Basically, in the intake, there is an element in there like a glow plug that heats the air coming into the engine, so it starts with "warmer" air.
Some trucks, this is all they have to start on, no glow plugs, only AIH.
Like the old cummins, they have AIH, and can start in the cold just the same as us.

Cummins are also a mechanical engine with way different cylinder carachteristics. they have 60 CI per hole we only have 55. that itself means colder temps while cranking.
AIH's are a joke. Bobcats had them back before they went to the scissor style lift and they never did squat. dont waste your time trying to build one.

I just had the intake off on a 24v. The intake heater consists of about 6-8 bars that are 1/2 inch deep. Pretty basic setup.

I have seen Perkins engines on boats that had a air heater in the intake that burned diesel. They had a nozzle like an oil furnace and an igniter. When you cranked the engine it would turn on and light the fuel right in the intake.

the aih on superduties are a waste. all they really do is clear up a little smoke at startup on really cold days. alot of superduty guys take them out because they restrict airflow into the engine. they take the aih out and thread their boost guage into the hole where it was
the stage 1's and chip from rosewood are exactly what i want. how do you like em?
