Mine is just tapped into my IC on the drivers side. I haven\'t had any issues with it so far. That has included trackdays and in town driving and town to town trips.

I just drilled an 8.0mm hole, into the Left End/Tank of a spare TMIC. Then Tapped a 3/8" NPT Thread. Opposite side from Turbo and Close to Engine Loom Points. Also right in Engine Bay Draft:

This is now my Link IAT Sensor Location:

That positition won\'t work out for you, Jas had issues reading air temps in a similar position but tapped in to the y pipe, Where you have it mounted is (pre) cooled air, you want to mount it on the other side of the tmic.

This is where i placed mine,bit rough atm as im still tweaking it but it works , its v7sti intercooler in a v4 now but i had it mounted in the same position with the factory v4 tmic after it failed in the y-pipe i\'m sure he\'ll confirm that story.

Yup, IAT sensor has to go on the cold side... or it\'ll run lean as buggery all the time because the air will actually be cooler/denser than the IAT is seeing. It\'ll also pull timing depending how your tune is set up.

As close to the throttle-body as possible folks!

On a side-note, the "Link" IAT sensors with the 1/8th BSP thread suck large balls, they are fragile as. I went and snarfed a couple of sensors from GM motors at Pickapart - some of the 4\'s and some of the V6\'s have them - the Link sensor uses the GM calibration curve anyway and the sensors are a. large and b. made of brass instead of plastic. Plus you just whip 8" of wire off with the plug and you get a ready made splice-in loom. Works well.

[hijacka]

That good to know Boon!

Yeah the whole link sensor is fragile and ya pay 100 bucks for it, Doesn\'t feel and look very well made or made to last haha

But it\'s fast reacting so good for tuning.

So is the GM one... it\'s a thermistor in a tube. That\'s about it.

Just thinking re this - wouldn\'t it make more sense to be on the cold side of the intercooler? There you\'ll be seeing some nice 100 degree plus intake temps, might throw things out a touch ;D

Done, thank you. I didn\'t consider the Hot Side/Cold Side thing ;D

Will your water crossover pipe fit with that sensor on the passengers side?

I haven\'t got a Water Pipe here to measure up, or check. But looking at my old pics...

No, good call. It won\'t. ;D

Right, third time lucky. This is my location for IAT Sensor. ;D

Either Side works. All Tanks are 3-4mm thick:

Inline with the throttle body is better IMO on the side that tips in towards the manifold because more air flows through that side at low throttle situations.

Here? ;D

[Burntrubber]

That\'s where I\'d put it. Is that the sensor your using haven\'t read whole thread sorry😆

Nah, that\'s a Pyrometer Probe - EGT\'s.

This is the Link G4 IAT Sensor, 3/8" BSP Thread:

You can see mine on the drivers side in this pic...

Similar location to yours and I haven\'t had any issues yet. I get the odd high temp in traffic but thats to be expected with a top mount.

Anyone got some recommendations on someone to wire up my bh for the link. and any idea of how much itl be would be awesome.

My original BH5B TT O2 Sensor, in Left Bank Header:

Version 8 STI Down Pipe for my conversion, with OEM Version 8 O2 Sensor:

BH5B (Version 5-6 STI), next to the Version 8 STI:

Version 5-6 STI O2 Sensor installed in my new DP. Ready for the J2 Version 5 STI ECU:

My new Headers have no O2 Port and I don\'t want to start drilling holes.

Temps will be higher on the Sensor, but I\'m guessing AFR readings would still be the same? Maybe shorter Sensor life? :-\

You can see the 10mm gallery branching off, just below the sensor port:
