Hi, this is my design and product being made. They are made to allow running coolant. through water heated inlet manifold permanently, whilst still having control over on/off on heater etc. I had not seen video before. One of many Australian products of mine over the years, and there are now more ignition products etc under way. Cheers Lindsay Siebler peakignition.
