The heater grid reduces starting effort in ambient temperatures below 59° F.
How does a diesel intake heater work?
It’s just a big resistor that heats up when current is applied across it and thus heats the incoming air charge until cylinder and engine temps get up to operating temperature.
What is an intake air heater?
Air Intake Heaters, also known as grid and manifold heaters, provide solutions for diesel applications such as On-Highway, Off-Road and Power Generation. Powered by the vehicle battery, air intake heaters provide an on-board, stand-alone cold weather starting aid without driver intervention.
