AIH Delete?
 

What is the purpose of the AIH delete, what does it gain you, what are the pros and cons?

Nothing in any context of your questioning.

??? Why are people doing it?

Makes the truck lighter.... Delete enough stuff and you become faster... 100lbs is a tenth...

:D

Wait, what, I must be confused, I thought the AIH was the air intake heater.

It is.

There's no reason to delete it. You won't feel, hear, or smell any kind of difference in the way the truck runs.

Personally, I feel that most folks claim to have done the "AIH mod" just to inflate their forum signature.

:D

While I agree with you... There is also no reason NOT to delete it. It does nothing, blocks airflow thru the Y pipe and just adds a mess of more wires.

Delete and be done.

What kind of temps do I need to see before it would be usefull?

Extended idling below 40 degrees ambient.

Still not that useful. It's an emissions device. The last time an emissions device was actually good for anything was in the mid-60's when PCV was introduced. The dyno says that the same power is made whether or not it's there.

It has nothing to do with cold starts. It does not even come on until the oil temps REACH a certain point (I believe 120* or more but I cant recall)...

Parking brake has to be set and voltage has to be above 12v...

Its completely worthless and was added only to help stop white smoke issues when people would leave there trucks running for hours at a time.

Operating conditions:

Engine at idle.

Ambient temperature below 32 degrees.

Oil temperature below 130 degrees.

Battery voltage of 11.8-15 volts.

Will activate for UP TO 30 minutes ONCE per key-on cycle. Will not reactivate on same key cycle after any of the above conditions are no longer present.

I need to customize it, my truck will idle all day in conditions well well into the negatives. Wind chill of -50.

how do u delete it? just unplug and romove it? lol sorry kinda a dumb question. :w2:

No, what you need is a AIC (Automatic Idle Control) or a high idle setting on a chip. The Intake Air Heater will do nothing to prevent wet stacking, only help with visable white smoke during extended idle times.

If your leaving your truck running in conditions like that you need to keep the EGT's above 300-350*...

You should have a factory cold weather package that will close the EBPV (Exhaust Back Pressure Valve) and idle the truck up to about 1150RPM.

You say factory, is there no way to mod my exsisting?
