stock air box mod?

boxcarfan · Post by **boxcarfan** » Mon Nov 26, 2007 1:30 pm

anyone every think of just poping the top off the stock air box? and relocate the IAT sensor? or zip tie it lol? or has someone tried this and something went wrong?......ive got the stock K&N type filter and i was cleaning it up and i had the top off and a started up the car and reved it up....it sounds so mean lol and its better air flow...but anywho....can it be done?

sure it can be done. it's still filtering the air, and sounds pretty good. iat's might go up a couple degrees, not enough to hurt you.

no benefit from keeping the lid off.

you will be sucking in more hot air. its really just for sound in the end.

ha word

the same goes for most intake systems until you go turbo tho, and even then they're still more for sound/looks/space. a CAI is a joke, as far as intake temps go on our cars. but some of them sound good.

Best thing you can do is add a K&N to the stock box and remove the resanator from the fender well. That way you'll still pull in cold air from the fender well but not have the restriction of the resanator. You could even cobble together somekind of dryer hose to route air from your front grill to the IAT sensor tube(the one that went into the resanator) that'd be a true Ram Air set up, can't get much better then that and you don't have to deal with soggy air filters like the CAI's that put the filter in the fender.

ive been wanting to build a streetable ram air for a while but haven't had the time. i already did one for the track.

one day ill do it.

Seems like with the stock air box where it is in relation to the grill it'd be easy to build a ram air system of somekind and still have the filter protected safe and sound in the air box under the hood.

well i already have that big ass box from the fender out...its been out like the week i got the car lol....and when you take the lid off the air box in under the hood that little 90 degree piece comes off...so i pulled the IAT sensor out and pulled it up as far as it could go and zip tied it near the front of the car.....so that pretty much does it and i get that mean ass sound lol.

i had made a ram air system out of pvc pipes. i kept the stock air box and removed the resonator. i placed a piece of pvc pipe with an 90 degree elbow and placed another piece of pipe right behind the left fog light hole on the bumper. it definetly pulled harder and gave me a longer squel of the tires going from 1st gear to 2nd. my only downfall was that if i lowered my car too much, the tire would rub up on the pipe so i ended up removing the whole thing.

so this is why my car periodically throw the 0112 IAT sensor code (?)

put on a short ram intake and filter, but I didn't throw the code for about 6 months after I installed it...and the weird thing is, I installed it in the Spring, and it went thru all the hot Summer months without a problem...Fall comes, like Sept, and then it decides to pop up..WTF?

..and why does it come up like "IAT low voltage"...shouldn't it say something like "high temp"?

Post by **racer12306** » Mon Nov 26, 2007 7:11 pm

sensors don't actually read temp, they read voltage

boxcarfan · Post by **boxcarfan** » Mon Nov 26, 2007 7:59 pm

yea voltage is temp. for a computer

Wenuden · Post by **Wenuden** » Mon Nov 26, 2007 8:12 pm

correct me if i'm wrong, but a sensor code is going to mean the sensor is bad, not that it's necessarily reading a dangerous condition, right? for a dangerous condition, you would get a code specifically for that, right? best example i can think of is an o2 sensor... if the sensor is bad, you'll get a sensor code, if it's reading super lean you'll get a lean code?

boxcarfan · Post by **boxcarfan** » Mon Nov 26, 2007 8:34 pm

low voltage...could be resistance in the wires...could be the sensor...could be resistance in the plug....could be the computer(not likely)...and most likely is the sensor.... basic ele. knowledge

Pablodragon · Post by **Pablodragon** » Tue Nov 27, 2007 6:47 pm

ok..thanx... I think... here are the IAT codes...

P0111 Intake Air Temperature Circuit Range/Performance
Problem
P0112 Intake Air Temperature Circuit Low Input
P0113 Intake Air Temperature Circuit High Input
P0114 Intake Air Temperature Circuit Intermittent

so which one means "replace the sensor"?

lol... i read this and thought about it for 20 seconds... then i figured i can't have all the fun. you go for it. that'll be quite the pain to design. i'm all designed out for the time being... once it's made though it'll be easy to make again and again

Removing the lid still provides good pressure relieve... it's not all about "flow" or temperature.

Post by **racer12306** » Tue Nov 27, 2007 10:20 pm

wouldn't you want positive pressure in the air box, that would be ideal of course.

lol EJ, it's cool. You might get to it before me. I wouldn't be looking to sell these things. Been there done that, and it didn't work. The stuff that I design seem to be only interesting to me. I do stuff for myself now. If people oo and aahh about it, thats just a bonus. But if it works and I like it, then I'm happy.

I modded my airbox and it does get positive pressure using my portable wind tunnel (leaf blower). I did the PVO hood mod plus blocked the back of the turbo ducts off so that all the air is redirected the air box duct. It works because it leaves a dust ring on the K&N filter where the hood meets the air box lid. After doing the mod though it did pick up 1 MPG. It's not a T/A or AAR scoop but it does work.

I used some adapters/couplers that I got form Lowe's and used metal dryer hose from my 90 and adapters down to the scoop in the driver's side fog light hole. You can see it if you check my "Garage" pics. It's really not all that hard to do if you just use a little imagination and hit the plumbing suppy at the local hardware store, LOL.
