AIH can somebody tell me what this does and can it be replaced or removed to increase airflow i heard 20% more air flow with out it

i can tell you that you are not going to get that much more airflow... but yes it can be removed. there are plugs you can buy to go in its place or what i did, and others have done, was get a reducer and hooked up my boost pressure gauge to that.

The AIH is the air intake heater, it heats up the air when you first start up the truck to help it heat up faster. that is it.

its the single wire stud in the turbo y pipe, get a plug 22mm and remove the element, and plug it off.

Does it throw the SES light when its MIA?

Hmm...That is a pretty good idea. Why didn't I think of that. Is there a benefit to removing it if you aren't going for BIG power? Also, you wouldn't happen to know what size fittings/reducers I would need to use that hole for my boost gauge?
Thanks.

you need to disconnect the wire that is attached to it, mine doesn't throw any codes. i think there is a write up somewhere that states how to do it.

no active codes will be thrown. its good to delete it incase it would come apart, it would go straight to the turbo. its a 22mm port oring plug. dieselsite has the plug to go to a boost fitting.

[cowboyupamrka]

it is stated as a 22mm. then you just have to see what you can find to get down small enough. i think i used a large brass fitting, i would have to go look, guessing 1/2 NPT but can't remember. seemed to tighten up okay without any issues, but never really checked to make sure it doesn't leak. there might be something outthere that someone makes now that is the correct sized reducer. i would guess the only advantage is you get a little better flow characteristics, but nothing major.

[cowboyupamrka]

technically it would go into the engine... not the turbo... i have never really heard any horror stories myself of this happeneing but there could be some.

your right. i did use 1/2 npt in mine and just put two orings on it, and some pipe dope. been on there a year so far.
