5s-fe? It's just an airflow sensor. NOT a MAF sensor. It's not really needed.

I have never understood people that just reply with "search". If you aren't going to answer him, why even bother replying on the thread? I remember my first time going on to forums, I had NO IDEA how to search for info. I would go on and ask questions that have been asked a million times before and you know what? I STILL might do it. There are times that I have actually searched what I was looking for, couldn't find it, but it was there the whole time.

I agree with the OP, cut him some slack. If you aren't going to answer his question or can't give him the info he wants, don't bother replying. Forums are for sharing info with one another right? The last time I checked, that is what forums were for right?

:thumbsup:

I was thinking it looked like it may be a temp sensor. but wouldn't that effect my air/fuel mixture? I assume I could drill a hole and plug it into my aftermarket intake. but id rather elimanate it entirely. I like the look of minimal equipment and wires under the hood.

Pretty sure that's temp control. What you COULD do (which would benefit you further) is relocate that to somewhere cooler...like maybe where you stick your filter! I don't know if that's been done before but that just crossed my mind.

I'll try it out and post my live feed results when I do (though I have to get the transmission put back first...)

I always assumed it was the IAT sensor, but I've never had to know, since they just don't ever go bad. Just drill a hole in the new intake and stick the grommet in it. There should be enough room to hide it on the bottom side of the pipe, or you could add some wire and stick it behind the fender.

Isn't it an intake air temp sensor?



How so?
Air TEMPERATURE sensor, yes, I'm sorry. My fault on that one. :facepalm: You don't really need it to be connected to the intake apparently because the temperature in the box is similar to the ambient air around the box. If you REALLY want to... do what I did:

Yes.

I don't know what type of intake you are installing but the stock is already a CAI. If the new intake has one of those filter cones that just sits in the engine bay then you won't have a CAI, just a cool looking, air hissing, filter. If you don't tell the ECU what the air intake air temp is it won't give you the correct mixture, or if you install the temp sensor in the hot engine bay then you will get less fuel and less power.

but id rather elimanate it entirely. I like the look of minimal equipment and wires under the hood.
Why? What's your purpose in putting in the aftermarket intake? It's clear you didn't do much knowledgable research before doing this, now you want to really screw it up.

dude, this is my research. I have not purchased anything yet. as far as I know asking questions will not "really screw it up"

haha nice. It's true the stock intake is cold air only. Instead of buying a new intake, you could get away with a free modification like I did. I left the original box and piping, but there are 2 resonators on the intake. One between the intake manifold and the airbox in the piping, and one in the fender. If you remove both of those it will flow a little better and sound a little more aggressive. I took mine off, and to seal the hole in the piping I took a rubber bike tire inner tube, cut a square out of it, and placed it over the hole then tightened the stock clamp back down onto it. Popped inner tube + a few minutes of time= about 3 cents. It does the same basic thing an aftermarket setup does, but it just isnt chrome and flashy.

You really only gain from a cold air intake if you have a stock intake with a hot air inlet from the exhaust manifold or a really restrictive stock setup.

I used to work with older chevys with a sbc 350 engine. the minimalistic look was very common. people would re-locate the battery in the trunk just to clean up the engine compartment. so that same mentality is still stuck in my head. less equipment underhood, and eliminate ugly plastic for polished alum. parts.

mmm, interesting. may go this route and run a k&n filter. will this help fuel economy at all?

Hardly a change in fuel economy. Getting an aftermarket intake on a 5s-fe pretty much only gives you a more agressive sound and a slightly noticeable improvement in response on lower rpms.
At least from my experience that is.
