I installed a 03/04 Cobra IAT sensor in my intake for custom tuning purposes when I put on the whipple about 3 years ago. I've been using the provided ford racing tune so the IAT sensor has never been wired in. I am finally looking to get a custom tune done. The sensor has never been used but I imagine it's probably got nice coat of oil residue on it by now.
My question is how often do these sensors need to be replaced?

I mounted the IAT sensor at the back of the manifold and will be dropping the k-member for a clutch swap, so this would be a good opportunity to get at the sensor if it should be replaced.

 

Probably never. Ask the manufacture. I would clean it off and use it.

You're also in the wrong forum. I think you are asking about an 03/04 Cobra?

 

I've got an 09 3V GT with an 03/04 Cobra sensor in it. But good call, should've checked with the cobra crowd first.

 

Never heard of that before.

 

Hey 6bangr.... If you have an '09 3V GT , you really don't need to drop the K-member to change your clutch/flywheel ... !!

 

My E-Force setup uses an 03-04 Cobra IAT sensor. I have cleaned it before using a couple squirts of MAF cleaner. Works fine.

 

A lot of tuners suggest putting in the IAT after the intercooler as opposed to having it on air intake tube with the MAF; which is how a few different PD blowers are setup. Mounting an IAT post-intercooler allows the computer to delay the timing if there's an issue with the intercooler and the air temp gets too hot.
I am regretting mounting that thing behind the compressor, it's a pain to get at. But I'll probably check to see how it looks anyways. If it looks a little gunked up I'll take jpplaw's advice and use a little MAF cleaner.
As for the clutch change, If I get access to a lift I'll just clock it out. If I'm stuck with jack stands I'll definitely try to clock it out but might have to resort to the k-member drop if clearance become an issue. Either way with the transmission out it' should be a little easier to get at the sensor.

 

Man that stinks. I think it would take me 20 minutes to pull my blower off. Just depends how sticky the RTV stuff sealing the manifold and blower is.

 

I'm just going to leave it if I have to pull the blower to get at it
