97RS

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.

archemedes

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

archemedes

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

97z2801ss

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

archemedes

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.

archemedes

it was your imagination

meissen

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.

meissen

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.

archemedes

I meant location in a custom tube
