Engineered for both diesel and gasoline engines. At -30℃, it rapidly heats the coolant, increasing its temperature by 15℃ within 5 minutes—effectively reducing oil viscosity and start-up resistance caused by low temperatures. Minimizes engine wear during cold starts, especially suitable for Duramax diesel-powered vehicles in winter.

We have increased the cable length from 59 inches to 98 inches and optimized the connector design for greater stability during use.
