If the heat shield thing doesn't work out for you, and if you could find a decent way to plug the hole in the pipe... It'* not that hard to extend the sensor wires to reach the filter. Just make a cut, , bare the ends, and solder in however much wire you need in between. Use some heatshrink tube to cover the soldered joints, maybe some extra wire loom to hide the job... and you can put that sensor anywhere you want it, filter included.

That what we did on mkaake'* LeSabre, and what we'll be doing on mine in about a month.

Other than that, the intake looks good. Can't wait to see the heatshield.

So did what I wrote go over everyones heads or what? Forget it, put your IAT in the AC vents for all I care, I know where mine will be.

sweet attitude

anyway...your IAT needs to be able to read the coldest temps that your air is pulling in...i have mine in my pipe (although it is well insulated) and reads within 1-5 degrees above ambient

I'm impressed with the attitude as well. Try to think of the sheer volume and velocity of the air running through your pipe, and how much heat it can actually transmit to that air. Not much. Now why would you put your IAT near a source of heat or at a hot portion of the intake pipe, instead of at the source of the incoming cold air?



Don't listen to us. We have NFC what we're doing with our cars. And no experience with intakes, either.

The pipe came from autozone, and the couplers as well. The filter came from AJUSA. I noticed better throttle response but not much difference under heavy throttle honestly.

Just to see where Optmus is coming from, the sensor would be reading the warmest section of air which would be the most accurate reading of what the temperature of the air really was that entered the engine. LIke mentioned, if the temperature is read lower than what the air actually entering the engine is, the computer will adjust for it because of knock and air/fuel ratio, correct? I'm not saying the sensor is staying where it is, I"m just trying to see different sides of it. I might move the sensor to the heat shield I build right next to the filter. There is no where else to mount it into my pipe.. The rest of the pipe is almost all covered in rubber from 3 couplers.

Right, that'* what optimus is saying. But it'* not quite true. The pipe will be hotter at that point, due to it'* proximity to the exhaust crossover pipe. The air flows through that hot pipe very fast though, picking up very little heat along the way. Meanwhile, the sensor will likely be getting a false hot reading from the hot pipe, rather than a true reading of the cold air passing through the hot pipe. See what we're saying here? By moving the sensor farther down the pipe or to the enclosure or filter, you're not trying to trick it by giving it a false reading, you're trying to give it an accurate reading, uncompromised by exhaust heat.

When I get to making mine (probably thanksgiving weekend), the sensor will be going on either the filter, or the enclosure.

Ask yourself where the FACTORY put the sensor.

Away from all sources of heat, directly behind the air filter.

EXACTLY what I am saying. Which is why, in the intake I made the IAT is the roughly the same distance from the TB as the orginal one.

Nice to see some brainstorming in this section for once.

The way i did mine is followed the rice pipe theroy. Bought the rice pipe at autozone. And cut it to fit. At first I had my IAT in the same place as Custom, because of the hole in the pipe. I got a K&N RX 4750 from AJUSA. It has the IAT hole in the filter. All you have to do is use a dremel with a drill bit and carve it out just a bit so the sensor fits.

Bought a 18"x24" piece of plexi from Loews and traced the filter on the plexi with a sharpie. And went to cuttin'. I sorda followed Bill'* pattern for the heatshield.

I guess my temps are good, no probs so far.

I like the way it sounds. I'm not SCd so I take what I can get. It does sound like it is inhaling large amounts of air though.
