ok i just made myself a CAI, but i haven't had time to drill the IAT sensor into the intake tube yet. recently, when i'm driving, my engine will feel like it kind of "drops out" and i lose power for a second, even though the gas pedal is pushed down just as hard. also, i used to be able to squeal my tires a little if i floored it from a stop, but now it won't do that. now that the weather is getting a little warmer, i think it may be the cause of the problem. correct me if i'm wrong, but my thinking is that the IAT sensor lets the engine know how much fuel to add. since the weather is getting warmer, the IAT sensor (which is still in the front corner of my engine bay) is reading warm air, while the CAI is pulling in cold air. since the engine thinks warm air is coming in, then not as much fuel gets added. since i'm getting cold air, but less fuel, i'm not getting as much power as i should be. if the IAT sensor was connected to my intake tube though, the engine would read that cold air is coming in, and add more fuel. (if everything i've said is correct, i feel pretty good cause i'll finally be understanding how this all works). well i'm 95% positive that the reason for the lack of power has to do with the IAT sensor, but i just wanted to understand exactly WHY it happened. please let me know if i'm right, or if i'm dead wrong heh

 

here's a pic of my setup for reference...the bluish clip in the bottom right is the IAT..

 

Its not your IAT i had my IAT thinking it was aways 12 degrees out side all i did was destrow my cat from running too rich just do a nice tune up and you will gain the power back. i used to be able to do a burnout if i floored the car now i cant and im at 220,000 miles i have put on a 100,000 miles on the car.

 

If I were you, I would put the IAT in your CAI. Minimize future problems.

My cut out/loss of power was an overheated coil, and/or ignition module.

I doubt the IAT would cause that.

 

These cold air intakes for V6 keep amusing me with their Home Depot/Lowe's look to them. Does anyone gain any real performance or fuel economy with these? I would think you get cooler air with the stock intake opposed to some of these I see mounted behind the radiator. Afterall the stock airbox is used on the V8's as well. Save yourself a cat put back on the stock box.

 

yeah they're worth it...when the air temp outside was still cold, i could feel a slight diff. over stock....mine is actually below the radiator a little....after 5 1/2 hours of driving, the CAI tubing was still cool to the touch...cant beat that

 

I felt my stock airbox after driving the other day and it was cool. The duct to the throttle body may not have been cool but the box was. Besides does anyone have any numbers to prove the increased power or fuel economy? That cold air intake is so unattractive under the hood. For me personally I think whatever gains you are getting do not outweigh the ugly look it adds to under the hood.

 

Sounds kinda risky. Homemade cold-air intake can pull up water during floods, considering how low the camaro is in the first place. On the other hand, LT1 camaros have similar intakes. I noticed that my engine became livelier after adding a pair of K&N intake to my stock MPFI intake.

I don't have any numbers but you can feel a small difference with an aftermarket filter. Not much, but it's something. Plus aftermarket filters make a cool sound. As far as getting wet...the only way it could get wet is if you were tailing a car in the rain. as long as no water is spraying up under the car (which it won't unless a car in front of you is kicking it up) it'll stay dry. i've been VERY happy with my $49 investment

 

Mine used to have the home depot look too. I got an aluminum piece and silicon connectors to take the "homedepot" look out of it. If I had a Camaro I wouldn't even do a CAI. I always thought they had the better setup. Stock Airbox in my Bird was horrible compared to my own CAI, well compared to my current one.


My IAT sensor is right next to my air filter. I don't think I ever noticed a difference from the location of it.

 

I am not trying to make fun, I know how useful a CAI can be. I just wish someone could fabricate and produce something that looked stock and was clean looking. I know for the V8's SLP makes a cold air intake. The only problem with their intake is you have to relocate the battery to the back of the car or elsewhere. I called up SLP and asked about it and he kinda laughed saying I didn't need that much airflow into a V6 anyways. Their CAI is a little pricy though compared to these homemade systems. It would be interesting for someone to have a reader to see what he temperature difference is at the IAT on these homemade systems versus stock. My brother has a 99 Z28 and has a thing called an LS1 Scanmaster and he can tell what that IAT is reading all the time, too bad I don't know of anything that does that for our cars, maybe AutoXray?

 

Weird to hear that SLP wouldn't want to sell their stuff.

 

I didn't mind especially when I found all the trouble I would have to go through to put it in and the expense for whatever little improvement it would add.

 

You are right about Co$t & performance gain.
Ya make your own or get the GM designed stuff for our V-6.
That's all that is needed & yes CAI does return a healthy performance gain when done right.

 

To see if its the iat sensor giving you probelems, do a search for a GM temp sensor resistance table. Then find a resister that matches aproximatly with how cold it is and stuff that in the conector.

clear the codes, because if you don't have the sensor attached the computer proly went into defualt mode and it might not catch the the values. if there's a change go to the dealership and get one for $15(can) like i did.

maybe check the codes first.

 

This is out of my GM 1988 Camaro Service manual for the 2.8L V6:

For reference 185 Ohms is 210 degrees, 450 Ohms is 160 degrees, 1800 Ohms is 100 degrees, 3400 Ohms is 70 degrees, 13,500 Ohms is 20 Degrees. That is if you are going to test the resistance in the circuit. Hope that helps.

 

Were IATs the same for a Firebird/Camaro application (I believe so)?
Were the IAT's same for V-8/V-6 FI versions (I believe so)?

Seeking confirmation or new answers.

 

A home depot intake definitely makes power over stock, no matter what people want to say about it. BUT, HOW much power you make over it is dependent on how you set it up. For example, a short ram will make insane throttle response improvements until the engine warms up, then it's all sluggish. Behind-grille systems pick up way cold air, but the tubing is too long and twisting, so throttle response takes a major nosedive.

My Mustang, I paid $40 total..$20 in filter, $20 in home depot stuff...and made a custom, VERY free flowing TRUE CAI (Sits near the bottom, INSIDE of the fender)...I couldn't relocate it a tad higher due to the parts combination in getting all the pieces to fit together. Everyone's idea of a 3 in. tube/coupling is different. My 3 inch system uses a combination of 3 and 4 inch pipe/tubing/couplings. I've got sheet metal and will make a water shield soon...just gotta grab the tin snips and get off my lazy ****. And for the strip, a separate, screw-up air diverter as well.

 

I have such a problem with "easy to do" things... they're so easy to do, I keep putting 'em off.

A lonnnng time ago, GlennL98 (the prom guy!) had a ton of useful information on the IAT/MAT... let me dig it up.

Found it! https://www.thirdgen.org/techbb2/sho...threadid=60671 I added a post to the end so it wouldn't get deleted due to age. So please don't add posts on to the end of it unless they deal with that topic; the message really isn't about an AFPR anymore.

Thx!
