The cost of the Air Temp Sensor is $100 plus shipping from Dan at UFMotorSports.

The labor is on you! ...

OR ...

you'll have to find a M-Technic mechanic that will do it for you.

A BMW dealership will NOT do it.

At least they wouldn't do it for me!! They said that they will have "No Part" in helping me void my new car warranty.

how the hell does that void new car warranty? thats the dumbest thing i've heard, some bmw dealers can be real pricks. well since its DIY install im definately capable of doing it.

$100 doesn't seem like a bad price for well done kit that will help power loss. thanks agian

Hey T,

I believe the Stock sensor is near the drivers side MAF. We are talking about Air Intake Temp Sensor. Not the temp sensor that tells you how hot it is outside and gives you a reading on the dash.

The one in question tells the Engine the temp of air it is getting. When the sensor gets Heat soaked (Hot from the engine) it gives the engine false readings.

If we move the sensor away from the Hot motor, the sensor wont be hot, and therefore can give accurate readings.

You don't warm up a thermometer before you take your own temp do you? Same deal. The stock location starts to read engine temp instead of Air intake temp, thus a falsly high reading.

Hope this mad a little more sense.

oh ok... was thinking the wrong thing...
so if the air intake temp sensor is inside the MAFS, then what about with the Dinan MAFS? The Dinan ones are much more insulated than the stock ones... is it possible to relocate it for that? or is it even necessary at all?

TFung...check out the link I posted to UFMotorsport. Don says that you can't insulate them well enough. I believe the Dinan MAF's also incorporate the air intake temp sensor into one of them, but the new upgrade to the Dinan CAI will move them temp sensor down by the front bumper, near where the outside/ambient temp sensor is.

Believe me, it makes a considerable difference on the hot days!

The Dinan CAI has ANOTHER upgrade?

the last upgrade I did to the CAI added some heat shields near the filter area, and I was told that a temperature sensor was moved... maybe that was it.... wonder if that would be the same as the UFMotorsport kit....

Hey guys,

Since it was me that first introduced the relocated sensor to XrayMD I felt that I should talk a bit about my own experiences with this upgrade.

Don himself helped install the temperature sensor in my M5. It was scary seeing my car without the bumper in place. I managed to take a few pictures although in a lapse of judgment I happened to forget about taking a picture of where the sensor actually goes. I can tell you that it goes inside the front bumper directly behind the lower center grille. Before you ask about whether the airflow affects the sensor reading, nope, it's behind the plastic deflector behind the grille so the readings that the new sensor gets is fairly accurate. Looking at the layout I can definitely verify this. And the results were definitely noticable as XrayMD confirmed.

As for the website, it's ufmotorsport.com and Don can be reached via email at sales@ufmotorsport.com. I don't think he'd appreciate me posting his phone number on here.

Don is a friend of mine who happily agreed to perform the mod for free and I couldn't be happier about the end results!
