See above and the only con I know of is that you might smoke a little more when it's cold out.

Better airflow...it protrudes into your intake and takes up about 20% of the space there, you don't really need it, it is easy to do (took me 5 minutes), you can by a plug that screws right in from many of the sponsors on this site. I bought a regular plug ($9 shipped I believe) from blackclouddiesel...then when I installed my gauges I bought another one from them that had a built-in boost gauge tap where I tapped for my gauge. It screwed right in also. Piece of cake mod. Better airflow can mean better efficiency/fuel mileage even though it may be very slight with this mod it was worth it to me /ubbthreads/images/graemlins/smokin.gif Cons..??????? /ubbthreads/images/graemlins/confused.gif /ubbthreads/images/graemlins/confused.gif...your hands might get dirty /ubbthreads/images/graemlins/shrug.gif
The mod allows air to flow through the intercooler more freely. I noticed some improvement in throttle response. Two down sides, if you let your truck idle in the cold weather for long periods of time this mod might be isses. If not don't worry about. Second, when you disconnect the AIH from the seleniod your truck's computer might through a code. Not all trucks do this, but mine does. It's not a big deal, the code doesn't effect the truck.

We've actually developed a code eliminator for those using the AIH plugs.

Black Cloud, you guys are bring to modest. That plug/boost gauge fitting for the AIH delete is a really sweet mod that works very well.
I guess your code eliminator works too, cause my truck has never thrown the code /ubbthreads/images/graemlins/cool.gif

For those that would like to make their own AIH plug with a boost fitting, here is how I did it.
Parts needed (less than $5 total):
Parts
22 x 1.5 metric plug (fastener shop, about $2.50)
1/8 close nipple (Lowes $.90)
1/8 female pipe coupling (Lowes $1.30)
1/8 fitting that came with your boost gauge (priceless)
Drill and tap the plug for the 1/8" nipple, assemble and install. That easy.

PS: I removed my AIH, not so much because it was a restriction, but because I needed a handy place to plumb my boost gauge into after installing a relief valve in my MAP line. But, after looking at it, I'm glad it's out.
I just used a 10w 470ohm resister as a code eliminater (electrically replaced the heater element). Since I don't have a code reader, have no idea if it worked, but didn't hurt.
ForumBlue,
Before we let opinions and speculation get in the way of the facts I just measured as best I could the actual SOLID obstruction area of the IAH that I removed and compared that area to a 2, 2.5 & 3 in circular air intake track (not sure what dia the intake track is where this is installed) and below are the FACTS unless I made a math error ...
Solid diameter and length of the IAH - 5/8" x 2" solid obstruction ~ 1.25 sq in
2in dia air intake ~ 3.14sq in
2.5in dia air intake ~ 4.91sq in
3in dia air intake ~ 7.1sq in
% restriction in
2 in intake track = (1.25x100)/3.14 ~ 40%
2.5 in intake track = (1.25x100)/4.91 ~ 25%
3 in intake track - (1.25x100)/7.1 ~ 17.6%
If you don't think those % blockages are significant not sure why everyone is trying to get more air volume with bigger turbos, larger intakes, intake plenums, etc. running hundreds to thousands of dollars when a under $10 mod will reduce you air intake area restriction by at least 10% which IMO is not insignificant.
I think Bob Riley's assessement of the blockage as <font color="red"> HERE</font> of almost 20% is why he was the first vendor to offer this mod IIRC.
FWIW ... By comparison while it's on the exhaust side many folks remove the EBPV "flapper" to open up the exhaust due to a restriction and again I don't know the exact dia of the fitting where that "flapper" is but I've looked at mine and it looks to be around 1/8" wide and below are the % restrictions that represents for exhaust diameters from 2 to 4 in.
% restriction in
2 in system (100 x 1/8in x 2in) / 3.14 sq in ~ 8%
3 in system (100 x 1/8in x 3in) / 7.1 sq in ~ 5.3%
3.5 in system (100 x 1/8 x 3.5) / 9.62 sq in ~ 4.5%
4 in system (100 x 1/8in x 4in) / 12.59 sq in ~ 4%

Did you honestly feel a difference or pickup a detectable amount of fuel mileage?

No data and doubt I can produce it since I've driven the Van like 5 miles since doing this. I don't believe or pay any attention to most of these seat of the pants evaluations because of the placebo effect. I also don't evaluate things on much of a short term effect and have done things in the last year that have thrown my previous baseline all to heck such as the BTS, the 3.5 to 4 in exhaust, the areoturbine, 203* T-stat and now the AIH each which might have some effect. My baselines take several years under exactly the same repeatable conditions and routes and the biggest effect that I have seen is what direction E to W or W to E I have been traveling. However, I haven't confirmed it yet but with all the mods mentioned above I seem to have picked up around 1 mpg towing, but I need another year or so to confirm that. Also, I wouldn't even have a WAG or SWAG until this Aug when I start towing again and hopefully I'll have another variable (a Jody Tipton PCM) so it's a new ball game so to speak this year.
Also, don't forget what we're talking about here are folks that aren't trying to "force fit" 10 lbs in a 1 lb sock like "Snow White", but have mildy or stock trucks just wanting a little better performance.
Also, for us as you as a vendor and me discussing a competitors product such as this AIH delete mod unless you also offer this mod thru DI which I could not find is not IMO appropriate since the TDS rules clearly state that ...
Vendors are not allowed to discuss their competitor's products in any way shape or form. Vendors are far from impartial and we don't feel it is ethical to allow them to evaluate their competition.
If you feel we need to discuss this further maybe a PM or e-mail and not this venue would be more appropriate.

Does anyone know if a carburator shop or head machine shop could flow an intake (out of the truck) with and without the AIH in and tell if there is a difference in the amount of air that it blocks? I have an extra intake, an extra AIH and a plug. I am now very curious what the real differences would be under normal boost (3-5lbs) and full throttle boost (17-20lbs) on a stock truck. I'm starting to think this mod is just a gimmick to sell a $2.00 plug.
Someone please correct me if I'm wrong. Isn't 15lbs of boost 15lbs of boost whether it's in a 4sq inch volume tube or a 4.25sq inch volume tube?

15psi is 15psi, but 4.25 square inches will flow 6.25% more than 4 square inches.

Good point Matt but when is bigger too big on a stock truck? Would 6in pipes through out help or hurt a basically stock truck or slightly modified truck? I'm still curious, does anyone know if a head machine shop or carburator shop can flow a stock intake?
