Modification: Warm Air Intake

<p>Yup, you heard right: <em>warm</em> air intake. So basically, the idea behind this is to reroute your air intake to suck air from somewhere hot, and that hotairness will get picked up by the temperature sensor on the intake and the Engine Control Unit (ecu) will lean out the car's air fuel mixture, meaning you use less gas! Sounds pretty cool, huh? </p><p>The actual modification is pretty simple:</p><p>Take some hoses and duct tape and attach something to the end of the intake and run it down near the catalytic converter where it'll suck some really hot air.</p><p>&nbsp;This would make a great experiment I should think, and it'll be good to do it, but first it would be good to standardize to a degree the materials, tubing size, and placement first, as well as getting it done properly with some pictures posted to do a good DIY on it. </p><p>Whaddya think?<br /><br />

This first picture is of the hoses you need to go buy at your autoparts store. Should be under 10 bucks each, 30 inches per hose.

Tape the hoses together like so to make one big ole hose.

Attach one end of the hose to your airbox and snake it around so that the other end of the hose can get down to your catalytic converter.

Here's a picture of the end of the hose sucking air from near the catalytic converter!

Pretty simple and quick and quick, if I do say so myself.

I have even heard of

I have even heard of plumbing a small heater core to fit in the air box.

I've never heard of that but later on I will post about creating an air damn behind the radiator to keep the engine compartment warmer. ^_^

two weeks later - how is the software?

On one forum I saw a guy who made a WAI/CAI combo.&nbsp; It had a small sensor that read the temperature of the air.&nbsp; When the air reached a certain amount, it would switch between the warm air and cold air.&nbsp; My understanding is that the marginal benefits of WAI decline after the temperature outside is a certain level.&nbsp; This contraption that switches between Warm air and cold air depending on the temperature of the air is a cool idea of you ask me.

I imagine it has something to do with a something something. What are the called. Some sort of valve you stick on your CAI is you don't want to get hydrolocked. I dunno, something electrical, I can;t think how to fab up something like that offhand.&nbsp;

no, I could put the air

no, I could put the air temp sensor over my radiator hose. That way my car thinks its +100F. And it leans out the fuel a bit.

Well, that is what i hear.

Haha

You could do that also, but I figure it would be less bad to not move the sensor all over, but what do I know.

On my Saturn, I just unplug

On my Saturn, I just unplug the air temp sensor and stick some resistors in the end of the plug. On this car it is around 110 ohms or so. This way I can easily return everything to stock when necessary.
