3.8 Intake Electric Thingy
 

Im making a cold air intake for my car (3.8). There is a sensor in the stock cold air intake (referring to the pipe right before the maf) I assume its an air temps sensor or something. Does anybody know what it is, I need to know so I feel better about drilling a hole in my pipe and gluing it in. Regardless it should go in, right?

Prolly the IAT and yes u need it so ure car runs right

all my freind did on his was drilled a hole and used a rubber gromet to fit it in there perfectly

so your getting rid of that tipe that goes from the air box to the maf, and replacing it with a straight pipe? i was thinking about doing that but i was unsure on what kind of results i would get

please, never again call the stock intake ducting the stock cold air intake. it makes you sound like a ricer.

in answer to your question...of course its required! the 3.8 has quite a few little sensors n such in front of the throttle body, but no matter which it is, it is definitely required.

if a wire connects to it under the hood it is needed or a code will set

also putting it in the wrong spot in teh tube can set a code

yea, but with the IAT i herd u can movie it closer to the filter....for colder reading

and you'll dump more gas couple that with a cold t stat and it may set a code especiallly when it's cold and wet

If it's the same as a 3.4L IAT, you can purchase a specific resistor for your make and model and plug it into the wires that go to the computer. It basically makes the car run a little lean. I don't know if it's still on ebay or not, but it was the big "mod" that ebay had hundreds of listings for. I used it on my car and I thought I felt a definite difference (but it could've just been my imagination), and didn't trip any codes either.

it was your imagination

:lolsign: Well it did run leaner. In any case, it'd be an easy fix instead of drilling into your intake.

actually as i found out from tearing my engine down, every sensor has a different plug...or at least, the different groups of plugs are different.

but yeah brian that is your imagination. i've seen that on ebay and tons of idiots like you buy a .50 resistor for 10 bucks plus shipping for absolutely no gain.

Uhm, I actually bought it for $5 shipped and then went to aco, bought a 10 pack that are all the same measurement as what he sent me, and then resold each resistor seperately with a buy it now price of 2 bucks. :lolsign:

I meant location in a custom tube
