Intacke heater question
How big are they?
How hot can they get?
Can they run as long as a glow plug.

Burn a diesel up by leaving them plugged in? explain more
That is why it's a good idea to have a timer, or only plug it in before starting.
Most block heater cords don't have very thick insulation.
I'm not sure how much that small heater can do by itself since it's designed to work with the glow plug system.
If you want to preheat the engine before starting, look into a diesel fired preheater.

Here's a link to the ones we use in some of our equipment. The D10, is a 10kW unit and is used in a 8L engine. Heats the engine and the cab up very nicely.
(The 4.5 liter V6 is different, on that model the two systems do work together...)
To the OP's question....
The Air Intake Heater is not effective enough to start these trucks in cold weather. You would need a heating grid like the Cummins engines have. Those grids would need to be as close to the intake valves as possible so you would need one for each side. Now that billet intake plenums are available, it wouldn't take too much additional effort to fit a grid heater on each bank.
I prefer the grid heater vs glow plug system myself....they seem to work much better in my region. However, the glow plug system works well enough on our 7.3 trucks that we leave them alone. (Why change something that works?)
Our 4.5 liter trucks do NOT like starting up when cold. The glow plug/AIH system is not working for us so we have to leave those trucks plugged in with block heaters. We put them on a timer and we jacketed the block heater cord. If the cord shorts out, then it will blow a fuse on the timer and shut off the power.

I was looking at hook the heater up with the glow plugs to help with starting, my old truck is a little short on compression when it's cold
