturing process and quality standards.
