What is the purpose of removing the AIH any performance gains that you can notice. Also the foil delete....I have read about people removing the foil is it just for sound purposes that you can hear the turbo more. I guess the purpose of it to begin with is it heat related??
No gains from either, while I guess it could be said that removing the restriction from the spider (AIH) could only help the engine breath, it's certainly NOT something you would ever notice. The Foil Delete does nothing more than un-do the noise reduction the foil insulation gave.
when you remove it and install plug , you get a stink of unburned fuel coming out exaust when you fire it up cold your neighbors will hate you , slower warm up
I removed mine and yeah it seemed like it made some more power , but I can tell now its harder to start and seems like it takes longer to warm up , it stinks bad sense its colder when im warming up , thats all i can say , I might plug it into harness to see what its doing if its coming on at this temp 40s I hurd its supposed to be 32 or lower and all this other stuff but i will check it out

Nonsense, the AIH has absolutely nothing to do with starting cold or otherwise. And, I assure you, you could never "feel" such a miniscule performance increase IF there even was one.
One of the many criteria needed to turn-on that heater is that the Glow Plugs be OFF at the time. This means your engine has already been running for a couple of mins in the cold weather.
What not for cold weather ? wow thats a New one whats it for then ? what would a (intake Air heater starting Aid System) be for then ? The starting AID system is ACTIVATED below 32 F degres outside air when the oil is Below 131 f The intake air HEATER will stay on For up to 30 min while Idling Per FORD shop Manual
NOW WHat WERE YOU SAYING :Nonsense, the AIH has absolutely nothing to do with starting cold or otherwise
:doh: Look, kid, sometimes you gotta think for yourself in life.... :wink[3]:
How could a "Starting Aid" possibly work that is blocked from activating until the GPs have cycled completely Off? Come On, think about it!
These are the parameters that need to be met before it will activate. It will not come on unless All of these are met.
• ambient temperature must be below 0 deg C (32 deg F)
• engine oil temperature must be below 55 deg C (131 deg F)
• vehicle power must be between 11.8 and 15 volts
• parking brake must be applied on manual transmission vehicles
• the transmission must be on park or neutral on automatic transmission vehicles
• glow plugs must be off
Some AID huh? It can only help you start the engine until it's been running for a couple mins. (you DID read that in my previous post -right? and yet, you chose to go on with this) :haha:
Here's what it's all about, during periods of extended idle times (like with Ambulances & Emergency Vehicles) you can have, what's called wet stacking (look it up...) and the production of vapors. So, to help with preventing that, the designers decided to add the AIH as an Emissions issue (and I don't mean to :bdh: here) NOT STARTING!!!
No were in my FORD shop manual Does it say the Glow Plugs must be off as a criteria ! YOU stated it has nothing to do with ( cold weather or starting)
• ambient temperature must be below 0 deg C (32 deg F)
• engine oil temperature must be below 55 deg C (131 deg F)
• vehicle power must be between 11.8 and 15 volts
• parking brake must be applied on manual transmission vehicles
• the transmission must be on park or neutral on automatic transmission vehicles
• glow plugs must be off ((((( FALSE ))))
Also FORD never made a ambulance they were all aftermarket conversion nothing was designed around a ambulance by FORD
when FORD calls it a Intake AIR SYSTEM STARTING AID

First, it's contradict, and Second, I'm just as consistent as I Can be! Your source is just wrong, it's a misprint, edit, or you're making it up. BUT in any case, I can't confirm what you're saying anywhere else other than your "flapin' gums" :wink[3]:
Is this your Owners Manual?
Try it! Google Ford 7.3 AIH and see if anybody else has conveniently left out the GP's being OFF part. So far, it's just YOU......
Well, ya know,,, that's Very interesting. Really the first thing I've ever seen like it! If your not being cute here, and taking a different picture of the cover, I have No Idea who's right.... You might have something there, I'm not totally convinced or anything, but you might have something.....
I can't verify the origins of the "common" knowledge that the GPs are involved. But, everywhere I've looked says the Are. Thing is, they may all have come from the guys Selling the AHI delete stuff I wish I knew more, wish I had the time to track it down, I use Ford DVDs, I'll look later... Maybe somebody who has that answer will let us All know.
For now, I gotta give you your "props"...:wink[3]:
(this is the only references I came across in the past 20mins of Googling)
:agree: Since I used to be a diesel mechanic I would say that the AIH (air intake heater) is to warmup the air which causes the fuel to burn,which then helps clean up the white smoke that is unburnt fuel at startup. Go out to a truck stop on a cool morning and look for the oldest truck there when it starts there will be white smoke until it warms up, ford was just trying to eliminate some of that.:doh:
Delete both.
The turbo will whistle more on the hot side CAC tube. No performance gain/loss.
AIH delete is no performance gain/loss. Maybe a touch better air flow. Made me feel better :thumb:
Yeah if your in climate is cold it works> in warmer climate pull it , Its not needed .
the other is I was trying to provide accurate Info for the man , there is alot of BS pushing on all these diesel forums on the web and half of it is BS totaly wrong, Another site thread was telling a guy he had a boost leak and to tear his whole truck apart to find it several people told him to FIND the leak he kept looking and looking for a boost leak ?he was complaining of a loud hissing sound like a compressor (newb) when it started and it was cold
all it was is he just bought it and it had a exaust warm up valve kicking on in the cold and it sounded this way totaly normal but yet every one said you got a boost leak pull it apart poor guy needless to say he never found a boost leak .
I live in northern Minnesota, we have many days below zero per year. My truck does a lot of idling and I'm not always at a location where I can plug it in at night, so a lot of cold starts. I've done the AIH delete and have never noticed any difference in smoke or cold starting. I just started my truck ten minutes ago at 8 deg. F after sitting all night, no white smoke what-so-ever, or stink.
