As far as the intake grid heaters go, most new large international diesels have them. Freightliner too. Probably a few other large commercial vehicle diesel engines.
Always leaning Haven't seen one in a while here!

The glow plug name is because someone had the idea to use the glow-plugs (same as used on the engine head) to heat up the coolant. More expensive models typically use a PTC element on the heater matrix, electrically operated, which helps to warm up the cabin while the coolant is cold:

And here is the glowplug version (check the first images)

These can be retrofitted into other vehicles or as a inline heater for the WVO folks.

basically it heats up the coolant (and creates additional engine load via the alternator) as it passes trough.
